It includes the requirements for the program to be useful, reliable and maintainance, make them reliable and understandable

1. GOOD
PROGRAMMING
PRACTICE

2. GOOD DESIGN AND PROGRAMMING
PRACTICE INCLUDES
 Styles and format
 Structured programming
 Coupling and Cohension
 Documentation and source control
 Scheduling

3. 1. STYLES AND FORMAT
 Pseudocode before program.
 Add appropriate comments : Readable and clear, concise, correct.
 Name variables properly. Minimize use of global variables.
 Don’t pass pointer.
 Include brief header before each routine including objectives and summary.

4. 2. STRUCTURED PROGRAMMING
 Establish framework for generating code that is more readable, reliable and
maintainable.
 Framework based on clearly defined modules or procedures.
 Structured programming encourages the installation and testing of one module
at a time to simplify the verification of the software.

5. 3. COUPLING AND COHESION
 coupling is the degree of interdependence between software modules; a
measure of how closely connected two routines or modules are
 Modules should have minimum Communication or coupling.
 Coupling types:
 Loose coupling(modules interact with one another through a simple and stable
interface)
 Tight coupling(A module modifies or relies on the interval workings of another
module).
 Cohesion measures the strength of relationship between pieces of functionality
within a given module.
 A cohesive module performs a single task.
 Modules should have maximum cohesion.

6. 4. DOCUMENTATION AND SOURCE
CONTROL
 Documentation describes the overall system function.
 Backup file sources to prevent loss of data and code.
 Back up source files: disks, CD, tape drivers.
 Store multiple copies in separate location.
 File storage is cheap but reconstructing lost data is expensive and impossible.

7. 5. Scheduling
 It estimates software development time.
 Should record all efforts expended in current jobs to estimate future job.
 Timing of meeting, planning, designing, debugging testing should be properly
planned.
