Explain the Object-oriented decomposition
Object-oriented decomposition targets at identifying individual sovereign objects that encapsulate both a state and certain behaviour. Each main components of the system is known as subsystem. Then communication between these objects leads to the required solutions. Decomposition of the system in function-data model (SAD) and the object oriented decomposition are given below. Although solutions help deal with complexity, you have reasons to believe that an object-oriented decomposition is favourable since, the object-oriented approach provides for a semantically richer framework which leads to decompositions which are more closely related to entities from real world. Moreover, the recognition of abstractions supports heaving solutions to be reused and object-oriented approach supports evolution of systems better, as those ideas that are more likely to change can be hidden within objects.
Natural Join : It is the similar like Equi join except one of the duplicate columns is removed in the result table. The natural join is the most usually used form of join operation
Views A view is like a window by which data from tables can be changed or viewed. The table on which a view is based is known as Base table. The view is stored as a SELECT stat
Two-way Associations Mostly, associations are travel in both directions, although not usually with same frequency. There are three approaches for the implementation. In
What is the major advantage of object-oriented programming paradigm? The ability to modify the explanation of an object without affecting the rest of the system is the main adv
