Information development-phases

1. INFORMATION DEVELOPMENT PHASES
Phases Activity
I. Problem Analysis
Phase
-Programmer will interview client what they need
-Programmer get the information of input, process and output
-Programmer will refer to the website in internet or book or
expert person
-Programmer will choose the suitable programming language to
solve the problem
II. Program Design
Phase
- In program design, there are three popular tools used:
i) Top-down design model - This top-down model consists
of three modules, namely input module, process module
and output module
ii) Pseudocode - the programmer writes the pseudo code
for the program based on the top-down design model
iii) Flow chart- the programmer draws the flow chart that
shows the data flow of the program.
- Choossing and design the user interface
III. Coding Phase - Programmer translate the pseudocode to programming
language
- Key in the programming language into the computer
IV. Testing and
debugging
- Programmer test the program to search for any error
- Programmer will debug if there is any error.
V. Documentation - Programmer write the purpose of the program
- Programmer write the guideline on how to use the program to
the client
- Programmer write the type of input and expected output
