What Tables in fm8?

I am new and trying to determine what tables to create for this
problem.

There is a list of people in Group A. And a different list of people in
Group B.

One person in Group A will me matched with one or more people in Group
B.

Each person in Group A will make a periodic donation to person in Group
B.

What tables do I set up to keep track of who donated to whom and how
much?
