SDLC :: System Development Life Cycle

 System Analysis & Design is done through a process which is called System Development Life Cycle. SDLC is a set of activities that analysts, designers and users carry out to develop and implement an Information system. This consists of the following

A. Preliminary Investigation Feasibility Study:

 
Technical feasibility : The equipments/ Hardware and Software required to implement the project successfully is studied. The cost of these items vis-à-vis available resources and personnel are looked into.
Operational feasibility : Will the system be used if it is developed and implemented? Will there be resistance from users that will undermine the possible application benefits?
These things are studied t know the feasibility of the proposed Project.

B. Determination of System Requirements

The Study of the Proposed System :
The proposed system is to be designed for the BCA final semester students, so that they can know about the status of their project, its approval or rejection status and date of viva in case their project is approved.
The steps involved are

a) Submission of Project Proposal to SOCIS, IGNOU, New Delhi.
b) In a month's time, communication from SOCIS about its Approval. In case it is disapproved, student will be informed about the reason for its disapproval.
c) Communication to Student - Approval of Project Proposal .
d) Submission of Project Report to SR&E, IGNOU, New Delhi.
e) Communication to the student about the schedule of project viva.
f) Evaluation and Viva - conducted by SOCIS.

g) Results & Grade Card sent to Students by SR & E Division.

The System Requirement
The requirement is that IGNOU can attend to the queries of the student regarding the receipt of project proposal, Approval/Disapproval of Project proposal, Receipt of Project Report and Schedule of Project Viva. So generation of Database of student, Data Handling & creation of Link between student and IGNOU is to be done.


Information Collection/Gathering
Students, SOCIS & SR&E Divn all three involved in information interchange as seen below. The information is gathered from all these three to know the process involved.


The System Solution

Post Implementation review is done with each department which are involved in this process. New suggestions to be implemented in the system are discussed and overall working pattern are decided here.

C. Design of System

It involves the details that clearly describe how a system will meet the requirements identified during system analysis. This is also a called stage of logic design.
D. Development of Software
Development of new software or use of already available package is decided here according to the specification decided.

D. Development of Software

Development of new software or use of already available package is decided here according to the specification decided.

E. System Testing

During system testing, the system is used experimentally to ensure that the software for the SOCIS, IGNOU does not fail. Special input data may tested.

F. Implementation, evaluation and maintenance.

The system personnel will check out and will put new equipments into use, train users, install the new application and will construct new files of data like student database files, project synopsis database files, application/software database files etc. needed to be used. And Evaluation is performed to know the merits and demerits of the software, which are subsequently rectified.
