SQLitening is a client/server implementation of the very popular SQLite database.
SQLitening is a programmer's library in standard Win32 DLL form. It is installed as a standard Windows Service. In addition to client/server mode, the library allows the programmer to also access SQLite databases in local mode. In either mode (local or client/server), the database is extremely fast and robust.
Installation is a breeze - you simply copy a couple of DLL's to the folder where your application resides. If you work in client/server mode, you create a folder on your server and start the SQLitening Windows Service from the Administration program. You may need to modify the standard configuration text file to set permissions and port numbers/host names. Simple.
The current version is 1.30, the release of version1.40 is planned for July 12, 2010.
