SAP NetWeaver Master Data Management

SAP NetWeaver Master Data Management (SAP NW MDM) is a component of SAP's NetWeaver product group and is used as a platform to consolidate, cleanse and synchronise a single version of the truth for master data within a heterogeneous application landscape. It has the ability to distribute internally and externally to SAP and non-SAP applications. SAP MDM is a key enabler of SAP Service-Oriented Architecture. Standard system architecture would consist of a single central MDM server connected to client systems through SAP Exchange Infrastructure using XML documents, although connectivity without SAP XI can also be achieved. There are five standard implementation scenarios: 
Some features (for example, workflow) require custom development out of the box to provide screens for end users to use.
History.
SAP is currently on its second iteration of MDM software. Facing limited adoption of its initial release, SAP changed direction and in 2004 purchased a small vendor in the PIM space called A2i. This code has become the basis for the currently shipping SAP MDM 5.5, and as such, most analysts consider SAP MDM to be more of a PIM than a general MDM product at this time.
SAP NetWeaver MDM 7.1 was released in ramp-up shipment in November 2008 and unrestricted shipment in May 2009. This new version has an enhanced MDM technology foundation to build pre-packaged business scenarios and integration. 
Recognition.
Two of the top three finalists of the Gartner MDM Excellence Awards 2009 were SAP NetWeaver MDM customers: Kraft Foods and BP ranked 1st and 2nd by a team of Gartner analysts, based on their successful implementations of very complex MDM projects.
