System Development
System is the computerized solution for a set of
Problem of an organization or a group of persons.
Its development is divided mainly into four phases;
A. Analysis
B. Design
C. Coding
D. Testing
& Maintenance
(A) Analysis
This is the first Phase in which following major
tasks are done.
1. Meeting with Client.
2. Finding all existing
problems.
3. Selecting subset of
problem that can be solved through computer.
(B) Design Phase
In this phase we deal with following Task are
performed here;
1. Designing of Algorithms
and flow Charts.
2. Determination of inputs,
procedures, filing method and outputs.
(C) Coding
It is simply the typing of source program in a
Selected IDE.
(D) Testing & Maintenance
In testing we check for verification and validation of
program. Verification is the functionality check whether the program is running
or not validation is the achievement of desired level of accuracy and
precision. In Maintenance we perform following tasks;
1. Delivery of system to
client.
2. Software/Hardware Changes
are made.
3. Training of end users.
4. Away of doing a tasks.
