➡ Cohesion Cohesion is a measure of the relative functional strength of a module.
➡ Types of cohesion :
➡ Coincidentally cohesive(LOW) a module that performs a set of tasks that relate to each other loosely, if at all. Such modules are termed coincidentally cohesive.
➡ Logically cohesive A module that performs tasks that are related logically (e.g., a module that produces all output regardless of type) is logically cohesive.
➡ Temporal cohesion When a module contains tasks that are related by the fact that all must be executed with the same span of time, the module exhibits temporal cohesion
➡ Procedural cohesion When processing elements of a module are related and must be executed in a specific order, procedural cohesion exists.
➡ Communicational cohesion When all processing elements concentrate on one area of a data structure, communicational cohesion is present.
➡ Sequential Cohesion If the function of the module forms part of sequence, where the output of one function is the input to another function.
➡ Functional Cohesion(HIGH): In this, different elements of the module cooperate with each other to achieve a single function.
