What are the outputs of the logical design?Logical design can have many outputs, some of which might be:
a) E-R Diagrams:
It is known as entity relationship diagram. They are a visual representation of data that describes how data is related to each other.
b) Class Diagrams:
It is a static diagram which represents the static view of the application. It describes the attributes and operations of a class and also the constraints imposed on the system.
c) State-Transition diagrams:
They are used to define a machine that has a number of states. They give an explicit and formal definition of behaviour.
d) Sequence diagrams:
It is an interaction diagram which shows how the processes operate with one another in an order. It shows the object interactions arranged in a time sequence.
e) Object interaction diagrams:
It is used to describe some type of interactions among the different elements of the model. It is a part of dynamic behaviour of the system.
