SpatiaLite is an open source library intended to extend the SQLite core to support fully fledged Spatial SQL capabilities.
SQLite is intrinsically simple and lightweight:

• a single lightweight library implementing the full SQL engine
• standard SQL implementation: almost complete SQL-92
• no complex client/server architecture
• a whole database simply corresponds to a single monolithic file (no size limits)
• any DB-file can be safely exchanged across different platforms, because the internal architecture is universally portable
• no installation, no configuration

SpatiaLite is smoothly integrated into SQLite to provide a complete and powerful Spatial DBMS (mostly OGC-SFS compliant).
Using SQLite + SpatiaLite you can effectively deploy an alternative open source Spatial DBMS roughly equivalent to PostgreSQL + PostGIS.
