'''MaxDB''' is an [[ANSI]] [[SQL-92]] (entry level) compliant [[relational database management system]] ([[RDBMS]]) from [[SAP AG]], which was also delivered by [[MySQL AB]] from 2003 to 2007. MaxDB is targeted for large SAP environments e.g. [[mySAP Business Suite]], and other applications that require enterprise-level database functionality.

== History ==
The database development started in 1977 as a research project at [[Technische Universität Berlin]] headed by Rudolf Munz. In the early 1980s it became a database product that was subsequently owned by [[Nixdorf Computer AG|Nixdorf Computer]], [[Siemens-Nixdorf]], [[Software AG]] and today by [[SAP AG]]. It has at various times been named VDN, RDS, Reflex, Supra 2, DDB/4, Entire SQL-DB-Server and [[Adabas D]]. In 1997 SAP acquired the software from Software AG and developed it as SAP DB, releasing the source code under the [[GNU General Public License]] in October 2000.

In 2003 SAP AG and MySQL AB jointly re-branded the database system as MaxDB.  In October 2007 this reselling agreement was terminated and sales and support of the database were reverted to SAP.<ref>[http://www.mysql.com/news-and-events/press-release/release_2007_40.html MySQL AB :: MySQL AB to Optimize its Open Source Database for SAP NetWeaver]</ref>  SAP AG now manages MaxDB development, distribution, and support. New versions of the [[source code]] of MaxDB are no longer available under the GNU General Public License.  SAP also stated that "Further commercial support concepts to cover mission critical use requirements outside of SAP scenarios are currently subject to discussion."<ref>[https://archive.today/20121217180122/https://www.sdn.sap.com/irj/sdn/weblogs?blog=/pub/wlg/7514 ''MaxDB back under the SAP roof!'']</ref>

MaxDB since version 7.5 is based on the code base of SAP DB 7.4. Therefore, the MaxDB software version 7.5 can be used as a direct upgrade of previous SAP DB versions starting at 7.2.04 and higher.

SAP has announced that there will be no minor or major updates after version 7.9. SAP is sunsetting the product, favoring the HANA database instead [https://me.sap.com/notes/1722076].
== Features ==
MaxDB is delivered with a set of administration and development tools. Most tools are available with both a [[GUI]] and [[command line interface]] (CLI). It offers [[language binding|bindings]] for [[JDBC]]; [[ODBC]]; [[SQLDBC]] (native C/C++ interface); precompiler; [[PHP]]; [[Perl]]; [[Python (programming language)|Python]]; [[WebDAV]]; [[OLE DB]], [[ActiveX Data Objects|ADO]], [[Data Access Object|DAO]], [[Remote Data Objects|RDO]] and [[.NET Framework|.NET]] via [[ODBC]]; [[Delphi (programming language)|Delphi]] and [[Tcl]] via Third Party Programming Interfaces. MaxDB is [[cross-platform]], offering releases for [[HP-UX]], [[IBM AIX]], [[Linux]], [[Solaris (operating system)|Solaris]], [[Microsoft Windows 2000]], [[Microsoft Windows Server 2003]], and up to [[Microsoft Windows 10]].<ref>{{cite web |url=https://help.sap.com/doc/a790c64697bd4e2da0b1cc51142a62b6/7.9/en-US/GUIDE_WIN__MAX_UPG.pdf |title=Upgrade to SAP MaxDB Database 7.9 on Windows |quote=5.3 Installing or Upgrading Database Studio for SAP MaxDB |accessdate=6 December 2017}}</ref>

MaxDB offers built-in [[Backup#Live data|hot backup]], does not need any online reorganizations and claims to be SQL 92 Entry-Level compatible.

MaxDB since version 7.7.00, uses [[multiversion concurrency control]] (MVCC) instead of the previous lock based implementation.

== Licensing ==
MaxDB was licensed under the [[GNU General Public License]] (GPL) from versions 7.2 through 7.6.  Programming interfaces were licensed under the GPL with exceptions for projects released under other [[open source license]]s.

SAP DB 7.3 and 7.4 were licensed as GPL but with [[LGPL]] drivers. MaxDB 7.5 was offered under dual licensing, i.e. licensed as GPL with GPL drivers or a commercial license.

From version 7.5 through version 7.6 onwards distribution of MaxDB (previously SAP DB) to the open source community was provided by MySQL AB, the same company that develops the open-source software database, [[MySQL]].
Development was done by SAP AG, [[MySQL AB]] and the [[open-source software]] community.

In October 2007 SAP assumed full sales and commercial support for MaxDB. MaxDB 7.6 is now [[closed source]], available free-of-charge (without support, and with usage restrictions) for use with non-SAP applications.
