I'm currently working on a project in which we're required to define a Entity Relationship Diagram and a UML Class Diagram from a set system.
I've successfully managed to define the ERD. It required me to break down information from a specification and form them into entities and then define a relationship between the entities to represent the system.
Now that I've done that I'm now onto the UML Class Diagram, but the only issue is I have no idea how to incorporate what I've defined inside my ERD into a UML Class Diagram as I've been told the structure between both diagrams are quite different.
- Do entities from the ERD in a sense serve as a class in the UML?
- Do the attributes from the entities in the ERD form the attributes in the classes?
- How can you easily define what attributes and methods you make public, private, and protected?
I understand a lot of the basics of UML and ERD on their own, but to take an entity relationship diagram and appropriately incorporate it into a UML is something i'm quite lost on where to start with.
Any tips or advice would be greatly appreciated.
