Abrasives & Allied Products:

An abrasives is a hard, tough and wear resistant substance for grinding and polishing

operations. Manufactured through a complex and high technology process, these

abrasives are used in metal removal, cutting and finishing operations in almost all

industries.

Coated Abrasives :

These are manufactured by depositing grains over a backing material like cloth,

paper or fibre. Depending on the requirement of the customer, the backing material and

type of grains will vary. There are various types of grains likesintered aluminium

oxide, silicon carbide, zircon, emery and flint. The grains are of varied sizes referred as

'grits' and their sizes also vary from grit 12 to grit 2000.

The backing on which these grains are coated will vary depending on the industry and

application to which the coated abrasives are supplied.

Bonded Abrasives:

Bonded Abrasives are used in diverse applications like floor polishing,

fabrication, polishing, off-hand tool grinding and precision grinding of diverse products

like crank shaft, balls and razor blade across a wide spectrum of industries ranging from

automobile, construction, fabrication, steel, bearing etc

Super Abrasives:

Diamond and cubic boron nitride (CBN) are known as Super abrasives. Wheels

and tools made with these abrasives are used in high end applications . CUMI is present

in this segment, through its joint venture Wendt India Ltd., Bangalore, India.

The major user industries forsuper abrasives are automobile, engineering,

cutting tools, refractories, ceramics tile, glass and steel.

Allied Products:

Metal Working Fluids:

Apart from abrasives, CUMI also manufactures metal working fluids for grinding

applications.

In the metal working process, the right combination of machine, cutting tool and

metalworking fluid is required to produce an acceptable part. Therefore this product line

is a logical extension of CUMI's abrasives.

Power Tools:

CUMI recently launched a range of power tools used in metal working, construction,

wood working and interior decoration. Abrasives are used as accessories in power tools.

The Company's strong brand image and well established marketing network provide good

synergies for this product line with abrasives.

Ceramics:

The Ceramicsproduct group offers products which harness the heat resistance /

containment, wear resistance and insulation properties of ceramics and also corrosion

resistance properties of various materials.

Industrial ceramics:

Industrial ceramic materials are non-metallic, inorganic compounds Industrial ceramics

products made mostly of high alumina. They have high melting points, low wear

resistance, and a wide range of electrical properties.

The minerals used to make industrial ceramics materials are crushed or ground

into a fine powder that is purified by adding it to a solution and allowing a chemical

precipitate to form. The precipitate is then separated from the solution and heated to form

a highly pure powder. After purification, small amounts of wax are added to bind the

ceramic powder.

Plastics may also be added to provide pliability. The powder can then be shaped into

different objects by various moldin processes such as slip casting, pressure casting,

injection molding, and extrusion. After industrial ceramic materials are molded, they are

heated in a process known as densification to strengthen the material.

INTRODUCTION TO DATABASE

All of us are familiar with the term data. In fact, unknowingly we come across data in our

day to day life everyday. The age of a person, price of potato, number of students in a

school, pin code of a city, etc. are some examples of data. In our life we have to

remember so much of data. But it is easier for us to remember all information for a few

individuals. For example, you may be in a position to tell accurately the age, height,

complexion, income, educational qualification, residential address, etc. of your close

friends. But it is too difficult for you to memorise all these information for a large

number of individuals. Let us consider the example of National Open School (NOS).

Every year about one lakh students take admission in NOS. If you are asked to memorise

records of date of birth, subjects offered and postal address of all these students, it will

not be possible for you.

To deal with such problems we construct a database. We arrange all information about

students in a tabular form. We keep all the records so that if I am asked, How many

students are there in Economics? I am in a position to answer.

OBJECTIVES

After going through this lesson you will be in a position to

explain the concept of database

appreciate the features of database management system (DBMS)

learn about the software packages available in the market to deal with database

Invoke the dBASE III + programmes

explain the advantages of dBASE III +

work in dBASE III +.

What is A Database?

Let us begin with the concept database and its management. Database is a collection of

information in a structured way. We can say that it is a collection of a group of facts.


13/37

Your personal address book is a database of names you like to keep track of, such as

personal friends and members of your family.

Each piece of information in database is called a Field. We can definefieldas the

smallest unit in a database. Each field represents one and only one characteristic of an

event or item.

Functions of DBMS

DBMS free the programmers from the need to worry about the organization and

location of the data i.e. it shields the users from complex hardware level details.

DBMS can organize process and present data elements from the database. This

capability enables decision makers to search and query database contents in order to

extract answers that are not available in regular Reports.

Programming is speeded up because programmer can concentrate on logic of the

application.

It includes special user friendly query languages which are easy to understand by non

programming users of the system.

The various common examples of DBMS are Oracle, Access, SQL Server, Sybase,

FoxPro, Dbase etc.

Functions of a Database Management System:

There are several functions that a DBMS performs to ensure data integrity and

consistency of data in the database. The ten functions in the DBMS are: data dictionary

management, data storage management, data transformation and presentation, security

management, multiuser access control, backup and recovery management, data integrity

management, database access languages and application programming interfaces,

database communication interfaces, and transaction management.

1. Data Dictionary Management


14/37

Data Dictionary is where the DBMS stores definitions of the data elements and their

relationships (metadata). The DBMS uses this function to look up the required data

component structures and relationships. When programs access data in a database they

are basically going through the DBMS. This function removes structural and data

dependency and provides the user with data abstraction. In turn, this makes things a lot

easier on the end user. The Data Dictionary is often hidden from the user and is used by

Database Administrators and Programmers.

2. Data Storage Management

This particular function is used for the storage of data and any related data entry

forms or screen definitions, report definitions, data validation rules, procedural code, and

structures that can handle video and picture formats. Users do not need to know how data

is stored or manipulated. Also involved with this structure is a term called performance

tuning that relates to a databases efficiency in relation to storage and access speed.

3. Data Transformation and Presentation

This function exists to transform any data entered into required data structures. By using

the data transformation and presentation function the DBMS can determine the difference

between logical and physical data formats.

4. Security Management

This is one of the most important functions in the DBMS. Security

management sets rules that determine specific users that are allowed to access the

database. Users are given a username and password or sometimes through biometric

authentication (such as a fingerprint or retina scan) but these types of authentication tend

to be more costly. This function also sets restraints on what specific data any user can see

or manage.


15/37

5. Multiuser Access Control

Data integrity and data consistency are the basis of this function. Multiuser access

control is a very useful tool in a DBMS, it enables multiple users to access the database

simultaneously without affecting the integrity of the database.

6. Backup and Recovery Management

Backup and recovery is brought to mind whenever there is potential outside

threats to a database. For example if there is a power outage, recovery management is

how long it takes to recover the database after the outage. Backup management refers to

the data safety and integrity; for example backing up all your mp3 files on a disk.

7. Data Integrity Management

The DBMS enforces these rules to reduce things such as data redundancy, which

is when data is stored in more than one place unnecessarily, and maximizing data

consistency, making sure database is returning correct/same answer each time for same

question asked.

8. Database Access Languages and Application Programming Interfaces

A query language is a nonprocedural language. An example of this is SQL

(structured query language). SQL is the most common query language supported by the

majority of DBMS vendors. The use of this language makes it easy for user to specify

what they want done without the headache of explaining how to specifically do it.

9. Database Communication Interfaces

This refers to how a DBMS can accept different end user requests through different

network environments. An example of this can be easily related to the internet. A DBMS

can provide access to the database using the Internet through Web Browsers (Mozilla

Firefox, Internet Explorer, Netscape).

10. Transaction Management


16/37

This refers to how a DBMS must supply a method that will guarantee that all the

updates in a given transaction are made or not made.All transactions must follow what is

called the ACID properties.

The service provided by the DBMS includes:

Authorization services like log on to the DBMS, start the database, stop the Database

etc.

Transaction supports like Recovery, Rollback etc,

Import and Export of Data.

Maintaining data dictionary

User's Monitoring


17/37

ADVANTAGES OF DBMS

The DBMS (Database Management System) is preferred ever the conventional file

processing system due to the following advantages:

1. Controlling Data Redundancy - In the conventional file processing system, every

user group maintains its own files for handling its data files. This may lead to

Duplication of same data in different files.

Wastage of storage space, since duplicated data is stored.

Errors may be generated due to updation of the same data in different files.

Time in entering data again and again is wasted.

Computer Resources are needlessly used.

It is very difficult to combine information.

2. Elimination of Inconsistency - In the file processing system information is duplicated

throughout the system. So changes made in one file may be necessary be carried over to

another file. This may lead to inconsistent data. So we need to remove this duplication of

data in multiple file to eliminate inconsistency.

For example: - Let us consider an example of student's result system. Suppose that in

STUDENT file it is indicated that Roll no= 10 has opted for 'Computer'course but in

RESULT file it is indicated that 'Roll No. =l 0' has opted for 'Accounts' course. Thus, in

this case the two entries for z particular student don't agree with each other. Thus,

database is said to be in an inconsistent state. Sc to eliminate this conflicting information

we need to centralize the database. On centralizing the data base the duplication will be

controlled and hence inconsistency will be removed.

Data inconsistency are often encountered in every day life Consider an another example,

w have all come across situations when a new address is communicated to an

organization that we deal it (Eg - Telecom, Gas Company, Bank). We find that some of


18/37

the communications from that organization are received at a new address while other

continued to be mailed to the old address. So combining all the data in database would

involve reduction in redundancy as well as inconsistency so it is likely to reduce the costs

for collection storage and updating of Data.

Let us again consider the example of Result system. Suppose that a student having Roll

no -201 changes his course from 'Computer' to 'Arts'. The change is made in the

SUBJECT file but not in RESULT'S file. This may lead to inconsistency of the data. So

we need to centralize the database so that changes once made are reflected to all the

tables where a particulars field is stored. Thus the update is brought automatically and is

known as propagating updates.

3. Better service to the users - A DBMS is often used to provide better services to the

users. In conventional system, availability of information is often poor, since it normally

difficult to obtain information that the existing systems were not designed for. Once

several conventional systems are combined to form one centralized database, the

availability of information and its updateness is likely to improve since the data can now

be shared and DBMS makes it easy to respond to anticipated information requests.

Centralizing the data in the database also means that user can obtain new and combined

information easily that would have been impossible to obtain otherwise. Also use of

DBMS should allow users that don't know programming to interact with the data more

easily, unlike file processing system where the programmer may need to write new

programs to meet every new demand.

4. Flexibility of the System is Improved - Since changes are often necessary to the

contents of the data stored in any system, these changes are made more easily in a

centralized database than in a conventional system. Applications programs need not to be

changed on changing the data in the database.


19/37

5. Integrity can be improved - Since data of the organization using database approach is

centralized and would be used by a number of users at a time. It is essential to enforce

integrity-constraints.

In the conventional systems because the data is duplicated in multiple files so updating or

changes may sometimes lead to entry of incorrect data in some files where it exists.

For example: - The example of result system that we have already discussed. Since

multiple files are to maintained, as sometimes you may enter a value for course which

may not exist. Suppose course can have values (Computer, Accounts, Economics, and

Arts) but we enter a value 'Hindi' for it, so this may lead to an inconsistent data, so lack of

Integrity.

Even if we centralized the database it may still contain incorrect data. For example: -

Salary of full time employ may be entered as Rs. 500 rather than Rs. 5000.

A student may be shown to have borrowed books but has no enrollment.

A list of employee numbers for a given department may include a number of non

existent employees.

These problems can be avoided by defining the validation procedures whenever any

update operation is attempted.

6. Standards can be enforced - Since all access to the database must be through DBMS,

so standards are easier to enforce. Standards may relate to the naming of data, format of

data, structure of the data etc. Standardizing stored data formats is usually desirable for

the purpose of data interchange or migration between systems.

7. Security can be improved - In conventional systems, applications are developed in an

adhoc/temporary manner. Often different system of an organization would access

different components of the operational data, in such an environment enforcing security


20/37

can be quiet difficult. Setting up of a database makes it easier to enforce security

restrictions since data is now centralized. It is easier to control who has access to what

parts of the database. Different checks can be established for each type of access

(retrieve, modify, delete etc.) to each piece of information in the database.

Consider an Example of banking in which the employee at different levels may be given

access to different types of data in the database. A clerk may be given the authority to

know only the names of all the customers who have a loan in bank but not the details of

each loan the customer may have. It can be accomplished by giving the privileges to each

employee.

8. Organization's requirement can be identified - All organizations have sections and

departments and each of these units often consider the work of their unit as the most

important and therefore consider their need as the most important. Once a database has

been setup with centralized control, it will be necessary to identify organization's

requirement and to balance the needs of the competating units. So it may become

necessary to ignore some requests for information if they conflict with higher priority

need of the organization.

It is the responsibility of the DBA (Database Administrator) to structure the database

system to provide the overall service that is best for an organization.

For example: - A DBA must choose best file Structure and access method to give fast

response for the high critical applications as compared to less critical applications.

9. Overall cost of developing and maintaining systems is lower - It is much easier to

respond to unanticipated requests when data is centralized in a database than when it is

stored in a conventional file system. Although the initial cost of setting up of a database

can be large, one normal expects the overall cost of setting up of a database, developing

and maintaining application programs to be far lower than for similar service using

conventional systems, Since the productivity of programmers can be higher in using


21/37

non-procedural languages that have been developed with DBMS than using procedural

languages.

10. Data Model must be developed - Perhaps the most important advantage of setting

up of database system is the requirement that an overall data model for an organization be

build. In conventional systems, it is more likely that files will be designed as per need of

particular applications demand. The overall view is often not considered. Building an

overall view of an organization's data is usual cost effective in the long terms.

11. Provides backup and Recovery - Centralizing a database provides the schemes such

as recovery and backups from the failures including disk crash, power failures, software

errors which may help the database to recover from the inconsistent state to the state that

existed prior to the occurrence of the failure, though methods are very complex.


22/37

USES OF DATABASE IN DIFFERENT SECTORS:

Database is widely used all around the world in differnt sectors:

1.Banking: For customer information, accounts loans and banking transactions.

2.Airlines: For reservations and schedule information. Airlines were among the first to

use database in a geographically disturbed manner-terminals situated around the world

accessed the central database system through phone lines and other data networks.

3.Universities: For student information, course registrations and grades.

4.Credit card transactions: For purchases on credit cards and generation of monthly

statements.

5.Telecommunications: For keeping records of calls made, generating monthly bills,

maintaining balances on prepaid calling cards and storing information about the

communication networks.

6.Finance: For storing information about holdings, sales and purchase of financial

instruments such as stocks and bonds.

7.Sales: For customer, product and purchase information.

8.Manufacturing: For management of supply chain and for tracking production of itemsin factories, inventories of items in warehouses/stores and orders for items.

9.Human Resources: For information about employees, salaries, payroll taxes andbenefits and for generation of paychecks.

10.Web based services:For taking web users feedback,responses,resource sharing etc.


23/37

Purpose of using database systems:

To see why database management systems are necessary, let's look at a typical processing

system"supported by a conventional operating system.

1.The application is a savings bank: Savings account and customer records are kept in permanent system les.

Application programs are written to manipulate les to perform the following

tasks:

-Debit or credit an account.

- Add a new account.

- Find an account balance.

-Generate monthly statements.

2 .Development of the system proceeds as follows:

New application programs must be written as the need arises.

New permanent les are created as required.

but over a long period of time les may be in dierent formats, and

Application programs may be in dierent languages.

3. So we can see there are problems with the straight le-processing approach:

Data redundancy and inconsistency

- same information may be duplicated in several places

-All copies may not be updated properly.

Difficullty in accessing data:

-May have to write a new application program to satisfy an unusual request.

-Eg. nd all customers with the same postal code.

-Could generate this data manually, but a long job...

Data isolation

-Data in dierent les.

-Data in dierent formats.

-Dicult to write new application programs.

Multiple users

-Want concurrency for faster response time.


24/37

-Need protection for concurrent updates.

Security problems

-Every user of the system should be able to access only the data they are

permitted to see.

-Dicult to enforce this with application programs.

Integrity problems

- Data may be required to satisfy constraints.

These problems and others led to the development of database management systems.


25/37

What is dbfetch?

Dbfetch is an acronym for "database fetch". Dbfetch provides an easy way to retrieve

entries from various databases at the EBI in a consistent manner. It can be used from any

browser as well as well as within a web-aware scripting tool that uses wget, lynx or

similar.


26/37

ABOUT VISUAL BASIC:

Visual Basic (VB) is the third-generationevent-driven programming language

andintegrated development environment (IDE) from Microsoft for its COM

programming model. Visual Basic is relatively easy to learn and use.[1][2]

Visual Basic was derived from BASICand enables the rapid application development

(RAD) ofgraphical user interface (GUI)applications, access to databasesusing Data

Access Objects, Remote Data Objects, orActiveX Data Objects, and creation ofActiveX

controls and objects. Scripting languages such as VBAand VBScript are syntactically

similar to Visual Basic, but perform differently.[3]

A programmer can put together an application using thecomponents provided with

Visual Basic itself. Programs written in Visual Basic can also use the Windows API, but

doing so requires external function declarations.

The final release was version 6 in 1998. Microsoft's extended support ended in March

2008 and the designated successor was Visual Basic .NET(now known simply as Visual

Basic).

FEATURES:

Like the BASIC programming language, Visual Basic was designed to be easily learned

and used by beginner programmers. The language not only allows programmers to create

simple GUI applications, but can also develop complex applications. Programming in VB

is a combination of visually arranging componentsorcontrols on a form, specifying

attributes and actions of those components, and writing additional lines ofcode for more

functionality. Since default attributes and actions are defined for the components, a

simple program can be created without the programmer having to write many lines of

code. Performance problems were experienced by earlier versions, but with faster

computers and native code compilation this has become less of an issue.

Although programs can be compiled into native code executables from version 5

onwards, they still require the presence of runtime libraries of approximately 1 MB in

size. This runtime is included by default in Windows 2000and later, but for earlier

versions ofWindows like 95/98/NT it must be distributed together with the executable.

handlers associated with them. Default values are provided when the control is created,

but may be changed by the programmer. Many attribute values can be modified during

run time based on user actions or changes in the environment, providing a dynamic

application. For example, code can be inserted into the form resize event handler to

reposition a control so that it remains centered on the form, expands to fill up the form,

etc. By inserting code into the event handler for a keypress in a text box, the program can

automatically translate the case of the text being entered, or even prevent certain

characters from being inserted.

Visual Basic can create executables (EXE files), ActiveX controls, or DLL files, but is

primarily used to develop Windows applications and to interface database systems.

Dialog boxes with less functionality can be used to provide pop-up capabilities. Controls

provide the basic functionality of the application, while programmers can insert

additional logic within the appropriate event handlers. For example, a drop-down

combination box will automatically display its list and allow the user to select any

element. An event handler is called when an item is selected, which can then execute

additional code created by the programmer to perform some action based on which

element was selected, such as populating a related list.

Alternatively, a Visual Basic component can have no user interface, and instead provide

ActiveX objects to other programs viaComponent Object Model (COM). This allows for

server-side processing or an add-in module.

The language is garbage collectedusing reference counting, has a large library of utility

objects, and has basic object oriented support. Since the more common components are

included in the default project template, the programmer seldom needs to specify

additional libraries. Unlike many other programming languages, Visual Basic is generally

not case sensitive, although it will transform keywords into a standard case configuration

and force the case of variable names to conform to the case of the entry within the

symbol table. String comparisons are case sensitive by default, but can be made case

insensitive if so desired.

The Visual Basic compiler is shared with other Visual Studio languages (C, C++), but

restrictions in the IDE do not allow the creation of some targets (Windows model DLLs)

and threading models.

Microsoft Office Access, previously known as Microsoft Access, is a relational database

management system from Microsoft that combines the relational Microsoft Jet Database

Engine with a graphical user interfaceand software-development tools. It is a member of

the Microsoft Office suite of applications, included in the Professional and higher

editions or sold separately. In mid-May 2010, the current version of Microsoft Access

2010 was released by Microsoft in Office 2010; Microsoft Office Access 2007 was the

prior version.

Access stores data in its own format based on the Access Jet Database Engine. It can also

import or link directly to data stored in other applications and databases.[1]

Software developersand data architects can use Microsoft Access to develop application

software, and "power users" can use it to build simple applications. Like otherOffice

applications, Access is supported by Visual Basic for Applications, an object-oriented

programming language that can reference a variety of objects including DAO (Data

Access Objects), ActiveXData Objects, and many other ActiveX components. Visual

objects used in forms and reports expose their methods and properties in the VBA

programming environment, and VBA code modules may declare and call Windows

operating-system functions.

USES:

Microsoft Access is used to make databases.

When reviewing Microsoft Access in the real world, it should be understood how it is

used with other products. An all-Access solution may have Microsoft Access Forms and

Reports managing Microsoft Access tables. However, Microsoft Access may be used

only as the 'front-end', using another product for the 'back-end' tables, such as Microsoft

SQL Serverand non-Microsoft products such as Oracle and Sybase. Similarly, some

applications will only use the Microsoft Access tables and use another product as a front-

end, such as Visual BasicorASP.NET. Microsoft Access may be only part of the

solution in more complex applications, where it may be integrated with other

technologies such as Microsoft Excel,Microsoft OutlookorActiveX Data Objects.

Access tables support a variety ofstandard field types,indices, and referential integrity.

Access also includes aqueryinterface, forms to display and enter data, and reports for

printing. The underlying Jet database, which contains these objects, is multiuser-aware

and handles record-locking and referential integrity including cascadingupdatesand

deletes.

Repetitive tasks can be automated through macros withpoint-and-clickoptions.

Microsoft Access is popular among non-programmers and professional developers alike.

Non-programmers can create visually pleasing and relatively advanced solutions with

very little or no code. It is also easy to place a database on a network and have multiple

users share and update data without overwriting each other's work. Data is locked at the

record level which is significantly different from Excelwhichlocks the entire

spreadsheet.

Microsoft offers a wide range oftemplate databases within the program and for download

from theirwebsite. These options are available upon starting Access and allow users to

enhance a database with pre-defined tables,queries, forms, reports, and macros. Popular

templates include tracking contacts, assets, issues, events, projects, and tasks. Templates

do not include VBA code.

Microsoft Access offers also the ability for programmers to create solutions using the

programming languageVisual Basic for Applications (VBA), which is similar to Visual

Basic 6.0 (VB6)and used throughout the Microsoft Office programs such as Excel,

Word,Outlookand PowerPoint. Most VB6 code, including the use of Windows API

calls, can be used in VBA.Power users and developers can extend basicend-user

solutions to a professional solution with advanced automation, data validation, error

trapping, andmulti-usersupport.

Database solutions created entirely in Microsoft Access are well suited for individual and

workgroup use across a network. The number of simultaneous users that can be supported

depends on the amount of data, thetasks being performed, level of use, and application

design. Generally accepted limits are solutions with 1 GB or less of data (Access supports

up to 2 GB) and performs quite well with 20 or fewer simultaneous connections (255

concurrent users are supported). This capability is often a good fit fordepartment

solutions. If using an Access database solution in a multi-user scenario, the application

should be "split". This means that the tables are in one file called theback end (typically

stored on a shared network folder) and the application components (forms, reports,

queries, code, macros, linked tables) are in another file called the front end. The linked

tables in the front end point to the back end file. Each user of the Access application

would then receive his or her own copy of the front end file.

Applications that run complex queries or analysis across large datasets would naturally

require greaterbandwidth and memory. Microsoft Access is designed toscale to support

more data and users by linking to multiple Access databases or using aback-enddatabase

like Microsoft SQL Server. With the latter design, the amount of data and users can scale

to enterprise-level solutions.

Microsoft Access's role in web development prior to version 2010 is limited. User

interface features of Access, such as forms and reports, only work in Windows. In

versions 2000 through 2003 an Access object type called Data Access Pages created

publishable web pages. Data Access Pages are no longer supported. TheMicrosoft Jet

Database Engine, core to Access, can be accessed through technologies such as ODBC or

OLE DB. The data (i.e., tables and queries) can be accessed by web-based applications

developed in ASP.NET, PHP, orJava.

Access 2010 allows databases to be published to SharePoint 2010 web sites running

Access Services. These web-based forms and reports run in any modern web browser.

The resulting web forms and reports, when accessed via a web browser, don't require any

add-ins or extensions (e.g. ActiveX, Silverlight).

In enterprise environments, Microsoft Access is particularly appropriate for meetingend-

userdatabase needs and forrapid application development. Microsoft Access is easy

enough for end users to create their own queries, forms and reports, laying out fieldsand

groupings, setting formats, etc. This capability allows professional developers, as well as

end users, to develop a wide range of applications to fulfill the needs of an organization

or commercial purpose. Many technology departments enjoy Access's ease of use, thus

allowing departmental users the ability to create highly focused applications, while

allowing the technology departments to focus on the enterprise level systems that provide

the information (enterprise data) to supported departments.

A compiledMDE orACCDE version of an Access database can be created to prevent

users from getting to the design surfaces to modify module code, forms, and reports. This

is often used in environments where end-user modifications are discouraged or the

application's code should be kept private.

Microsoft offers a runtime version of Microsoft Access 2007 fordownload. This allows

people to create Access solutions and distribute it for use by non-Microsoft Access

owners (similar to the way DLLs orEXEs are distributed). Unlike the regular version of

use its design surfaces.

ABOUT B2B WEBSITES:

Six Reasons to Use a B2B Marketplace:

Considering their features and capabilities B2B marketplaces are still quite underused.

However, the trend is changing and many companies started to realize the immense

potential these promising online channels store. Now the common view is adoption of a

marketplace as a sales or purchase channel will change the way a company handles its

sales and procurement bringing improved productivity and sustained profitability to its

bottom line.

What is a B2B marketplace?

Business to business marketplace is an online venue where buyers and sellers come to

communicate, collaborate and do business transactions. A B2B marketplace handles a

large number of participant companies as a community. The main objective of a

marketplace is to organize a business platform filled with features that allows members to

conduct various business processes over the Internet and increase company productivity.

Two primary indicators of company productivity are Increased Revenue and Cost Saving.

Both of these two indicators will show improved result if a company incorporates

marketplace features in possible fields of its business operations.

Lets check out some compelling reasons why companies should start using B2B

marketplace without hesitation:

1. B2B marketplace is a large community of buyers and sellers

By becoming a member of a B2B marketplace companies get instant access to thousands

of prospective buyers and supplier. An average B2B marketplace has over 100 thousand

members. This gives an opportunity to expand business by finding new customers and

2. Real time marketplace allows buyers to take quick decision

Buyers can study, compare and research a product offered on a marketplace without

leaving the marketplace. This ability of a B2B marketplace to give key information

necessary to make a purchasing decision helps buyers to take a faster buying decision.

Study shows that a full 47 percent of the buyers visit a site without having all the

necessary information needed to purchase a product. Products offered on a marketplace

are integrated with the eCatalog and sellers Web Store. This helps to increase buyer

conversion rate significantly.

3. Sophisticated eCatalog helps display comprehensive product features

An eCatalog is an Online product content management solution with powerful user

interface which provides efficient navigation, searching and integration capabilities to

organize and publish product information and enable real-time handling of business

processes related to buying and selling.

It stores product content in a single database and organizes product information under a

predefined categorized hierarchy. It also has sophisticated search capabilities so that

buyers can locate products easily.

Studies show, in many cases, buyers are unable to take conclusive procurement decisions

due to poor content of the product resulting lost business opportunity for companies. To

avoid this all B2B marketplaces adopt one kind or another advanced eCatalog system

which delivers a compelling value proposition. As a result, companies can expect

increased revenue, better customer satisfaction, and shorter sales cycle.

4. Sales solution expedites selling process and reduces overhead costs

The sales chain integrated to a B2B marketplace covers every stage of selling process

including quotation, negotiation, billing and shipment tracking. Electronic sales process

considerably reduces sales cycle enabling lower processing costs. Electronic sales

solution also helps minimizing document errors often associated with paper based

systems.

5. eProcurement solution makes buying easier

Electronic procurement is the method of conducting transactions between buyers and

suppliers over the Internet. An eProcurement system is an integral part of a B2B

marketplace. Procurement through a B2B marketplace has many undisputed advantages.

Transaction costs get reduced thanks to streamlined transaction process. It saves time and

stops rogue spending by employees.

Aberdeen Group estimates that automating procurement activities will save midsize

companies $2 million per year. And that's not to say anything of the cost savings

resulting from better supply chain collaboration.

6. Web Store brings new opportunities to companys retail business

While through the marketplace you can tap into the wide range of B2B buyers, B2B

marketplace feature that allows participant companies to build their web store using the

same eCatalog gives a magnificent opportunity to target a totally different market

segment. This by itself is a unique opportunity as recent studies showed that an increased

number of small companies with less than 20 employees are making more than 25

percent of their sales online.

The impact of the Internet

The Internet has become an integral component of the customer relationship management

strategy for business marketers. Dwyer and Tanner (2006) note that business marketers

not only use the Internet to improve customer service but also to improve opportunities

with distributors.

According to Anderson and Narus (2004), two new types of resellers have emerged as

by-products of the Internet: infomediaries and metamediaries. Infomediaries, such as

Google and Yahoo, aresearch engine companies that also function as brokers, or

middlemen, in the business marketing world. They charge companies fees to find

information on the Web as well as for banner andpop-up ads and search engine

optimization services. Metamediaries are companies with robust Internet sites that furnish

customers with multiproduct, multivendor and multiservice marketspace in return for

commissions on sales.

With the advent of b-to-b exchanges, the Internet ushered in an enthusiasm for

collaboration that never existed beforeand in fact might have even seemed ludicrous 10

years ago. For example, a decade ago who would have imagined Ford,General Motors

andDaimlerChryslerentering into a joint venture? That's exactly what happened after all

three ofthe Big Three began moving their purchases online in the late 1990s. All three

companies were pursuing their own initiatives when they realized the economies of scale

they could achieve by pooling their efforts. Thus was born what then was the world's

largest Internet business when Ford's Auto-Xchange and GM's TradeXchange merged,

with DaimlerChrysler representing the third partner.

While this exchange did not stand the test of time, others have, including Agentrics,

which was formed in 2005 with the merger of WorldWide Retail Exchange and

GlobalNetXchange, or GNX. Agentrics serves more 50 retailers around the world and

more than 300 customers, and its members have combined sales of about $1 trillion. Hutt

and Speh (2001) note that such virtual marketplaces enable companies and their suppliers

to conduct business in real time as well as simplify purchase processes and cut costs.

Conclusion:

The aim of the research presented in this thesis is to contribute to build the

database using the internet. This process always helps to implement the database for the

businesss people and for the telemarketers. By using b2b websites they can easily get the

datas from the web.

Internet facilitates for providing a flexible computer system. Experiences from

this research project show that Internet is suitable for developing a computer system that

can be rapidly adapted to various learning situations, particularly to the Business

throughout the world and for the various transactions.

The process of this project is to fetch the urls from the b2b websites and connect

it to the visualbasic as a backend and Microsoft as a front end.

Finally, it creates an efficient database for the users who can access the

information.
