Question
Why is it required to have an abstraction layer in UML?
Answers
Abstraction allows the identification of key domain objects to match the user requirements. Abstraction keeps all the code at one place allow the physical design to be given at later stage. Abstraction also allows the structure to be maintained as it is and the alternation won't affect the overall system if changes are imposed on the system as whole. It keeps the data of relationship between other objects and their associations with each other. The association has to be maintained such that one's affect won't have any impact on anothe entity that is used in UML. It keeps the data and programs in the same form and keeps their meaning also intact. It hides the implementation details from the users. It reduces the load from the programmer and allow more time to implement the system in complete.   Your Comment
