    Coupling
    - The physical connections between elements of the OO design represent coupling within an OO system.

    - Example: The number of collaborations between classes or the number of messages passed between objects.

    Cohesion
    - It refers to the degree to which the elements of a module belong together.

    - Thus, cohesion measures the strength of relationship between pieces of functionality within a given module.

    - For example, in highly cohesive systems functionality is strongly related.
