The system flow chart:
- Represents various computer programs, files, databases associated with manual processing that make up a complete system
The structure chart
- Describes functions and sub functions of each part of the system, relationship between modules of a computer
- Each module performs a specific function
Module algorithm deisng: Pseudocode
- Descrobes internal logic of of modules
- Syntax should mirror development code
- Three types of control statements used in structured programming:
- sequence: sequence of executable statements
- decision: if-then-else logic
- iteration- do-until or do-while
Three-Layer Design
- View layer
- Business logic layer
