>> By the way, having xxx1, xxx2 in code or data structures is often a warning sign that you might want to consider some kind of container or list structure. >>Also, it as useful to put effort into good naming in data models as it is for variables.

You are soo right, my boss and my teachers used to eat my head about proper naming convention, When i started this project, i re wrote code two times, becausei forgot what the variables meant and what the code section did, now i am putting adequate comments and using Long and descriptive variable names.
Learning this the hardway
