Editing MaxDB (section)

== 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].
