Hi,
I have built my own datasource and business classes. My business class will create a instance of relevant datasource object and save it in property.

Now, i would like to built other classes such as collections, and etc which will access table but not much. For example, I have a class that will lookup my table, compile and run the code stored in memo field. It need some function of open table and locate record.

My question is, should I subclass business class for this case? Or, I should built it seperately, and just re-write the code for open table and locate record?

Thank you
