Databases and Moodle
When talking about Moodle and databases there are actually two different kind of things which can be meant:
- a) The Moodle activity named Database
- b) The database on your server where Moodle stores all its content
a) Database activity
See
- Category:Database activity module
- Database module
- Database module FAQ
- Database module forum
- How do I import and export database entries?
b) Moodle database
See
- Category:DB
- Databases forum

Moodle core libraries
Moodle's core libraries provide lots of functions for working with the database. See /lib/datalib.php for higher level functions and /lib/dmllib.php for lower level functions.

XMLDB stores the database definition in an XML format that can be used to install Moodle on any database.
