Where can I learn more about Conceptual Data Model? I have to create a schema based on the convention in the image below.

enter image description here

I don't understand the "bubble" (or relationship) between the two entities. What should be the name of a relationship (verb, nom, etc.)?

Is there books or websites which cover this data modelisation theory? What is the name of those diagram? I googled as much as I can around "Conceptual Data Model" and I didn't find anything similar to the image above.

Thanks for the help.

P.S. I will be using Open ModelSphere "Conceptual Data Model".

Try learning the Entity Relationship Model : http://en.wikipedia.org/wiki/Entity-relationship_model

And also the Unified Modeling Language : http://en.wikipedia.org/wiki/Unified_Modeling_Language

Here is one book by Korth: http://www.db-book.com/ for starting DBMS. Have a look at the ER-Model chapter.

For UML have a look at : http://www.amazon.com/UML-Distilled-Standard-Modeling-Language/dp/020165783X?tag=particculturf-20
