Note

This view focuses on the Functional requirements of the system, usually involving the objects of the system, from these object the UML class diagram can be created to illustrate the view.

A class diagram establishes the vocabulary of the problem and the resulting system, by defining all of the classes of the system, it becomes easier to understand the key abstractions and terminology.

Class diagrams are also useful to specify database schemes, the diagrams makes it easier to see how classes interact and how data should relate to each other in a database.

Another important UML diagram related to the logical view is the state diagram which also involves objects and classes of the system.
