When I develop a software for the company I came across a problem.I think I need to have some clarification on that.So I wrote this and if someone has this kind of question then this post will help you.
Ok let's start my question,
I will explain from the beginning of my question,
After I draw the Use case diagram then I start to draw the class diagram of my system, after that make the ER diagram for my system.
after all I tried to implement this system in my VS IDE.I create the SQL table structure according with My ER diagram which I already drew.after that I make Object relational mapping for sql.
Then my problem arose.My class diagram and the ORM class diagram both are alike.(not 100%).So I am thinking that "am I do the class diagram repeated?".because ORM class done most of the things for me so why do I implement other class diagrams ?(which is my class diagram when I start of design the software)
I am sure I have miss concept something somewhere and if you feel that you can help me highly appreciate.
