Generate Class Diagram from Entity Relationship Diagram (ERD)
October 30, 2009
Visual Paradigm supports generating class diagrams from ER diagrams (entity relationship diagram). Entities and relationships are mapped with classes and associations accordingly. This tutorial teaches generating class diagrams from entity relationships diagrams and how to synchronize description between classes and entities.
Thank you for this much of information this is very helpful for me.
thank you once again.....
I cant finde this sync on my workspace.
I'm using VP 7.0
1. Which Edition you are using?
2. Sync to different diagram selection available from 7.1 or later.
I'm trying the community edition and thinking to buy a different version betwen modeler and standard. what's the lower release with this feature and the creation of SQL (for mySql) from ER Diagram?
thanks for information.
The Professional Edition is the minimum edition that supports this feature and other ORM features like database/orm code generation, and the reversal of database.
If you are looking for database and class engineering, you may consider another product of us, called DB Visual ARCHITECT. The Professional Edition of DB Visual ARCHITECT supports class and entity relationship modeling, and database engineering, and is a more cost effective solution comparing to VP-UML, provided that you only need class and database modeling and engineering features.
For details about DB Visual ARCHITECT, please read:
is it possible to create the ERD from a class diagram or is it only from possible to create the class Diagram from the ERD?
is this feature available on evaluation copy for enterprise edition?
The tool menu doesn't show the "ORM" option sub menu.
I'm ussing version 10.1 build 20130203
in windows xp sp3 with java jre 1.6.35
Thanks in advance.
VP-UML has undergone many changes since the time this tutorial was written. Therefore, the instruction is a bit outdated. We are sorry about this.
To access the ORM features, please go through this menu: "Tools > Hibernate" instead.
hi I tried to create the ERD from a class diagram but I couldn't do and I got the message "you have no write permission on C://Program Files|Visual Paradigm 11.1"
the reason why I can't do is trial version?
The trial should not have this problem. Can you contact our support team by firstname.lastname@example.org to check your issue?
i can make class-diagram from erd but i can't create erd from class-diagram. if i click " Synchronize Class Documentation to ERD", nothing is happening. how can i contact your support team? am i email to "email@example.com"?
You should put this last issue public because I have the same problem. Can't synchronize ORM persistable classes ant association to ERD. Nothing happens.
Could you send us your project for reproduce the problem and for diagnosis? Please send by submitting a ticket at:
its not changing class diagram to er diagram when I use synchronize option
I guess your classes are not >. If this is not the problem, could you submit a ticket to our team to let us check with you in further? You can submit at:
i want to generate simple c# classes with properties and functions without orm mapping classes. How can i achieve this?
thanks in advance
how can i generate .java from>?I got a warning:(There is no class model available for code generation (16 classes are ignored)."
how can i generate .java from orm persistable?I got a warning:(There is no class model available for code generation (16 classes are ignored)."
I guess your classes are not <<ORM Persistable>>. If this is not the problem, could you submit a ticket to our team to let us check with you in further? You can submit at:
