Thank you for the post, asadkhan. Please note, however, that the "sample database" forum is tightly moderated. Strictly for future reference, normally you would post in some other forum such as General or Database Design and we would ask you for permission to move it. After discussion, we agreed that this could be posted as an example of a simple but functional DB. Please do not directly post to the Sample Database forum again without giving us more time to review and examine your offering.
