Q. Explain about Data coupling?
The dependency among module A and B is said to be data coupled if their dependency is based on the fact they communicate by merely passing of data. Other than communicating by data the two modules are independent. A good strategy is to make sure that no module communication contains tramp data only the necessary data is passed. Students address, name, course are example of tramp data that are unnecessarily communicated between modules. By making sure that modules communicate only necessary data module dependency is minimized.
