To respond toyour question, what packae to use, depends on your
respnse to the following questions:
- Are you or will you be the owner and the administrator of this database or will others have access?
- How will you keep track of one person visiting multple people? Will they have to sign in and sign out when visiting friends?
However, I am a Fan of relational databases, but I also like Oracle's Datawarehouse, because Oracle has combined relational and object for a great product.
What dtabase software to which you have access?
