Sql Lite

"SQLite is an ACID-compliant relational database management system contained in a relatively small C library. It is a public domain project created by D. Richard Hipp.

Unlike the usual client-server paradigm, the SQLite engine is not a standalone process with which the program communicates, but is linked in and thus becomes an integral part of the program. Therefore the primary communication protocol are direct API calls within the programming language. This can have a positive impact on the amount of overhead, latency times and overall simplicity. The entire database (definitions, tables, indices, and the data itself) is stored as a single standard file on the host machine. Its simple design is achieved by locking the entire database file at beginning of a transaction."
