Dbd::sqlite is a perl dbi driver with a self-contained relational database management system. it embeds a small and fast embedded sql database engine called sqlite (see sqlite3) into a dbi driver. it is useful if you want a relational database for your project, but don't want to install a large rdbms system like mysql or postgresql.

sqlite supports the following features:

* implements a large subset of sql92 ()
* a complete db in a single disk file
everything for your database is stored in a single disk file, making it
easier to move things around than with dbd::csv.
* atomic commit and rollback
the engine is very fast, but for updates/inserts/dml it does perform a global lock on the entire database. this, obviously, might not be good for multiple user systems. the database also appears to be significantly faster if your transactions are coarse.
