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. It implemented as a single lightweight library implementing the full SQL engine standard SQL implementation: almost complete SQL-92. There is 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.
