Hi, David.

>I was really hoping for something really lightweight, with nothing additional to install. My preference is really MS Access. I don't want to install anything additional, if I can get away with it, and I don't want to license anything. I really just want to know what is the best way to store my data, given my needs, that I already have. The utility that this program will provide its users is enough that they really won't care if it runs efficiently or quickly.

Honestly, since I only expect to have 2 or 3 tables in it, with only 1000 or so records in each, maybe I should consider just using XML and loading that in and out of a dataset and doing all queries on the DataSet's DataTables.

Well, if it is not a database application and you just need to have some mostly static data and configuration, XML could be the closest thing you have. Access or Jet is not necesarilly there, but providing the customers have the .NET framework installed, you can do whatever you need with XML, of even Text files. In any case, for short data volumes, XML would provide much more flexible manipulation.

Best luck,
