Cohesion serves to determine how many of the elements within a module are related to each other. A module with low cohesion, not dedicated to a single task, causes complexity and difficult configurability.
Types of cohesions listed from strongest to weakest:
Functional: Module performs one action or achieves a single goal.
Informational: Module performs several actions with independent submodules for each.
Communicational: Submodules work on the same input data or contributes to the same output.
Procedural: Module performs a series of actions corresponding to steps followed by the product.
Temporal: Module performs a series of actions corresponding to time.
Logical: Logically related submodules but not functionally related.
