SQLite is an almost ACID-compliant embedded relational database management system contained in a relatively small (~225 kB) C programming library. The source code for SQLite is in the public domain. The SQLite engine is not a standalone process with which the application program communicates. Instead, the SQLite library is linked in and thus becomes an integral part of the application program. The library can also be called dynamically. The entire database (definitions, tables, indices, and the data itself) is stored as a single cross-platform file on a host machine.
