Let’s face it, most of the apps in the galaxy we live in are data bound. I don’t write apps that use sockets and presumably most of you don’t either, correct?

Now, in our day to day lives, we generally use a database of sorts, may it be SQL Server, MySQL, Oracle, PostgreSQL etc. all of which are relational. You have heard the famous cliche, “There are multiple ways to skin a cat”. Well, let’s not go there…suffice it to say, there are many solutions to a problem.

Output from the newly inserted records in the Composite table:
