MaxDB is an and Terabytes of data in 24x7 operation. MaxDB is targeted for large MySAP Business Suite environments and other applications that require maximum enterprise-level database functionality. HISTORY The database development started in 1977 as a research project at the Technical University Of Berlin . In the early 1980s it became a database product that subsequently was owned by Nixdorf Computer , Siemens-Nixdorf , Software AG and today by SAP AG . Along this line it has been named VDN, Reflex, Supra 2, DDB/4, Entire SQL-DB-Server and ADABAS . In 1997 SAP took over the software from Software AG and renamed it to SAP DB. Since October 2000 SAP DB sources additionally were released as open source under the GNU General Public License. In 2003 SAP AG and MySQL AB joined a partnership and re-branded the database system to MaxDB. In 2003, SAP and MySQL concluded a partnership and development cooperation agreement. As a result, SAP's database system SAP DB has been delivered under the name of MaxDB by MySQL since the release of version 7.5 in November 2003. Version 7.5 of MaxDB is a direct advancement of the SAP DB 7.4 code base. Therefore, the MaxDB software version 7.5 can be used as a direct upgrade of previous SAP DB versions starting 7.2.04 and higher. The former SAP DB development team at SAP AG is responsible, now as before, for developing and supporting MaxDB. MySQL AB cooperates closely with the MaxDB team at SAP around delivering improvements to the MaxDB product. Both SAP AG and MySQL AB handle the sale and distribution of MaxDB. The advancement of MaxDB and the MySQL Server leverages synergies that benefit both product lines. MaxDB is subjected to SAP AG's complete quality assurance process before it is shipped with SAP solutions or provided as a download from the MySQL site. FEATURES MaxDB is delivered with a complete set of administration and development tools. Most tools are GUI based and have CLI ( Command Line Interface ) based counterparts. MaxDB offers Bindings for JDBC ; ODBC ; SQLDBC (native C/C++ interface); Precompiler; PHP ; Perl ; Python ; WebDAV ; OLE DB , ADO , DAO , RDO and .NET via ODBC ; Delphi and TCL via Third Party Programming Interfaces. MaxDB is Cross-platform , offering releases for HP-UX , IBM AIX , Linux , Microsoft Windows 2000 , Microsoft Windows Server 2003 , and Microsoft Windows XP . SAP users should check the details of the platform availability on the SAP product pages for the product that will be used together with MaxDB. Distinguishing features MaxDB offers built-in hot backup, does not need any online reorganizations and claims to be SQL 92 Entry-Level compatible. One current development goal is "zero administration" and by this "low TCO". Over the last years MaxDB has been extensively improved, especially for mySAP Business Suite environments. It is fair to expect good Online Transaction Processing (OLTP) performance combined with relatively low hardware requirements, but performance benchmarking is always a must do to know if this (as well as any other) software is able to handle your needs. As each case has its own peculiarities, no promises can hold to every system. High availability mode and small fault record is another historically observed feature of MaxDB, which holds some appraisal from the open source software and db communities. FUTURE RELEASES The next release will have the name MaxDB 7.7.00. Recent presentations on the product contain hints what can be expected for the next major release and/or is considered as a possible future feature. One possible future feature for 7.7.00 the use of Multiversion Concurrency Control (MVCC) instead of the current lock based implementation. SUPPORT MySQL AB and SAP both offer commercial support.
