    - Data coupling is the most desirable form of coupling.
    - It is passed to a module to begin the processing of that module or it can be return to the calling module.
    - It occurs when modules share data, for e.g. parameters.

    Control coupling - This module controls the flow of another module by passing the information on what-to-do flag.

    This may lead to changing the way of module that reads a record because the module does not need to modified the field.

    When one component passes parameters to control the activity of another component, we say that there is a control coupling between the two module.
