Cohesion Categories
A
module that performs more than one function and these are only related
logically.
Example
A module performs all of the master file access operations. It reads, adds, updates and deletes master file records under parameter control, and is has the following interface.
call
employee(function, status, file_record)
Advantages
 | All of the functions operating on
the master file are in one module. |
| Uses only one entry-point for all modules, making dynamic loading in most environments possible. |
Disadvantages
| Changes to this module may cause
a ripple effect necessitating the change of modules that are not using the
new functionality. |
| Control routing requires coding,
testing and maintenance.
