In May 2003, SAP concluded a cooperation agreement with MySQL AB. As part of this agreement, the SAP DB database will be delivered under the name MySQL MaxDB from database version 7.5.
MaxDB 7.5 is the result of the continuing development of the SAP DB source code. As specified in the releases for SAP applications, you can use the MaxDB 7.5 software as a direct update for the previous SAP DB versions from 7.2.04.
This cooperation agreement does not change anything for SAP customers. Open source users can find information about the new licensing conditions at http://www.sapdb.org/7.4/sapdb_mysql.htm#license.
