A Metamodel for Master Data
نویسندگان
چکیده
The term ‘Master Data’ brings up different interpretations and connotations, especially with vendors espousing the “single version of the truth”. Is there a single version of the truth? Practical realities suggest that we need to continue to live with existing versions – at least until the “single version” is reached. So how do we handle the co-existence of “multiple versions” of the truth? This paper examines a metamodel that defines what master data is, the types of master data, and criteria for determining master data. The metamodel visits master data administration, privileges and master data services including change management, metadata migration and data migration for master data is also reviewed. The impact of changes to an enterprise going the master data route, along with the emphasis to influence future management direction is also examined. Several administration aspects make use of established ISO standards in metadata IS:11179-3 and IS:19763.

متن کاملAn Improved N-dimensional NURBs-based Metamodel
Non Uniform Rational B-splines (NURBs) are proved to be very promising for metamodeling in engineering problems, because they have unique properties such as local modification scheme, strong convex hull property, and infinitely differentiability, etc. Since NURBs are defined by control points, knot vector, and weights associated with control points, the precision of NURBs is influenced by all o...

“The Times They Are A-Changing” (B. Dylan), and with them the structures, schemas, master data, etc. of data warehouses. For the correct treatment of such changes in OLAP queries the orthogonality assumption of star schemas has to be abandoned. We propose the COMET model which allows to represent not only changes of transaction data, as usual in data warehouses, but also of schema, and structur...

متن کاملFlattening the Metamodel for Object Databases
A metamodel definition presents some important issues in the construction of an object database management system, whose rich data model inevitably increases the metamodel complexity. The required features of an object database metamodel are investigated. Roles of a metamodel in an objectoriented database management system are presented and compared to the proposal defined in the ODMG standard ...
