Question

in a relational database, can we have a table without any relation with the other tables?

Answer 1

I'm creating a company management database and I have a "Company_Expenses" table that I just need for summery reports on the Company's revenues. I can't think of anything this table might need to be connected to so it's just on it's own for now.
