db4o

Well I have been experimenting with database's and I have decided to use db4o as the default embedded database for my product. Its easy to use, easy to integrate, and generally does what it says on the tin without complaint.

While investigating possible databases I had a disastrous experience with SQL Server Express where it kept on complaining about sqlncli.msi being corrupted, which I fixed (long story), but I would never want a potential user to go through the same pain I did.

In saying that, I will probably find some way of supporting SQL Server Express, Oracle Express, and DB2 at a later date so that more advanced users can use a database of there choice.
