SQLite is a public domain RDBMS database engine that you can find at
http://www.hwaci.com/sw/sqlite/.

Rather than ask you to install SQLite first, because SQLite is public
domain, DBD::SQLite2 includes the entire thing in the distribution. So in
order to get a fast transaction capable RDBMS working for your perl project
you simply have to install this module, and *nothing* else.

SQLite supports the following features:

* Implements a large subset of SQL92

See http://www.hwaci.com/sw/sqlite/lang.html for details.

* 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

Yes, DBD::SQLite2 is small and light, but it supports full transactions!

* Extensible

User-defined aggregate or regular functions can be registered with the
SQL parser.

There's lots more to it, so please refer to the docs on the SQLite web
page, listed above, for SQL details. Also refer to the DBI manpage for
details on how to use DBI itself.
