I use ThinkDB by Thinking Bytes  http://www.thinkingbytes.com/  ;
It's a great DB and it has a desktop companion for Windows.
Version 2.5 allows up to 80 fields per DB.
Supports 21 field types, including text, numeric and multiple joins.
I don't think there are any limits as to the number of DB's you can store. I have a lot of them. Which is good because There are tons of DB's that people have made and posted on Thinkingbytes web site free to download.
It's only about $40.00

I only list all of this info because this next link doesn't mention ThinkDB. It must be an oversight.  This next link does a comparison of a few DB's. Some of them cost a little less, but you get what you pay for.

You can also go to places like  http://www.pdacity.com/  and look-up what your looking for. If you don't find it there try "What's Related" and find other site that may have Palm Stuff. Also  http://www.google.com

Hope this helps

After looking closer at the comparison page I mentioned, I noticed that it's a couple of years old.  I started looking for the Database called "DB". It's Open Source and can be found at SourceForge.  http://pilot-db.sourceforge.net/  ;
It's up to version 1.0.2 and it looks pretty good so far. It now supports many different data types. Max fields in a new DB is 32. Which in a DB in a Palm is probably a lot.
Think about entering data into 32 fields by hand on a Palm. And that's just for one record, imagine if you have multiple records to fill.

It's still not as good as ThinkDB. But being Open Source it's bound to catch-up quick.
