Editing Oracle Database (section)

=== Competition ===

In the market for relational databases, Oracle Database competes against commercial products such as [[IBM Db2]] and [[Microsoft SQL Server]].<ref name="rdbmslateryears20070612">{{Cite interview |interviewer=Burton Grad |title=RDBMS Plenary Session: The Later Years |url=https://archive.computerhistory.org/resources/access/text/2013/05/102701921-05-01-acc.pdf |access-date=2025-05-30 |publisher=Computer History Museum |date=2007-06-12}}</ref> Oracle and IBM tend to battle for the mid-range database market on Unix and Linux platforms, while Microsoft dominates the mid-range database market on [[Microsoft Windows]] platforms. However, since they share many of the same customers, Oracle and IBM tend to support each other's products in many middleware and application categories (for example: [[WebSphere]], [[PeopleSoft]], and [[Siebel Systems]] [[Customer relationship management|CRM]]), and IBM's hardware divisions work closely{{Citation needed|date= February 2010}} with Oracle on performance-optimizing server-technologies (for example, [[Linux on IBM Z]]). Niche commercial competitors include [[Teradata]] (in data warehousing and business intelligence), Software AG's [[ADABAS]], [[Sybase]], and IBM's [[Informix]], among many others.

In the cloud, Oracle Database competes against the database services of AWS, Microsoft Azure, and Google Cloud Platform.

Increasingly, the Oracle database products compete against [[open-source software]] relational and non-relational database systems such as [[PostgreSQL]], [[MongoDB]], [[Couchbase]], [[Neo4j]], [[ArangoDB]] and others. Oracle acquired [[Innobase]], supplier of the [[InnoDB]] codebase to [[MySQL]], in part to compete better against open source alternatives, and acquired [[Sun Microsystems]], owner of MySQL, in 2010.  Database products licensed as open-source are, by the legal terms of the [[Open Source Definition]], free to distribute and free of royalty or other licensing fees.
