The ooSQLite package embedds the SQLite database engine within the package. Embedding indicates that the SQLite software code is compiled directly into the ooSQLite library. This in turn means that ooSQLite does not need any external piece to work. There is no need for a SQLite library to be installed on the system. There is no reason why a SQLite library can not be installed on the system, but if there is one, ooSQLite will not access it.
