1.3 Purpose of the Project

Goals and Objectives of the project

Purpose ofCollege Portal is to manage the college resources more efficiently. College Portal web and LAN base application for college staff and student to use

various functionality with optimum use of resources.

As name suggest College Resource is contain various functionality that handled bypaper work as now some of them been implemented in our project by us.

Provides fast and efficient way to store and search the data. Subject wise average attendance can be generated by filtering the date range and also can

have hard copy of that report.

Student records can be filtered easily. Alumni student can be grouped easily by sending mail to authorized student. There is so many good objectives available within this project which never been realistic

in past. (As per our knowledge).

1.4 Scope of the Project

Software Scope describes the data and control to be processed, function, performance,

Constraints, interface and reliability.

FUNCTIONSFunctions described in statement of the scope are evaluated and in some cases refined to

provide more details prior to the beginning of the estimation.

PERFORMANCEPerformance consideration encompasses processing and response time consideration.

CONSTRAINTSConstraints identify limit placed on the software by external hardware, available memory

or other existing system.

INTERFACEInterface includes the hardware that executes the software, software that already exists,

people that make use of the software and procedures that precede or succeed the software

as sequential series of operation.

RELIABILITYIt measures at how many point the system fails. The lesser the failure, the more is the

reliable system. The system we have built is suitable for todays fast life as people dontget time to spend on things that are less essential.

The system built is advantageous in many ways, after studying the requirements of thesystem and knowing the problems faced by the user the scope of proposed system is as

follows.

For the marketing of the current system company appoints the executives through thelimited states. So the scope of the current system is lower and now this system become

online and LAN based as well as transparent by this project so the scope of this

application will be higher.

1.5 Project Deliverable (What it can do?)

It helps the student to check the attendance reports. It will also provide the student toshare his/her knowledge through college educational forum.

College Portal can be used by faculty by updating student attendance day by day andto remain in touch with past students through alumni module.

Attendance report is the key functionality of this project and we can generate subject wiseaverage attendance report of any student.

The Project Deliverables are results that are delivered to the customer. Below is a list of the

deliverables for this Project:

What it can't do?

This project cannot generate attendance report of last semester attendance records because

database would be refreshed after every semester as every semester contains approximate 50000

records in the database.

2.PROJECT PLANNING AND SCHEDULING2.1Process Model


7/66

College Portal


The software development model, adopted for the proposed system, is waterfall model

(Iterative model).

2.1.1 Project Plan

Figure 2.1 Iterative Waterfall Model

Reason for choosing the Waterfall Model:

Waterfall model stipulates that the requirements should be completely specify before the rest of

the system development is preceded. In the proposed system, the requirements are fixed and

known beforehand and hence this model is suitable and adopted for the development of the

proposed system.

The systems services constraints and goals are established by consultation with system users.

They are then defined in a manner is understandable by both users and developers. The system

design process partitions the requirements to either hardware or software system. It establishes

overall system architecture. Software design involves representing the software system functions

in a form that may be transformed into one or more executable programs.

Analysis Phase

This phase involves detailed study of the system using different tools like OMT and UML. First

Using conventional requirement collection and engineering technique user and system

requirements are explored. This gives the very detailed knowledge of the system. OMT includes

Object Modeling, Dynamic Modeling and Function Modeling.

Design Phase

As conventional design method and according to OMT, as first step of design Subsystems of the

system are identified. This phase also includes Architecture design, Deployment Design, File

system Structure design and UI design.

Implementation Phase

Implementation phase includes development of UI components, creating prototypes of each core

classes, development of core classes, UI development and remote service creation.

Testing Phase

In testing phase each method of the classes are checked during development phase as unit

testing. Then each class is integrated and they are tested for integration testing. Ultimately test

cases are tested to ensure that there are no bugs in the code.*/

OMT

It is primarily used by system and software developers supporting full life-cycle development,

targeting object-oriented implementations. Because of its simple core notation, OMT has proven

easy to understand, to draw, and to use. It continues to be successful in many application

domains: telecommunication, transportation, compilers, etc. The popular Object Modeling

Technique (OMT) has been used in many real-world problems.

Key Benefit:

The object-oriented paradigm using the OMT spans the entire development process, so there is

no need to transform from one type of model to another.

2.4 Risk Management

2.4.1 Risk Identification

Risk identification is a systematic attempt to specify threats to the projects plan by

identifying known and predictable risks. Risks are about events that, when triggered,

cause problem. Hence risk identification can start with the source of problems or the

problem itself.

There are three main categories of risks which can affect a software project:

Project Risks Technical Risks Business Risks

Project Risks:

Project risks concern various forms of budgetary, schedule, personnel, resource and customer

related problems.

Miscommunication: It leads to misunderstanding, delay, frustration, lack ofcoordination amongst the team members and client.

Time shortage: It leads to delay in the delivery of the product.

Personal conflicts between team members: It leads to unnecessary delay in eachand every phase of software cycle and loss of direction.

Illness or absence of team members: Absence of a team member increases the loadof the project on other team members.

Lack of expertise to fulfill certain tasks: Lack of knowledge in some areas leads toinsignificant delay.


11/66

College Portal


Technical Advisor not available when needed: Due to the absence of a technicaladvisor there was a delay in understanding the database .

Unavailability of customerTechnical Risks:

Technical risks concern potential design, implementation, interfacing, and testing and

maintenance problems.

Too many planned features lead to infeasible design Design errors: Due to lack of experience design errors are bound to happen.

The customer changes the requirements: The scope of our project keeps changingas per users requirements

The customer disapproves of the prototype: The customer may find the developedprototype unsuitable to his requirements

Business Risks:

Business risks threaten the viability of the software to be built. Business risks often jeopardize

the project or the product.

Market risk: Building a excellent product or system that no one really wants. Strategic risk: Building a product that no longer fits into the overall business strategy

for the company.

Management risk: Losing the support of senior management due to a change infocus or a change in people.

Product is not put in service2.4.2 Risk Analysis

Personnel Shortfalls:They may cause the developmental delays and would cause a change in the working

strategy due to developmental dependencies of the functional modules.


12/66

College Portal


Unrealistic Schedule:It may cause the developers to give unrealistic commitments to the users and so lose

their faith when the deliverables are not produced as per schedule.

Developing wrong Software functions:It can be caused due to wrong requirement analysis or wrong programming method

used to automate the requirements. It may cause the system to fail and not be

implemented at all.

Developing wrong User Interface:It may be caused due to lack of user acceptance and user involvement duringdevelopment.

The probability of the risk might be assessed as very low (75%).

It involves methods that accept the loss when risk occurs. Risk retention is a viable strategy

for small risks where the cost of insuring against the risk would be greater over time than the

total losses sustained. All risks that are not avoided or transferred are retained by default

Risk Transfer:

It involves method, which causes another party to accept the risk, typically by constructs or

by hedging.

3.2Hardware And Software RequirementsHardware Requirements

The Online System that we have built requires some specific hardware configuration. I have

mentioned the basic minimum hardware recommendations to run the system adequately. Any

higher configuration hardware would only add to the performance of the system. The minimum

hardware requirements to run the system properly are as under.

Pentium 4 with 1.4 GHz processor 40 GB Hard Disk 512 DDR RAM Network Card / Network Connection

Software Requirements

Server Side

Operating System: Microsoft Windows(XP and onwards) Web Server: Internet Information Services (IIS) Server Database: MY SQL

Client Side Operating System: Microsoft Windows XP Web Browser: Fire Fox Mozilla / Internet Explorer 5.0

Technology Used for Development:

FrontEnd Tool: ASP.Net with C#, AJAX Bac kEnd Tool: SQL Server 2000

Operating System:

Windows Professional Edition with Service Pack3.3 Constraints

A constraint is anything that prevents the system from achieving more of its goal.

Hardware Limitation.


18/66

College Portal


It requires minimum 256MB RAM to be loaded or run. It requires IIS to browse the

application.

Interfaces to Other Application.Since it is a standalone application it cannot be interfaced with other applications as such.

Higher Order Language Requirements.Since the application has been created in JSP (Java Server Page) which is a successor of

C/C++, it gets easily dissolved with any operating system since C/C++ constraints for all

operating systems are the same.

Reliability Requirements.Since the application is almost error- free, the reliability of the system is pretty high.

Even in case of natural calamities or power failure or connection failure, the application

is not affected as data remains secured in the corresponding database.

Criticality of Application.Criticality of the application lies in the fact that when any field in any one of the six

modules is empty then that particular record is not added or updated in the database. Even

without proper name & password the administrator cannot access the application.

College Portal


4. ESTIMATION

4.1 Effort Estimation

Project Estimation proper evaluation of the system and to get the estimation of the

project, it was needed to do some metrics calculation for this project. Software project metrics


20/66

College Portal


are the way to do this task efficiently. Project metrics allow knowing the size and complexity of

the project and helping us on the planning and cost estimation.

For this project, function-oriented metrics were used to get the size of the project at the

abstract level (without taking the language in consideration). For that purpose, Function Points

(FP) was used.

Function Points can be counted using the following information domains:

Number of external inputs (EIs)inputs given by a user or another system. Number of external outputs (EOs) outputs derived within the system or given to

another system.

Number of external inquiries (EQs) as an online input that results in generation ofsome immediate software response in the form of an on-line output.

Number of internal logical files (ILFs)logical grouping of data that resideswithin the applications boundary and is maintained via external inputs.

Number of external interfaces files (EIFs) - logical grouping of data that residesexternal to the application but provides data that may be of use to the application.

5.1 Study of Current System

In the past before site is organized following difficulties are coming towards user.

First LookIn current system clerks are doing paper work to maintain students records and employees

records and that record may be frequently used in any terms, Like student records used to search

any student or to update the student attendance day by day and employee records can be

frequently used in this environment.

Role Based Access Control (HOD, Admin, Lecturer and Student have diff access) Superior Technology for Faster and Secured Access

Friendly FeaturesSome of the friendly features of this software are as follows:

Towards Paperless College System Efficient Monitoring of Activities Automated Assessment Features To Eliminate Manual Scheduling Errors Promotes Effective Utilization of Resources Facility To Track Realization & Growth Tracking of Interest of People for the Upcoming Activities.

ExtendibilityAfter implementing the whole system, if any type of suggestion and any new ideas

are allowed. According to that it is possible to extend the system for more convenient.

User FriendlinessSome of the features that make the software user friendly are as follows:

User friendly design Easy to access all the accessible modules.

5.4 Feasibility Study

In the history of College Portal it happened first time to use this kind of web an Lan based

application and its feasible to implement within a less time and money.

5.4.1 Operational FeasibilityPerformance

Our system provides adequate throughout and its response time is very quick.

Because when any user sees the application for searching the data, it will search

form the database and display the output.

Information

The system provides records to end users with timely, accurate and

usefully formatted information. When any user or administrator wants the

information about system, he or she will just log into system. And get their desire

information.


28/66

College Portal


Economy

No we are not jumping into economic feasibility. The question here is

does the system offer adequate service level & capacity reduce the burden of

manual work of the college.

Efficiency

Does the system make maximum use of available resources including

Manual Work of Administrator, time, and flows of forums, minimum processing

delays & the like?

In the matter of efficiency, our system is totally computerized, so no need

for any person to explain anything regarding our system, and its very easy to

understand as well as operate.

Each and every information is given very briefly and well known to user

so user is able to do the work without any Administrators help. Here also only few

persons are required for moderating and controlling the system, so with the help

of very less human resource and manual work system will work.

All the forms are well designed as well as developed so user can easily

deal with system like every form is designed as per the lecturers requirements.

5.4.2 Technical FeasibilityIt is a measure of practically of a specific technical solution and the

availability of technical resource and expertise.

The analyst must find out whether current technical resources, which are

available in the system is capable of handling the users requirements or not. If

not, then the analyst with the help of developers should confirm whether the

technology is available and capable or not.

As per the availability of the technical resources we could make this

project of student and attendance management.

Q-1 Do we currently posses the necessary technology?

Ans : Yes,


29/66

College Portal


The technology & software that we are going to use are available with us.

The technology which we have used is easily available in the market today.

Q-2 Do we have necessary technical expertise?

Ans : Yes,

We do have necessary technical expertise so that development would be

compatible with the schedule. But certain kind of training is required for the

particular technology but it will not make an adverse effect on the development

schedule.

Factor considering

Here we have to consider those tools, which will be requiring for developing theproject.

The tools which are available and the tools, which will be required, have to takein account. As far as basic knowledge is concerned we have studied we have basic knowledge

of C# and SQL server. Various technical books, e-books etc are available.

Dealing with database is the main issues in our system. Using SQL server asbackend provided this functionality. But we have used MY SQL.

5.4.3 Schedule Feasibility:Schedule feasibility corresponds to whether sufficient time is available to

complete the project.

Factor considered

Schedule of the project was around 3 months Time by which the project has to be completed. Reporting must be completed within this time period.

By considering all above factors it was decided that we have sufficient

time and we decide to start the project. By marinating the schedule we were able

to complete the project on time.

5.4.4 Economic Feasibility


30/66

College Portal


For declaring that the system is economically feasible, the benefits obtained from

the system we have to be rated against the cost incurred to actually develop the

system. The benefits must equal or below the cost for development.

The basic resources to consider are:

Management time. Time spent by the system analysis team. Cost of doing full system study. Estimated cost of hardware. Estimated cost of software and /or software development.

The following are benefits that would be derived from the proposed system:-

The application is developed using C# and MYSQL server technology.Application does not increase hardware cost as minimal configuration

required for developing code. In this way developing application does notgenerate any overhead costs.

As this application has no overhead in development and installation buteconomically this application will be beneficial to maintain student records.

5.5 Requirements ValidationAs our project is to build a dynamic web site and lan based, there is criteria such as

windows authentication but still some security must be provided in essence of making the

rights of certain entity to be limited to them. Certain validation criteria that are neededlisted below.

In our system, some functionality like view the employee and college records arerestricted to the admin and college employee only. So, we have to apply validation

for the login functionality for the authentication.

Our system generates the student attendance report from the web services as per theusers search criteria. So to produce the best match we have to apply validations on

the input controls.

In the page of Personal Detail of alumni student, student has to enter his/her contactinformation (Email Id) in order form which he/she get mail when he/she fill that

form our college gave him user name and password to access site. So, we have to

apply validation on the field of Email Id.

5.9 Main Modules of New System

The Main module is used to manage all other modules present in this project and it is

the Heart of our data logger.In our project student registration, employee registration and

fill attendance module can be considered as the main module because other all the

modules like attendance report cannot be work without this module

5.10 Selection of Hardware and Software and Justification

Software

The software selected for the modules are .NET(Asp), MYSQL. This software has been selected for this module for the following reasons: .NET is selected for this module because it supports multiple languages. .NET provides many built in functionality so we choose to develop our project in .NET MYSQL is used as database as it easier to build database in it and connect. MYSQL is used as database, because as stated earlier MYSQL is Open source there is

no need to purchase license for that.

Hardware

PROCESSOR: Pentium IV. RAM : 1GB. MEMORY : 80 GB HDD SPACE.

I have used the above mentioned hardware specification in order to obtainoptimized

performance.

6. TESTING

Errors are more common, more pervasive and more troublesome in software than

with other technologies

Software Testing has a dual function; it is used to establish the presence of defects inprogram and it is used to help judge whether or not the program is usable in practice. Thus

software testing is used for validation and verification, which ensure that software conforms

to its specification and meets the need of the software customer.

Developer resorted Alpha testing, which usually comes in after the basic design of the

program has been completed. The project scientist will look over the program and give

suggestions and ideas to improve or to correct the design. They also report and give ideas to

get rid of around any major problems. There is bound to be a number of bugs after a

program have been created.

Software InspectionAnalyze and check system representations such as the requirements document, design

diagrams and the program source code. They may be applied at all stages of the process.

6.1 Testing Plan

The Testing ProcessDeveloper tests the software process activities such as Design, Implementation,

and Requirement Engineering, because design errors are very costly to repair once

system has been started to operate. Therefore, it is quite obvious to repair them at early

stage of the system. So analysis is the most important process of any project.

Requirements TractabilityAs most interested portion is whether the system is meeting its requirements or

not, for that testing should be planned so that all requirements are individually tested.

Developer checked the output of certain combination of inputs, which gives desirable

results, or not. Strictly stick to your requirements specifications, give you the path to get

desirable results from the system.


46/66

College Portal


Tested ItemsOur tested items are like database object reading/writing, skin object

manipulation, view of containers and skins in different browsers.

Testing ScheduleDeveloper has to test each procedure back-to-back so that errors and omissions can

be found as early as possible. Once the system has been developed.

6.2 Testing Strategy

Unit TestingModule TestingIn this testing individual components and modules are tested to ensure that they operatecorrectly. We had tested each and every module such as login details, upload details, to

maintain information for all the features and finally the generation of the reports. For this

we have checked the database for particular entry for validation.

Integrated TestingThis testing is a systematic technique for constructing the program structure while at the

same time conducting tests to uncover errors associated with interfacing. All the modules

testing in the unit testing are integrated and are tested for their interdependency. This

system mainly works on the integration of all the departments.

Validation Testing - Alpha TestingA customer conducts alpha testing at the developers site. The customer check by

entering the live data. If any errors occur in the system than they directly contact us.

Security TestingThis testing is done to confirm that the software allow only authorized users to access anduse the system. There are two levels of security in this system. We have tested entering

the username and password for all the security levels to show them the information

pertaining to their work only.

Human Factor TestingThe user cannot do anything if after submitting the screen goes blank while the data are

being processed. They may not take the action the analyst wanted or expects instead

responding in unusual ways.

6.3 Testing Methods

Testing methods Involves executing an implementation of the software with test data and

examining the outputs of the software and its operational behavior to check that it is performing

as required.

6.3.1 Statistical Testing

Used to test the programs performance and reliability and to check how it worksunder operational conditions. Tests are reflecting the actual user inputs and their

frequency.

The stages involved in the static analysis for this system are as follows:-

Control flow analysis Unreachable code Unconditional branches into loops Data use analysis Variable used before initialization Variables declared but never used Variables assigned twice but never used between assignments Possible array bound violations Declared variables Interface analysis Parameter type mismatches Parameter number mismatches Non-usage of the results of functions Uncalled functions and procedures

Structural Testing

We have done path testing to exercise every independent execution path through a component or

program. If every independent execution path is executed then all statements in the components

must have been executed at least once.

Integration Testing

After our individual modules were tested out we go to the integrated to create a complete system.

This integration process involves building the system and testing the resultant system for

problems that arise from component interactions.

We have applied top-down strategy to validate high-level components of a system before design

and implementation have been implemented. Because our development process started with

high-level components and we worked down the component hierarchy.

Performance Testing

Performance testing is designed to test the runtime performance of the system within thecontext of the system. These tests were performed as module level as well as system

level. Individual modules were tested for required performance.

In performance testing we counted the processing time and response from the systemwith respect to request.

We also checked out the total-execution time, which takes 10 to 15 seconds for loading.Condition Testing

Condition testing is the test case design method that exercise the conditions contained in a

program module. If the condition is incorrect then, at least one component of the condition is

incorrect. It may include

Boolean variable error String index out of bound error Null pointer assignment Input output connection exception Parsing (conversion) errors Arithmetic expression error


50/66

Interface Testing

Interface testing is integral part on Integration testing. Therefore we checked for

Interface misuse Interface misunderstanding We examined the code to be tested and explicitly list each call to an external component.

In the system, standard tests for GUIs have been performed, which are as follows:-

The position and related labels for all controls were checked. Name of the form is also given appropriately. All menu functions and sub functions were verified for correctness. Validations for all inputs were done. Each menu function was tested, whether it invokes the corresponding functionality

properly.

Pull down controls was verified for proper functionality. Whether the non-editable text control is disabling and it was also Verified that it doesnt

exceed the maximum allowed length.

Whether the system prompts the user with appropriate message as And when invalidinformation is entered.

Stress Testing

Stress testing is to test the system for emergent properties such as performance and reliability.

Performance tests have to be designed to ensure that the system can process its intended load.

Object Testing

Object testing is to test objects as individual components, which are often larger than single

functions. Here following activities have taken place.

Testing the individual operations associated with objects. Testing individual object classes. Testing clusters of object. Testing the object-oriented system.

Reliability of the System

There are three approaches to reliability of the system.

Error Avoidance

Error Avoidance is impossible in any system, as it points to prevention of errors from occurring

in system. In our system, we cannot prevent occurrence of errors because, if user does not call

methods properly and does not input appropriate parameters, we are unable to avoid errors.

Error Detection and Correction

Error Detection corresponds to reorganization of errors when they are encountered. In the

system, developer use alert message to prompt errors to users. We also use try-catch structure to

prompt errors. Alert message shown to users are in well-understood forms. System prompts

various error messages like file does not exist, whenever the user tries to open any other file

instead of image file. However, system does not support correction of errors; it is user's

responsibility to take appropriate action.

Error Tolerance

Error Tolerance refers to reorganization of errors when they occur, but enables system to keep

running through degraded system. In system will never shutdown automatically due to errors, but

it is possible that because of errors it may not work efficiently. For example, if invalid image is

given then system will prompt error and it will not shut down. Furthermore, if user does not add

image file, in that case, that layer is not displayed nor activated and any further operations are

not done.

SUMMARY


61/66

College Portal


8. SUMMARY

Our project wasto create a COLLEGE PORTAL which could be useful for college.This

portal has many features such as good interactivity, ease of use, proper GUI, simple navigation,

effective and accurate results and good security. The main objective is to build a system thatassists the end user in finding aany type of record he wants provided he has proper authority. For

this system, there are 4 types of users: they are Admin,Staff,Student and Guest users.

8.1Overview

This project aims to eliminate extra work that is associated with finding a company to

develop a software project. Previously the customers had to make a field study about the

software companies that would build their software product and have to perform a lot of paper

work. Now they can simply post a software proposal and interested software companies bid on

those software proposals. This way the interaction between the customers and development

companies will become easy and simple. This is an online bidding system consisting of mainly

three types of users: namely customers, software development companies and administrator. The

project also allows software developers and customers to give feedback to each other for a

particular project.This website helps the customers and software developers to interact easily and

share information effectively in a secured manner. It works as a bridge between the customers

and software developers.

8.2Specification and Project Plan

8.2.1 Requirements specification

The software requirements specification document contained information about the

project such as objectives and goals of developing the software product. It also contained the

information about the target environment, various types of requirements such as functional, non-

functional and domain requirements. Moreover, the requirements document also had some

details about the users of the system, major functions performed by the system as well as the

risks associated with the system. And finally the deliverables of the system. More information

can be obtained from the software requirements specification document.

8.2.2 Project Plan document

The project plan document contained information about the project, process model used

for building the project, team organization, deliverables of the project and risks associated with

the project. It also focuses on the project schedule, project estimates, control plan and project

resources. For more information on project plan see project plan document.

Team

Overview

The members of the team were:

Madhu Shukla. Viral Parekh. Dipalee Rathod. Manisha Valera.

Team Structure

Our team is a Democratic Decentralized (DD) team. Instead of having a team leader, each

member in the team was responsible for some specific task. The decisions were made by

conducting meetings and discussions. The team as a whole was accountable for the

outcomes of its decisions and actions. All the members of the team performed some

specific functions such as requirements gathering and reviews were done by all the team

members while you can see the details of the tasks that each person performed from the

task sheet.

Advantages

As our team structure was Democratic Decentralized (DD) we did not have any team

leader. All the members took the decisions by reaching a consensus. No decision wasforced on anyone and hence there no clashes for anything. There were no ego problems

and the working in the team went off very smoothly. Everyone got equal opportunity to

share and implement their ideas. No member of the team faced any problem working

with others and everything went off very smoothly.

Disadvantages

The only problem we faced sometimes was staying on schedule. So if there was a team

leader, then he would force us to finish the work on a specific date so that we do

everything on time. Also sometimes we had a hard time to decide what we should do next

and in what time, so this was an issue.

College Portal


Doing things differently

We could have developed system with different suited model and as following

centralized structure to comple it earlier than the time taken. Also it could be

implemented on different environment than .NET to make it cost effective using OPEN

SOURCE software.

Process

Overview

We used Iterative Model. So With incremental yield is intended that all requirements to

be fully described. Then the system iterative phases. The first definition phase study is

performed once. Work is done in phases. And also increments of the product can be madewith enhance features as time passes.

Advantages

Risks can be better managed by smaller pieces to be developed. Bottlenecks are so quickto light.

Complex systems are clearer and less complex to implement it step by step to acomprehensive income working without the need of a complete design is created.

At the end of each iteration, a useful product, even if the development is discontinuedput. In a linear method would often never made use perch.

Changes in organization can be quickly incorporated into the development process.Disadvantages

There are obvious disadvantages. Some disadvantages:

Because during the development process needs to be adapted and refined, it may be that

the original purpose fades. It can happen that it continues to change and it never finished.

This is called Scope Creep.

Project managers who are accustomed to linear development can be confused by thestrong dynamics.

The rapid development has the potential to draw a bill on the organization and resourcesof the great dynamics.

Inexperience with the way of working can lead to misunderstandings anddisappointments.


64/66

College Portal


Conclusion

We used iterative model and hence we needed to develop the requirement on hand as a core

product. Team structure used was Democratic Decentralized which again benefited us as

member with expertise in different field leaded at different phase of time. Also further

development can be made in the system it can be enhanced as well as can be converted as web

based system.

Future Implementation

1) Message service is most accentual services so it can be added in future for circular andother curriculum activities.

2) College Portal can be converted into a web based application for fully web basedfunctionality.

3) It can be used in Online Examination also.
