A first group master data management node may be assigned to centrally manage the first set of master data management nodes, the first group master data management node maintaining master data management functionalities at a group level and providing a single logical view of master data to the first set of master data management nodes. Each master data management node in the first set has data access link with the first group master data management node based on implementation style of said each master data management node.
