Master data is the core data of an enterprise that exists independently of specific business transactions and is referenced in business transactions. It builds the foundation for the smooth execution of business processes and well-informed business decisions. Master data represents business objects rather than business transactions and is rarely changed over a long period of time. The following objects are among a company's most important master data objects:

1. Product
2. Customer
3. Supplier
4. Employee


Companies have to be aware that there are several different views on master data. So within one company, the different areas create individual versions of a master data record and the trading partners along the value chain also introduce additional versions.

Master data management (MDM) is a technology that includes the definition of processes and responsibilities for master data maintenance. In case of distributed systems, MDM has to support the synchronization of master data across the enterprise. In addition, MDM has to ensure the availability of master data in good quality. MDM is the sum of all activities, processes and technical mechanisms that are required to achieve these goals.

However, MDM is not only a technology, it also requires joint efforts from different business areas as well as organizational rules and processes. So MDM is an enterprise-wide task that requires the cooperation of a company's business units which includes policies and responsibilities for managing master data.

IT landscapes today are quickly moving towards dynamic environments enabled by service-oriented architectures (SOA) where specific master data strategies play an important role. Business processes work successfully within the context of dynamic services only if they are founded on reliable information - that is, consistent master data. Why? Because processes cannot successfully exceed application boundaries if they do not know how key master data should be translated and interpreted in these systems. Prior to shifting to a service-oriented architecture, companies must cleanse their data across system boundaries; otherwise business processes will get stuck on these issues.

SAP NetWeaver MDM fits the above-mentioned description of an MDM solution. It ensures that questions about master data as specified below are answered so that business processes can run smoothly and business decisions are well informed:

SAP NetWeaver MDM offers the capabilities and functions to handle master data according to a company's needs. These capabilities and functions can be used in the following ways:

SAP NetWeaver MDM is used to aggregate master data from across the entire system landscape (including SAP and non-SAP systems) into a centralized repository of consolidated information. In this context, MDM also acts as a central hub and allows the enrichment of data via third-party integration. The consolidated master data is a prerequisite for sound business operations and reliable company-wide reporting.

High information quality is ensured by syndicating harmonized master data that is globally relevant to the subscribed applications. In these remote applications, master data can be enriched with locally relevant information

A company's quality standards are supported by ensuring the central control of master data, including maintenance and storage. Centrally created master data can be syndicated to remote systems as required using distribution mechanisms.

In addition to the above mentioned ways, there are many other ways to use SAP NetWeaver MDM. The specific usage depends on the main focus of the task that has to be fulfilled.

MDM can be divided into various key capabilities and offers a comprehensive set of tools and functions for all these key capabilities.

Import and export mechanisms, services and predefined content ensure that master data can be integrated from a wide range of sources. All these functions are described in the master data integration section.

Master data operations comprises all functions and tools that are required in operational business after data has been migrated. This includes role-based access to the data, for example, or powerful and efficient search capabilities.

To be able to perform business processes efficiently and without errors, high quality data is essential. In the key area of master data quality, MDM offers functions and tools to guarantee high standards of master data quality in your company.
