Base/1 Foundation Application

Presentation

What is BFC ?

RAD toolkitAllows building of secure database

applications with C# and ASP.NET“Database-centric” architectureSupports major databases: Microsoft,

Oracle, IBM, Sybase, MySQL

Features

Supports and extends leading databases– Data Dictionary: component used throughout BFC

which provides a description of records layout and indexes

Integration into Windows development (with Visual Studio)

Single, consistent API – Database access is wrapped with an easy-to-

learn API accessible with .NET, COM or MFC

Features

Rich client applications Distributed processing Enhanced security

– for checking/changing passwords, grouping users and granting/revoking database privileges

– setting per-application access privileges on the basis of user groups

– security groups– specifying prohibited actions– database session monitoring

Architecture

Grid computing: uses a “virtual supercomputer”, comprised of loosely coupled “batch job servers”

Three parts:– Rich client core components– Distributed batch processing services– Grid computing middleware

Rich client core components

Distributed batch processing services

Large jobs are broken down into smaller pieces that can be run individually– fault-tolerant – supports a high degree of database

concurrency– automatically balances workload across a

dynamic pool of available PCs

Grid computing middleware

the layer that ties together all the distributed components into a virtual supercomputer for large database applications

Advantages

BFC advantages – General Benefits

Lower cost of development and operations, in some cases cost has been reduced as much as 85%

Faster implementation and deployment, Customers can quickly prototype a distributed solution by using the BFC, which includes a large selection of programming tools and sample templates.

BFC advantages – Secure, industrial-strength applications

Over the course of 50,000+ hours of applications development, Base One created and refined its components for constructing screens, security and administration, graphics and reporting, batch processing, and numerous general purpose utilities, all with the same attention to rigorous error-handling and consistent reliability.

.

BFC advantages – Secure, industrial-strength applications

These facilities have been employed successfully in some of the world's largest companies, in applications dealing with billions of dollars, and millions of records, often containing highly sensitive information.

BFC advantages – Case Study

Deutsche Bank's Securities Custody System is one of the earliest successful examples of commercial grid computing. This large-scale financial application demonstrates the substantially lower costs and higher return on investment possible with Base One's distributed processing software, as compared to traditional architectures.

BFC advantages – Technical Benefits

Faster development through .NET and COM : C#, VB, VB.NET, ASP, ASP.NET (for web sites), VC++, and any other language that supports the popular COM or .NET  interfaces can use BFC components to do database access and security control

BFC advantages – Technical Benefits

Base One is integrated with commercial database environments, Base One operates through ODBC drivers and high-efficiency, direct connections to Microsoft SQL Server and Access, Oracle, IBM DB2, Sybase, and MySQL. (ADO.NET data providers are not required.) Databases can reside on Windows, Unix/Linux, and IBM midrange (AS400) and mainframe servers

BFC advantages – Technical Benefits

With Base One distributed computing technology, large-scale business and scientific applications are significantly less expensive to build, maintain, and administer and they are faster to implement.

BFC advantages – Technical Benefits

The benefits of Base One's approach derive not from specialization, but just the opposite: employing ordinary, under-utilized computer resources and using well established software technologies for database management and rapid application development.

BFC advantages – Technical Benefits

This dramatically reduces the total cost of ownership (TCO), with savings on the cost of new equipment and accompanying system software, as well as lower cost of programming. The net result is faster development and deployment of maintainable, production applications.

BFC disadvantagesand Limitations

One of the disadvantages involved by using this product is that it is not free

The main limitations for BFC are that it runs only on Windows OS and the only IDE accepted is Microsoft Visual Studio .NET 2008 SP1. So Microsoft dependence is the main limitation.

Tutorial

Log On

Autocorrect if the previous session failed

USER TYPES AND DATABASE LOGONS

Full User A "regular" user with a real database logon, e.g. "OWNER"

Lite User Lightweight user. NOT a real database logon, e.g. "LITE01”

Full Batch User For grid, cluster, distributed computing; real Db logon

Lite Batch User Same features as Full Batch User but NOT a real Db logon

Super User Does database access for Lite and Lite Batch Users

Database Setup User For connecting to an "empty" database

.INI file

All of the Base/1 Foundation Application's database connection settings come from its .INI file, B1_App.ini.

the default search order is to look for the .INI file first in the current directory and then in the windows directory

Database settings in the .ini file

DbNam (Database Name), always required DbTyp (Database Type), always required

Back end database system (DBMS) to be used, e.g. MSSQLSERVER DbQualifierStr (Database Qualifier String), required for most database types

e.g. schema, owner or database name DbServId (Database Server ID), required for most database types

e.g. server name or (local) DbConnTyp (Database Connection Type), optional

ODBC, except for Oracle (DirectAPI); can be left blank DbSetupUsrId (Database Setup User ID), required but only for certain activities

The Login ID used for initial creation of the BFC built-in record types InetServHostAddr (Internet Server Host Address), optional

Remote location (I.P. address, URL) of a database accessed via BIS InetServPortNum (Internet Server Port Number), only required if HostAddr used

Port number to use on an Internet Server (BIS) for doing database access SuperUsrId (Super User ID), optional

Real database login used by Lite Users for data access SuperUsrPassw (Super User Password), only required if SuperUsrId is supplied

Password for Super User. (This model assumes a secure room for computers)

Run batch jobs - summary

Build the necessary solutions Submit a batch job Start the batch job manager, which finds and

does the work

Run Distributed Batch Processing Services

Administrators and other interactive users can submit work to be picked up asynchronously by any batch machines that are available

MS Access is NOT suitable for multiple batch machines running together:

Run the Foundation App with a Remote Internet Server

Install BFC on a second PC to run the Internet Server Obtain the IP Address of the PC running the Internet Server. Set the Internet Server TCP/IP Information for the Foundation

Application Optionally, set the Internet Server Internet Report Path. Launch the Internet Server and the Foundation Application

For production systems, use BIS only on Win2000 or Win2003.

Client applications that are installed on XP connect to BIS on Win2000 or Win20003 without any problem

'XML Parsing Error '

If the source code is correct

Possible Solution: Reinstall the ASP.NET

Possible Problem: ASP.NET installed after IIS.

Other problems

The Directory where Access database is should be a virtual directory shared in network

The .ini file should be well configured
