SQLite

SQLite is a RDBMS present in a C Program library. Unlike other DBMS, SQLite is not a client–server database engine, but is integrated with the end program. It implements most of the SQL standards for which it uses a SQL syntax, which is dynamically and weakly typed, and it doesn’t have the domain integrity.  In contrast to many other database management systems, SQLite is not a client–server database engine. Rather, it is embedded into the end program.
