Ultimate Debian Database (UDD) for short is an ongoing effort to create a relational database to encode information about Debian items (packages, bugs, popularity, ...). Ultimate Debian Database (UDD) gathers a lot of data about various aspects of Debian in the same SQL database. It allows users to easily access and combine all these data.

It is currently being worked on as [wiki:SummerOfCode2008/UltimateDebianDatabase Google Summer of Code 2008 project]. The data currently being imported include:
 * Packages and Sources files, from Debian and Ubuntu
 * Bugs from the Debian BTS
 * Popularity contest
 * History of uploads
 * History of migrations to testing
 * Lintian
 * Orphaned packages
 * Carnivore
 * Debtags
 * Ubuntu bugs (from Launchpad)

  • Popularity contest
  • History of uploads
  • History of migrations to testing
  • Lintian
  • Orphaned packages
  • Carnivore
  • Debtags
  • Ubuntu bugs (from Launchpad)

More data sources can easily be added (and will be in the near future).

  • To connect to udd.debian.org:

    • From merkel.debian.org: /usr/lib/postgresql/8.3/bin/psql 'service=udd'

      • Remark: Please note that some commands like for instance \d might not work because of accessing a PostgreSQL 8.4 server using a PostgreSQL 8.3 client. (see posting on Debian-QA mailing list)

    • From alioth.debian.org: psql 'service=udd'

    • Same with python-psycopg2: conn = psycopg2.connect(host="localhost",port=5441,user="guest",database="udd")

  • Examples of queries: http://udd.debian.org
