What exactly are you looking for? An example of the graphical representation of a data model? Or SQL code examples for each one of your requirements?

Graphical would be cool but if you can just indicate the foreign keys in the table description that's good. Thx much

Hi All<br />
<br />
&nbsp; I have a situation where there are two tables &nbsp;- Table A (a1 (PK)) and Table B (b1 (PK)) . <br />
I have business requirement to have the following relationships between the two tables. &nbsp;<br />
1) Many to Many relationship from A to A<br />
2) One to Many from B to A<br />
3) One to One from B to B<br />
<br />
&nbsp; &nbsp; &nbsp;Please let me know how can I model the best way.<br />
<br />
&nbsp; &nbsp; Also, I was trying to model the 3 relationships into one table cause the relationships have common attributes like start, end dates and codes. Please let me know if it is possible to model the above 3 relationships in one single table, and how?

A modeling language is any artificial language that can be used to express information or knowledge or systems in a structure that is defined by a consistent set of rules. The rules are used for interpretation of the meaning of components in the structure; modeling languages can be either graphical or textual. The Unified Modeling Language (UML) is a general-purpose, developmental, modeling language in the field of software engineering, that is intended to provide a standard way to visualize the design of a system.
