1. INTRODUCTION

Performance management includes activities to ensure that goals are consistently being

met in an effective and efficient manner. Performance management can focus on the

performance of an organization, a department, employee, or even the processes to build a

product or service, as well as many other areas.

Performance Management as referenced on this page is a broad term. See Aubrey

Daniels for a detailed explanation of the origin of the term Performance Management (PM)

which was coined by Dr. Aubrey C. Daniels in the late 1970s to describe a technology (i.e.,

science imbedded in applications methods) for managing both behavior and results, the two

critical elements of what is known as performance.

The Application proposed is used to track the potential level of the lecturer by considering

the grade levels given by the students by answering to the given set of questions. Each students is

assigned with a username and password by which they can login and participate in the

questionnaire setting the responses from multiple choice answers based on which the grade of the

lecturer is calculated. The individual performance on the given criteria and the overall grade is

decided finally by the administrator.

This helps the management of find the efficiency of the lecturers in the college and decides

their performance level which leads to their growth in the college.

1.1 Present System

In the current scenario, the information of the performance provided by the colleges, are

maintained offline. It becomes complex for the managing authority, to maintain the performance

of the faculty with grade specifications. It also is difficult to track the information of the

renewals to trace the completed & pending renewals data. The information of the performance

staff is maintained in person and the performance information is offline making it difficult to

trace their efficiencies.

2

1.2 Proposed System

The application that is proposed online works under the control of the central server were the

students and college administrators can access them from remote sources. Managing employee

or system performance facilitates the effective delivery of strategic and operational goals. There

is a clear and immediate correlation between using performance management programs or

software and improved business and organizational results.

For employee performance management, using integrated software, rather than a spreadsheet

based recording system, may deliver a significant return on investment through a range of direct

and indirect sales benefits, operational efficiency benefits and by unlocking the latent potential in

every employees work day i.e. the time they spend not actually doing their job.

3. ANALYSIS

3.1 SYSTEM ANALYSIS

The analysis of the existing system has to be carried to learn the details of the existing system.

System analysis is the process of gathering and interpreting facts, diagnosing problems and using

the information to recommend improvements to the system. Only after the system’s analysis we

can begin to determine how and where a computer information system can benefit all the users of

the system. This accumulation of the system called a system’s study.

For employee performance management, using integrated software, rather than a

spreadsheet based recording system, may deliver a significant return on investment through a

range of direct and indirect sales benefits, operational efficiency benefits and by unlocking the

latent potential in every employees work day i.e. the time they spend not actually doing their job.

3.2 FEASIBILITY ANALYSIS

3.2.1 TECHNICAL FEASIBILITY

Keeping in mind the existing system network, s/w & H/w, already available the PMS

application generated in Java provides an executable file that requires JVM that provides

compatibility from windows98 without having to load JAVA software.

No additional hardware or software is required which makes smart audit technically feasible

3.2.2 OPERATIONAL FEASIBILITY

The application PMS does not require additional manual involvement or labor towards

maintenance of the system. Cost for training is minimized due to the user friendliness of the

developed application.

Recurring expenditures on consumables and materials are minimized.

7

3.2.3 ECONOMIC FEASIBILITY

The system is economically feasible keeping in mind:

Lesser investment towards training.

One time investment towards development.

Minimizing recurring expenditure towards training, facilities offered and consumables.

The system as a whole is economically feasible over a period of time.

Many feasibility studies are disillusioning for both users and analysts. First, the study often

presupposes that when the feasibility document is being prepared, the analyst is in a position to evaluate

solutions. Second, most studies tend to overlook the confusion inherent in system development-the

constraints and the assumed attitudes. If the feasibility study is to serve as a decision document, it must

answer three key questions.

3.3 JAVA

3.3.1 OVERVIEW OF JAVA

An Object Oriented Programming Language(OOPL) developed at Sun Microsystems. A

Virtual Machine Run Time Environment that can be embedded in web browser (IE, NN). Java is

a powerful but lean object oriented programming language.It has generated a lot of excitement

because it makes it possible to program for Internet by creating applets, programs that can be

embedded in web page.

The context of an applet is limited only by one’s imagination. For example, an applet can

be an animation with sound, an interactive game or a ticker tape with constantly updated stock

prices. Applets can be serious application like word processor or spreadsheet.

But Java is more than a programming language for writing applets. It is being used more

and more for writing standalone applications as well. It is becoming so popular that many people

believe it will become standard language for both general purpose and Internet programming.

8

There are many buzzwords associated with Java, but because of its spectacular growth in

popularity, a new buzzword has appeared ubiquitous. Indeed, all indications are that it will soon

be everywhere.

Java is actually a platform consisting of three components:

Java Programming Language.

Java Library of Classes and Interfaces.

Java Virtual Machine.

It also has a Standardized set of Packages (Class, Interfaces):

Creating Graphical User Interfaces

Controlling Multimedia Data

Communicating over Network

The following sections will say more about these components:

3.3.2 FEATURES OF JAVA

i. JAVA IS PORTABLE:

One of the biggest advantages Java offers is that it is portable. An application written in Java

will run on all the major platforms. Any computer with a Java based browser can run the

applications or applets written in the Java Programming Language. A programmer no longer

has to write one program to run on a Macintosh, another program to run on a windows

machine, still another to run on a UNIX machine, and so on. In other words, with Java,

developers write their programs only once. The virtual machine is what gives Java is cross

platform capabilities.

9

ii. JAVA IS OBJECT ORIENTED

The Java programming language is object oriented, which makes program design focus onThe Java programming language is object oriented, which makes program design focus on

what you are dealing with rather than on how you are going to do something. This makes itwhat you are dealing with rather than on how you are going to do something. This makes it

more useful for programming in sophisticated projects because one can break the thingsmore useful for programming in sophisticated projects because one can break the things

down into understandable components. A big benefit is that these components can then bedown into understandable components. A big benefit is that these components can then be

reused.reused.

iii. JAVA MAKES IT EASY TO WRITE CORRECT CODE

In addition to being portable and object oriented, Java facilitates writing correct code.

Programmers spend less time writing Java code and a lot less time debugging it. In fact,

developers have reported slashing development time by as much as two thirds.

3.4 HTML3.4 HTML

3.4.1 INTRODUCTION

The Hyper Text Markup Language (HTML) is a simple markup language used to create

hypertext documents that are portable from one platform to another. HTML documents are

SGML documents with generic semantic that are appropriate for representing information from a

wide range of applications. This specification defines HTML version 3.2. HTML 3.2 aims to

capture recommended practice as of early ‘96 and as such to be used as a replacement for HTML

2.0(RF1866).

A set of instructions embedded in a document is called Markup Language. These

instructions describe what the document text means and how it should look like in a

display.Hyper Text Markup Language (HTML) is the language used to encode World Wide Web

documents. It is a document layout and hyperlink specification language that defines the syntax

and placement of special embedded directions that are not displayed by a web browser, but tells

it how to display the contents of the documents including text, images and other supported

media.

10

3.4.2 USE OF HTML

Web site is a collection of pages, publications, and documents that reside on web sever.

While these page publications, and a document as a formatted in any single format. You should

use HTML for home page and all primary pages and the site. This will enable the millions of

web users it easily access and to take advantage of your website.

3.5 JAVA SERVER PAGES (JSP)

3.5.1 INTRODUCTION

Java Server Pages (JSP's) permit server side Java logic to reside within the requested

document. Upon request of a JSP document the server activates the specified JSP. The JSP then

becomes responsible for providing an HTML response.

The server side logic within a JSP is written in Java. The Java code segments, referred to

as scriptlets, are generally responsible for providing dynamic HTML content to the JSP's

response HTML. The JSP itself is compiled by the server, and is executed as an object that

extends the Java Servlet API. As such, the HTTP Servlet request and response objects are

available by the scriptlets defined within the JSP.

If we consider a 3-tier architectural WEB application, the browser becomes the client side

application. The user communicates requests to the WEB/app server via the browser. The

presentation layer receives the client requests and prepares the response and server side business

functionality is executed. In the context of this example, the JSP engine represents the

presentation layer. It is responsible for processing requests and responses. Additional messages

may be passed between this layer and that which handles business processes represented below

as EJB’s.

11

3.5.2 THE TECHNOLOGY

JSP technology uses XML - like tags and scriptlets. They are used to encapsulate

presentation logic within the JSP. They can also initiate messages to distributed or server-side

applications. The logical separation of presentation and business logic lies in the implementation

of the JSP.

Enterprise Java Beans provide a distinct relationship between the implementation of

business logic and the remote interfaces provided to the EJB client. The use of an EJB typically

follows the pattern:

The client application identifies itself to the server.

The client application uses the Java Naming Directory service to locate the

desired EJB.

The client application retrieves a handle to the EJB Home and

subsequently Remote interfaces.

The remote interface contains methods that the client is permitted to use. They

represent a summary of the business logic that is implemented by the bean. The implementation

logic is defined within the primary bean class. All IPC, database and resource details are

restricted to the bean class.

12

In constructing a JSP document, the creation of the HTML base is a prudent step. It

becomes the visual template that JSP scriptlets are merged into. The post execution HTML

produced from the completed JSP should be that of the original HTML document. With the

exception of comment, dynamically generated HTML sections and JSP content substitutions.

The scripting logic, except for where desired, is completely non visual in regard to the response

HTML text.

The construction of the HTML layout conceivably begins with a Web developer. The

creation of the JSP pages would be similar if not identical to the methods used to construct

industry HTML pages.

3.5.3 CONCLUSION

As with other tools of the trade, innovations and nuances to existing tools do not

invalidate existing design methodologies. They do however provide new versatility and the

expansion of possibilities with regard to application design.

Custom tag extensions, in contrast to standard tags, provide the application builder the

ability to define custom tags to satisfy some functionality not provided by the standard API. To

benefit by using tag extensions to reduce the amount of Java functionality that the JSP API

provides, might seem oxymorinic, and it is.

3.6

MICROSOFT ACCESS

3.6.1 INTRODUCTION

Access is a database management system. Databases are an important part of everyday

use. We use them anywhere we use computers, at home, and in the fields of medicine,

education, law, business, engineering and government.

13

A database is a collection of data and facts that are related to a particular object or

purpose, such as tracking customer orders or maintaining a music collection. If your database

isnot stored on a computer, or only parts of it are on the computer, you may be tracking

information from a variety of sources that you have to coordinate and organize yourself.

In Access, the heart of the database is the Table. One or more tables comprise a database.

In addition to tables, a database can contain other objects such as queries, reports, forms and

other components.These objects allow you to view and manipulate the data contained in the

database in variety of ways.

3.6.2 DESIGNING A DATABASE

Good design is a key factor of successful database building. A well designed database

can lead to more efficient use of queries, forms, and reports, and can increase the reliability of

the extracted information. In addition, an effectively designed database will be easier to expand

as you organization’s information requirements grow and change.

Although there are guidelines to assist you in designing your database, there is no such

thing as a perfect database design. Designing information systems always involves a degree of

compromise. The purpose of this appendix is to provide a general overview of good database

design principles. These guidelines should not be viewed as hard and fast rules, but rather

suggestions for making your database design decision.

Database Objects Description

Table The primary units of a database that stores field names, field

description, field controls and field data. Tables display multiple

records in a row/column format similar to a spreadsheet layout.

14

Query A structured guideline used to search database tables and retrieve

records that meet specific conditions.

Form An aesthetically pleasing layout of table data designed to display one

record on-screen at a time.

Report An organized format of database data designed to generate printouts

that provide meaningful information.

Pages A data access page is a special type of Web page designed for

viewing and working with data from an Internet or Intranet data that

is stored in a Microsoft Access database or a Microsoft SQL Server

database. The data access page may also include data from other

sources, such as Microsoft Excel.

Macros A mini program that stores a set of instructions designed to perform a

particular task.

Module A collection of Visual Basic programming procedures stored together

to customize the Access environment.

15

3.6.3 TABLE DESIGN VIEW:

In table design View, you must specify the fields, specify the data type for each field,

assign the size for text and number fields, assign the primary key (see glossary for definition)

and save the table yourself.

3.6.4 DATASHEET VIEW:

In data sheet view data types are very important to creating a database. There are 10

different types to choose from. The data type determines what kind of information may be

entered in a field.You can always change the data type of a field after you have entered data into

it. However, it may be a difficult process if the data field conflicts with the current data type (for

example, changing a text field to a number field). The table below shows the specifics on each

data type.

Setting Type of Data

Text(default

setting for all field)

Text or combination of text and numbers, as well as numbers that

don’t require calculations, such as phone numbers. Up to 255

characters or the length set by the Field Size property, whichever is

less.

Memo

Lengthy text or combinations of text and numbers. Up to 65,536

characters.

Number Numeric data used in mathematical calculations.

Date / Time Date and time values for years 100 through 9999.

Currency

Currency values and numeric data used in mathematical

calculations involving data with one to four decimal places.

Accurate to 15 digits on the left side of the decimal separator and to

4 digits on the right side.

AutoNumber A unique sequential (incremented by 1) number or random number

16

assigned by Microsoft Access whenever a new record is added to a

table. AutoNumber fields cannot be updated.

Yes / No

Yes and No values and fields that contain only one of two values

(Yes/No, True/False, or On/Off).

OLE Object

An object (such as a Microsoft Excel spreadsheet, a Microsoft

Word document, graphics, sound, or other binary data) linked to

embedded in a Microsoft Access table.

Hyperlink Text or combination of text stored as text and used as hyperlink

4. DESIGN

4.1 DATA FLOW DIAGRAMS.

The development of DFD’S is done in several levels. Each process in lower level

diagrams can be broken down into a more detailed DFD in the next level. The lop-level diagram

is often called context diagram. It consists of A data flow diagram is graphical tool used to

describe and analyze movement of data through a system. These are the central tool and the

basis from which the other components are developed. The transformation of data from input to

output, through processed, may be described logically and independently of physical components

associated with the system. These are known as the logical data flow diagrams. The physical

data flow diagrams show the actual implements and movement of data between people,

departments and workstations. A full description of a system actually consists of a set of data

flow diagrams. Using two familiar notations Yourdon, Gane and Sarson notation develops the

data flow diagrams. Each component in a DFD is labeled with a descriptive name. Process is

further identified with a number that will be used for identification purpose single process bit,

which plays vital role in studying the current system. The process in the context level diagram is

exploded into other process at the first level DFD.

The idea behind the explosion of a process into more process is that understanding at one

level of detail is exploded into greater detail at the next level. This is done until further

explosion is necessary and an adequate amount of detail is described for analyst to understand

the process. Larry Constantine first developed the DFD as a way of expressing system

requirements in a graphical from, this lead to the modular design.

20

4.1.2 DFD SYMBOLS:

In the DFD, there are four symbols

1. A square defines a source(originator) or destination of system data

2. An arrow identifies data flow. It is the pipeline through which the information flows

3. A circle or a bubble represents a process that transforms incoming data flow into

outgoing data flows.

4. An open rectangle is a data store, data at rest or a temporary repository of data.

Process that transforms data flow.

Source or Destination of data

Data flow

Data Store

21

4.1.3 CONSTRUCTING A DFD

Several rules of thumb are used in drawing DFD’S:

1. Process should be named and numbered for an easy reference. Each name should

be representative of the process.

2. The direction of flow is from top to bottom and from left to right. Data

traditionally flow from source to the destination although they may flow back to the

source. One way to indicate this is to draw long flow line back to a source.

3. When a process is exploded into lower level details, they are numbered.

4. The names of data stores and destinations are written in capital letters.

Process and dataflow names have the first letter of each work capitalized

A DFD typically shows the minimum contents of data store. Each data store should

contain all the data elements that flow in and out. Questionnaires should contain all the data

elements that flow in and out. Missing interfaces redundancies and like is then accounted for

often through interviews.

4.1.4 SAILENT FEATURES OF DFD’S

1. The DFD shows flow of data, not of control loops and decision are

controlled considerations do not appear on a DFD.

2. The DFD does not indicate the time factor involved in any process

whether the dataflow take place daily, weekly, monthly or yearly.

3. The sequence of events is not brought out on the DFD

22

4.2 UNIFIED MODELING LANGUAGE

4.2.1 Unified Modeling Language

The unified modeling language allows the software engineer to express an analysis model

using the modeling notation that is governed by a set of syntactic semantic and pragmatic rules.

A UML system is represented using five different views that describe the system from

distinctly different perspective.

Each view is defined by a set of diagram, which is as follows.

User Model View

The analysis representation describes a usage scenario from the end-users

perspective.

Structural model view

In this model the data and functionality are arrived from inside the system.

This model view models the static structures.

Behavioral Model View

It represents the dynamic of behavioral as parts of the system,depicting the

interactions of collection between various structural elements described in the user model and

structural model view.

Implementation Model View

In this the structural and behavioral as parts of the system are represented as

they are to be built.

23

4.2.2 INTRODUCTION TO THE UNIFIED MODIFIED LANGUAGE

Building a model for a software system prior to its construction is as essential

as having a blueprint for building a large building. Good models are essential for

communication among project teams. As the complexity of the systems increases, so

does the importance of good modeling techniques.

A modeling language must include:

Model elements- fundamentally modeling concepts and semantics.

Notation-visual rendering of model elements

Guidelines-expression of usage within trade

The use of visual notation to represent or model a problem can provide us several

benefits relating to clarity, familiarity, maintenance, and simplification. The main reason for

modeling is the reduction of complexity. The Unified Modeling Language (UML) is a set of

notations and conventions used to describe and model an application. The UML is intended to

be a universal language for modeling systems, meaning that it can express models of

many different kinds and purposes, just as a programming language or a natural language

can be used in different ways.

A model” is an abstract representation of a system , constructed to understand the

system prior to building or modifying it. The term “system” is used here in a broad

sense to include any process or structure.

The UML is not intended to be a visual programming language in the sense

of having all the necessary visual and semantic support to replace programming

languages. However, the UML does have a tight mapping to a family of object-oriented

languages, so that you can get the best of both worlds.

24

The primary goals in the design of the UML were as follows:

1. Provide users ready-to-use, expensive visual modeling languages so they can develop and

exchange meaningful models.

2. Provide extendibility and specialization mechanisms to extend the core concepts.

3. Be independent of particular programming languages and development process.

4. Provide a formal basis for understanding the modeling language.

5. Encourage the growth of the OO tools market.

6. Support higher level development concepts.

7. Integrate best practices and methodologies.

4.2.3 Architectural views and diagrams of the UML

The UML Meta model elements are organized into diagrams. Different diagrams are used

for different purposes depending on the angle from which you are viewing the

system. The different views are called “architectural views”. Architectural views

facilitate the organization of knowledge, and diagrams enable the communication of

knowledge. Then knowledge itself is within the model or set of models that focuses

on the problem and solution. The architectural views and their diagrams are

summarized below:

25

o The “user model view” encompasses a problem and solution from the

preservative of those individuals whose problem the solution addresses. The

view presents the goals and objectives of the problem owners and their

requirements of the solution. This view is composed of “use case diagrams”.

These diagrams describe the functionality provided by a system to external

interactors. These diagrams contain actors, use cases, and their relationships.

o The “Structural model view” encompasses the static, or structural, aspects of

a problem and solution. This view is also known as the static or logical

view. This view is composed of the following diagrams.

o “Class diagrams” describe the static structure of a system, or how it is

declared rather than how it behaves. These diagrams contain classes and

associations.

o “Object diagrams” describe the static structure of a system at a particular

time during its life. These diagrams contain objects and links.

“Sequence diagrams” render the specification of behavior. These diagrams describes

the behavior provided by a system to interactions. These diagrams contain classes

that exchange messages with in an interaction arranged in time sequence. In generic

form, These diagrams describe a set of message exchange sequences among a

set of classes. In instance form(scenarios), these diagrams describe one actual

message exchange sequence among objects of those classes.

26

“Collaboration diagrams” render how behavior is realized by components with

in a system. These diagrams contain classes, associations, and their message

exchanges with in a collaboration to accomplish a purpose. In generic form, these

diagrams describe a set of classes and associations involved in message

exchange sequences. In instance form(scenarios), these diagrams describe a set of

objects of those classes links confirming to the associations, and one actual

message exchange sequence that inconsistent with the generic form and uses

those objects and links.

o “State chart diagrams” render the states and responses of a class participating in

behavior, and the life cycle of an object. These diagrams describe the behavior of

a class in response to external stimuli.

o “Activity diagrams” render the activities of a class participating in behavior. These

diagrams describe the behavior of a class in response to internal processing

rather than external events. Activity diagrams describe the processing activities with

in a class.

o The “Implementation model view ”encompasses” the structural and behavioral

aspects of the solution’s realization. This view is also known as the component

or development view and is composed of “component diagrams”. These diagrams

describe the organization of and dependencies among software implementation

components. These diagrams contain components and their relationships.

4.2.4 UML DIAGRAMS

Every complex system is best approached through a small set of nearly

independent views of a model; no single viewer is sufficient. Every model may

be expressed at different levels of fidelity. The best models are connected to reality.

The UML defines nine graphical diagrams.

7.TESTING

7.1 Introduction

Testing is the process of detecting errors for which the required open web application

secure employment portal specifications stated. Testing performs a very critical role for quality

assurance and for ensuring the reliability of software. The results of testing are used later on

during the software maintenance.

The aim of testing is often used to demonstrate that a program works by showing that it

has no errors. The basic purpose of testing phase is to detect the errors that may be present in the

program. Hence one should not start testing with the intent of showing that a program works, but

the intent should be to show that a program doesn’t work. The main objective of testing is to

uncover an error in systematic way with minimum effort and time.

7.2 Levels of testing

In order to uncover the errors present in different phases the different levels of testing

are:

System Testing

Function testing

The different types of testing are:

Unit testing

Link testing

60

7.2.1 Unit testing

This test focuses on verification effort on the smallest unit of software module. Using the

detailed design and the process specifications testing is done to uncover errors within the

boundary of the module. All the modules must be successful in the unit test before the start of the

integration testing begins.

In this project each service is a module like Login, Forms etc. Each module has to be tested by

giving different sets of inputs. The inputs are validated when accepting from user.

7.2.2 Integration testing

After the unit testing the integration of modules ahs to be done and then integration

testing can be done. The goal here is to see if modules can be integrated properly, the emphasis

being on testing interfaces between different modules.

7.2.3 System Testing

In the system testing the entire web portal is tested according the software requirement

specifications document.

7.2.4 Acceptance testing:

The acceptance testing is performed with realistic data of the client, which focus on the

external behavior of the system; the internal logic of the program is emphasized.

Software testing is a critical element of software quality assurance and represents the

ultimate review of specification, design and coding. Testing is the exposure of the system to trial

input to see whether it produces correct output.

7.2.5 Testing Phases:

Software testing phases include the following:

Test activities are determined and test data selected.

The test is conducted and test results are compared with the expected results.
