The Logical Design phase During this process, we define the structure of various logical entities which will be forming the solution and the behavior of those to interact with each other. Process to create the logical design is as follows:

1 Identify Business Objects: The objects which either provide some kind of service or use some service or hold data which is useful for the business processes are the candidate business objects. Finalized business objects will be modeled as Classes.

2 Identify the services that will be offered by these business objects. These services later on will be modeled as Methods of the classes.

3Identify attributes of the business objects. Attributes will hold the data and will be modeled as Fields and Properties of the classes.

Class Diagram: This is a logical class diagram which provides the structure of elements on which the behavior of the system can be based and a solution can be built. On the logical diagram we can model classes, interfaces, enumerations, packages and relations between all of them. These relations can be of the types – Association, Inheritance, Dependency and Package Import. All of these are available in the toolbox.
Interfaces can be shown either as a box with full details or just a lollypop attached to a class to indicate that the specific class implements that interface. Classes and Interfaces will have the attributes and operations. If we attach an interface to a class and then add members to the interface then those members will automatically appear in the implementation class

So, the conclusion is frequently the architect using this diagram to shown what is the entity object need to be explained and become the conceptual architect and..it’s looks like ORM (Object Relational Mapping Diagram ) Modelling .
so maybe next time we discuss further about this..bye all…
