Entity Relationship and Use Case

[bodhi]

Hey,

Does anyone know any good websites for learning the basics of Use Case modelling and Entity Relationship modelling.

Thanks.

Bodhi.

Entity Relationship Diagrams you list the entities and then show either a one to one, one to many, or many to many relationship between them... depending which level ERD you want to do, assuming thats the same as a ERM...

I know what entity relationships are, i did them at uni a couple of years ago. I just want to brush up on it a bit and also relearn Use Case. Was just wondering if anyone could recommend any websites which are any good?
