Microsoft SQL Server Version Comparison
Microsoft SQL Server may be used as the database engine for the RavTrack PC AVL system.
A free version is available from Microsoft, called “Express”. For small AVL systems where the number of tracked vehicles is small (< 25) and the update rate is fairly slow (< 30 seconds), then the EXPRESS version is probably a good choice. But, for systems requiring higher performance, Microsoft provides a number of high-performance options.
The following table describes the primary differences between the various SQL implementations.
