Database for Open Source Project [closed]

Question

Which database would you use for an Open Source Project?

I am looking for something that has little or no setup required by the end-user.

Update: Database size will be relatively small (less than 100,000 records). Application will be written in C#.

Answer 1

If you're looking for embedded database (I guess you do if you ask for something easy for end-user), then SQLite is the most widely deployed SQL database in the world.

Depends on what language you're using, you might need appropriate wrapper for SQLite library.

Update: For .NET, the best wrapper for SQLite is System.Data.SQLite.dll from phxsoftware.
