Hi Osama,

Sorry for my late response. In our Visual Paradigm for UML (VP-UML)/Smart Development Environment (SDE) Professional Edition or above, synchronization between class diagram and ERD is supported. This feature facilitates generation of mapped classes from ERD (or vice versa), so you don’t need to manually draw both diagram - just draw one of them and synchronize to another one by simple click!

Please find more details about synchronization between class diagram and ERD feature from:
http://www.visual-paradigm.com/product/vpuml/provides/dbmodeling.jsp#syncorm

By the way, the VP-UML/SDE Professional Edition also supports Object-Relational Mapping (ORM) features so you can generate/reverse database and generate ORM Persistent layer source code.

We provide 30-days free evaluation period for users to experience the features. Please feel free to download our software and request evaluation key from the following link. Enjoy!

All I can say is take a look at the relationships depicted in the ER diagram and with that knowledge, construct a class diagram. If there is any difficulty with that process, ask specifically what is confusing you.
