Ultimate Debian Database (UDD)

General information

Ultimate Debian Database (UDD) gathers a lot of data about various aspects of Debian in a single SQL database. It allows users to easily access and combine all this data.

You can have a look at the UDD Schema.

More information about UDD is available at wiki.debian.org/UltimateDebianDatabase.

UDD-based services

Examples

Some example queries are provided as CGI scripts, to make it easy for everyone to run them. You can browse them or view the source code.

Timing information

If you want to know when UDD is being updated, you can check the crontab file. The timestamps table can tell you when a data source was last updated.

Database dump

A full dump of the database, generated every two days, is also available. Be careful, it's quite big (400 MB gzipped, and growing).
