Lynn, all good points. My brother in-law has an app that is actually going through this same process. He wants the customers to own the data, but some want him for some reason to own it.

As I said I won't be getting back to my project for some months now. I have seen both methodologies - One database with a customer number to separate customer and and version where each customer has his/her own database. I am not sure for my project which is preferable. All the issues that were raised will hopefully help me make a decision.

The one thing I have gleaned from my posting is that there is no one clear cut answer.

Thanks
