Working with data tables

I have some questions about Data Tables. I have read the Help and the Tutorials and I can’t find the information that I need(or I can't understand it). This is the first time that I use AggreGate and there are a few things that aren’t clear for me. There are AggreGate Client, Server and Agent. As I understand Common Tables and Database can be make only on AggreGate Server and the tables can be visualized in AggreGate Client with DataTable Editor. Am I right?
