Master data mapping scheme permitting querying

Abstract

Embodiments permit searching across different system landscapes, for data associated with master data objects. A map is constructed comprising (explicit, inferred) connections between different pieces of data located in various databases, systems, and landscapes. In certain embodiments the map is constructed utilizing a parameter (e.g., family name) present in a received query, as a boundary condition. The map may be in tabular form, and may conform to a particular notation scheme. Once the map is constructed, the query is executed thereupon to search for relevant data. The corresponding query result is received and stored, ultimately for communication back to the user posing the original query. Embodiments may be particularly suited to returning private data of a unique entity (e.g., natural person, corporation, juristical person) that is stored over a variety of different master data objects (e.g., employee, customer, supplier) and across complex system landscapes.
