I have been doing databasing this semester at Uni and apart from all the theory and learning SQL etc, I have spent a fair bit of time rummaging around images such as the one to the left to try and come up with database designs.
It takes a little time to get used to doing this and one has to develop one's own method and part of that for me is rummaging around in amongst other ER diagrams that solve a similar scenario. In reality there are only so many possibilities I think, and I have heard there are 7 (correct me if I am wrong) so it is not such a crazy idea. Personally I think the processes and language used throughout a course such as the one I am doing goes a long way to confusing the design process!
I have found a great resource Database Answers created by Barry Williams in London which has around 450 database models which can be used as a starting point for any database project.
