Introduction to Cohesion
Cohesion is the extension of the information hiding concept. Cohesion refers to the internal glue with which a module is constructed. It is the concept that tries to capture the intra module bond. The intra module bond refers to strengthen the bond between elements of the same module by maximizing the relationship between them. So this bond tells how closely the elements of a module are related to each other.
Cohesion of a module represents how tightly bonds of the internal elements of a module have made with each other. A module is cohesive if all elements of the module are directed toward and essential for performing the same task. So a cohesive module performs a single task within a software procedure, requiring little interaction with procedures being performed in other parts of a program.
Ideally, a cohesive module should do just one thing. In cohesion of a module the designer must have a idea about whether the different elements of a module belong to the same module. cohesion and coupling are closely related, usually in practice the greater the cohesion of each module in the system the lower the coupling between modules is , so the more cohesive a module the more related are the internal parts of module to each other and its overall purpose.
Cohesion may be represented as a spectrum as shown in fig 5.13, the scale for cohesion is nonlinear that is low end cohesiveness is worse and high end is best. Generally, the high cohesion is wanted but the midrange of the spectrum in often acceptable so the low levels of cohesion should be avoided when modules are designed. Cohesion of a modules is considered when the highest level of cohesion applicable to all elements in the module.

It can be seen that there are total seven levels of cohesion:
1. Coincidental Cohesion
2. Logical Cohesion
3. Temporal Cohesion
4. Procedural Cohesion
5. Communicational Cohesion
6. Sequential Cohesion
7. Functional Cohesion
