Management of the bench-mark data

The Management of the bench-mark data (in English Reference Dated Management , or Master Data Management , whose initials are MDM ), is a discipline of the Technologies the information which relates to the Bench-mark datum shared by several computing systems or distinct groups. GDR (MDM) is necessary to guarantee coherent programming between various architectures of systems and functions trades.

The large companies often have computing systems which are used by various functions trade (for example Marketing, Research and development, Ventes, Finances, etc) and which extend on multiple countries. These various systems often need to divide Donnée S key which are useful for the parent company (for example produced S, customer S, and suppliers). It is critical for a company to use these data shared in a coherent way through various computing systems.

The management of the bench-mark data takes also a great importance when two companies or more want to divide Donnée S beyond the perimeter of these companies. In this case, the GDR becomes an industrial subject, as it is the case of the industry of finance and the Straight Through Processing) or T+1.

In a traditional model of information system, the management of the bench-mark data is necessary to coordinate various systems ERP between them, and with the decisional systems. In the Y computing model , the Management of the bench-mark data is one of these three types of programming:

transactional computing (typically ERP),
DSS (Decision Support Systems),
and MDM.

These types extend from the operational reporting to the Executive Information System S.

In a model less structured of the engineering type of knowledge, the management of the bench-mark data is also necessary to provide metadata in order to incorporate and to integrate compromise data, contained in computer's resources, often of the resources Web.

In both cases, the management of the bench-mark data is necessary for the projects of Entrepôts of data which are typically integrated in the systems of decisional Ingénierie. Sometimes for this reason, systems MDM provide a virtual layer of metadata.
