Hi All,

I would like to get some tips on Application Database design for the internet users. We are developing a customer based application where in each customer has own password. And there is a requirement that we should provide a individual backup for each customer and restore it back when necessary.

Is it a good idea to create a seperate database for each customer with the same number of tables(150) in each database?

How many maximum number of Databases can a DB2 Server hold?

How much RAM does each Database occupy?

Are they any disadvantages with sort of architecture?

Thanks in Advance
