This application is really slow, maybe because it was made with RealBasic. Still, Sqlite is capable of much better performances so there might be some other problems in your code, in the framework you use or in your queries. The application also misses some very important features but that's another story.

Sqlite users should have a look at this page http://www.mamasam.com/sqlitecreate/index.html
Unfortunately, this cocoa application has not been released yet... It is planned for June 2004.
