On some projects a relational model diagram is needed. This refers to database tables and fields and relations. Now I am doing it with class diagram, but it has some differences. For instance, I cannot link a table to a relation. Sometimes you got a M to N relation and an a table do describe de relation. In the grahp is shows like this:

      0..M            0..M
Human -------------------- Place
                |
             Relation

Relation could be: "lives in", "works in", "was born in"

This cannot be said in class diagram and you got tu use tricks:

      1..M    1          1      1..M
Human --------- Relation ----------- Place
