List of Linux Databases and Database Related Links

Free Open Source as well as industrial strength Oracle, DB2, Informix and Sybase commercially supported databases are available for Linux. This has thrust Linux into the large enterprise data centers.

Commercial Databases


  • Oracle: Oracle currently makes their database server software products and support fully available on Linux. The latest trend is to support blade computing on Linux. Oracle supports a procedural extension to SQL called PL/SQL which adds capability and advantages when used with triggers and database scripts. Oracle also has a full suite of development tools as well as remote access administration tools. (Free trial download)
  • IBM DB2 universal database for Linux: This is IBM's flagship database used in large enterprise data centers. (Free trial download)
  • IBM/Informix - Informix introduced many of the latest database technologies and was considered the most advanced. They were also a case study in poor marketing and were eventually purchased by IBM to save themselves from going under. It may also save IBM from falling too far behind. Informix for Linux is now available from IBM.
  • Borland Interbase - FireBird (now open source and called FireBird)
  • Empress: Embedded Database
  • Adabas (from Germany)
  • MIMER SQL DBMS - ISO PSM standard used for stored procedures.

  • Pervasive - SQL 2000 server database and and SDK. Supports JDBC, ODBC
  • MySQL: (commercial extensions to the open source MySQL database)
    • DBshards - distributed query, sharding and scaling for MySQL. Includes drivers for Java, PHP, Python, Ruby.
  • Raima for Linux - distributed database with mirroring, replication, partitioning. SQL, low level C/C++ and Labview APIs.
  • Sybase for Linux

Analytic DB:

Analytic stores are databases (usually SQL) for large datasets used for reporting and analytics where columnar optimization and compression are important.
  • HP Vertica - column oriented analytic database for fast queries against a large data wharehouse. Nothing shared architecture for scalability. Runs on a distributed grid of servers.
  • Teradata Aster: SQL/map reduce big data analytic database. Structured and unstructured data.
