is this possible in Sesame?

thanx

I am trying to translate an application from Q&A into Sesame, however the Q&A application was simply one huge and ugly database, where redundant field names existed.   For example, if a client had multiple insurance policies then there would exist fields such as PolicyNo1, PolicyType1, PolicyAmount1, PolicyNo2, PolicyType2, PolicyAmount2, etc.., which is a poor design. 

It makes sense to me to split this database into several databases: one for Client Info(address, name, etc), one for Policies(number, type, amount, etc), one for Children(name, DOB), etc..  Correct?

But the problem is that I cannot incorporate the various info from the databases together.  Say, I want to create a report where I can display all the children and policies belonging to a particular client.  A client can have several policies and children, so is there any way to combine the three databases, joining them by a client ID?   

Also, I would like to do a mail merge where (for example)I can display all the policies for a client and his birthday and address. How do I export data from multiple tables?

Maybe I'm missing something because there *should* be a method to combine data from several tables allowing me to create reports and whatnot without having one gigantic database and redundant fields?

Thanx a bunch
