  3. 3. 1 What are the different types of data available in an organization? 2 What data should constitute master data? Data available in an organization can be classified into five types: Master data are the core elements of the business that are applied to multiple transactions and are used to categorize, aggregate, and evaluate the Unstructured – Data that cannot be organized into identifiable structure. E.g. transaction data. Master data is not transaction data but is almost always emails, web pages, word processor documents etc. involved with transactional data. For example: Consider a single transaction "John Doe sold one laser printer, product number MX0315, from Scanners & Transactional – Data that forms the transactions processed by the operational Printers product family for $90 on 12th December 2011". Master data systems of the enterprise, e.g. sales, trades, etc. Transactional data typically elements in this transaction are Salesperson (John Doe), Product Group describes the activities or transactions of the business. Transactional data (Scanners & Printers), Product (Laser Printer) and Product Number typically captures the verbs, such as sale, delivery, purchase, email, and (MX0315). It can be observed that Master data is synonymous to Dimensions revocation. in a data warehouse. Metadata – Data that describes the data held in the enterprise information What is Master Data Management (MDM)? 3 architecture, e.g. definitions of tables and columns in the system catalog of a database, or entities and attributes in a data model. MDM is a set of tools, technology and processes required to create and maintain master data. MDM ensures that an organizations critical information Hierarchical – Stores the relationships between data such as organizational (customers, vendors, products, employees, locations) is uniquely identified, hierarchy, product lines etc. accurately defined and consistently applied across that organizations operational systems – spanning geographic, line-of-business, and application Master – Master data are the critical nouns of a business and fall generally silo boundaries. into four groupings: people, things, places, and concepts. It should be the single trusted source of data that everyone in an enterprise relies on and uses.www.hexaware.comHexaware Technologies. All rights reserved. 1 2
  4. 4. 4 What are the key characteristics of MDM system? CRM ERP SharePoint HR Finance A MDM system typically enables: Data Governance – It should provide robust security for the underlying models, define data governance policies and procedures, and support workflows to implement data governance policies. Master Data Web Services Metadata Management – MDM system should have the ability to manage Syncronization business & process metadata. MDM Hub Data Repository – MDM system should have the ability to model entities, Data Quality attributes, complex hierarchies and relationships among the entities. Metadata Store Data Integration – MDM system should integrate with both source and Stewards hip and Workflow Governance subscribing systems, ideally in both batch and real-time modes. It should support system of entry and system of record operations. Entity Version Hierarchy Version Control Control Data Quality – MDM system should have high data quality processes supporting standardization, de-duplication, match and merge etc. 5 What is MDM hub? Entity Management Hierarchy Management The MDM hub is a database with the software to manage the master data that is stored in the database and keep it synchronized with the transactional Fig 1: MDM Hub Source: Microsoft and/or analytical systems that use the master data.

The applications that consume, create, or maintain master data are all modified to use the master data in the hub, instead of the master data previously maintained in the application database. For example, the Order Entry and CRM applications would be modified to use the same set of customer tables in the master-data hub, instead of their own data stores.

Some of the challenges in implementing MDM are given below: • As an MDM program requires changes to existing / setting up of new Most of the well-established technology vendors are providing MDM solutions data governance processes, there would be a challenge in gaining as part of their product and solution offerings. Some of the notable ones that acceptance and support for the program, unless backed by a strong figure in the Gartner Magic Quadrant are given below: Business Change program. • An MDM program is not limited to its implementation as a one-time IBM – IBM has three products for MDM – Infosphere MDM Server, Infosphere activity.
