Hi All,
I have been asked to collect some information on ERL (Entity Relationship Link - I think) for a project proposal.
I heard about ERD (Entity Relationship Diagrams) but not on ERL. Can some one help me on this?
Any help is appreciated.
Thanks,
Bala.

Hi,
I have not heard of any term ERL in reference to ER diagrams.
I looked up the net on ERL -and only thing that makes sense is ERL stands for Electronic Reference Library. Does that make sense with respect to your project?
Thanks
Ritu

You can find E-R modelling on database conceptual design. You can find it in database book.

Hi,
My client has mentioned ERL in his project requirement. I am sure, it's not Electronic Reference Library.
I also requested my client to explain. Mean time, If any one come across about ERL, please let me know.
Thanks,
Bala.

Note also that UML class diagrams are not ER diagrams. UML borrows a lot of notation from the data-modelling domain, but they are not equivalent.
