Master data is not transaction data but is almost always involved with transactional data. For example: Consider a single transaction "John Doe sold one laser printer, product number MX0315, from Scanners & Printers product family for $90 on 12th December 2011". Master data elements in this transaction are Salesperson (John Doe), Product Group (Scanners & Printers), Product (Laser Printer) and Product Number (MX0315). It can be observed that Master data is synonymous to Dimensions in a data warehouse. What data should constitute master data?What are the different types of data available in an organization?1 2 Unstructured – Data that cannot be organized into identifiable structure. E.g. emails, web pages, word processor documents etc. Transactional – Data that forms the transactions processed by the operational systems of the enterprise, e.g. sales, trades, etc. Transactional data typically describes the activities or transactions of the business. Transactional data typically captures the verbs, such as sale, delivery, purchase, email, and revocation. Metadata – Data that describes the data held in the enterprise information architecture, e.g. definitions of tables and columns in the system catalog of a database, or entities and attributes in a data model. Hierarchical – Stores the relationships between data such as organizational hierarchy, product lines etc. Master – Master data are the critical nouns of a business and fall generally 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. MDM is a set of tools, technology and processes required to create and maintain master data. MDM ensures that an organization's critical information (customers, vendors, products, employees, locations) is uniquely identified, accurately defined and consistently applied across that organization's operational systems – spanning geographic, line-of-business, and application silo boundaries. What is Master Data Management (MDM)?3

What are the key characteristics of MDM system?4 What is MDM hub?5 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. Metadata Management – MDM system should have the ability to manage business & process metadata. Data Repository – MDM system should have the ability to model entities, attributes, complex hierarchies and relationships among the entities. Data Integration – MDM system should integrate with both source and subscribing systems, ideally in both batch and real-time modes. It should support system of entry and system of record operations. Data Quality – MDM system should have high data quality processes supporting standardization, de-duplication, match and merge etc. Fig 1: MDM Hub Source: Microsoft MDM hub contains tools and functions required to maintain master data.

Gartner has identified four different implementation styles for MDM based on criteria like authoring sour ce, data persistence or storage, data latency etc. This is depicted below: What are the different architecture styles of MDM hub systems?6 Repository Model Master data for an enterprise is stored in a single database. The repository data model must include all the attributes required by all the applications 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. Registry Model Registry model is opposite of repository model. Master data is maintained in the application databases, and the MDM hub contains lists of keys that can be used to find all the related records for a particular master-data item. None of the master-data records is stored in the MDM hub. For example, if there are records for a particular customer in the CRM, Order Entry, and Customer Ser- vice databases, the MDM hub would contain a mapping of the keys for these three records to a common key. Hybrid Model As the name implies, the hybrid model includes features of both the repository and registry models. The hybrid model leaves the master-data records in the application databases and maintains keys in the MDM hub, as the registry model does. But it also replicates the most important attributes for each Source: Gartner Consolidation Registry Centralized Coexistence Author Persistence Validation Master Data authored in Operational Systems Author in distributed systems Hub Stores index of master data Hub is System of Reference Operational and Analytical Hub stores a copy apart from author Hub is System of Refrence Downstream Analytics and Reporting Author in Hub Hub persists master data, copies exist in edges Hub is System of Record Author anywhere Persist anywhere System of Refer- ence / Record Upstream Operations Batch to real time Batch to event driven Real time Publish / Subscribe, event-driven Upstream Operations Data Latency Consumer of Master Data

Characteristics Datawarehouse MDM Provide analytical capabilities to analyze data across dimen- sions. Create and maintain a single, consistent version of reference data only. Goal Data Datawarehouse contains transactional (Facts) and Dimen- sional data including any associated hierar- chies. MDM contains only refer- ence data along with any associated hierarchies or relationships, typically corresponding to dimen- sions in a data warehouse. End user presentation / Touch points with business users Data Write back Reports and / or dashboards are primarily used to present data to end users. The touch points with business users revolve around data governance. Emphasis is on maintaining data quality, governance and compliance. Data write back to source system is not supported A master data system can write back data / provide golden copy of data to source system to ensure consistency. Although by definition both look similar and complement each other, they are not. Fundamental difference between data warehouse and MDM are: What is the difference between data warehouse and MDM?8

This could be a challenge when trying to implement a centralized process for data governance if the MDM hub is used to author master data as data synchronization issues could arise. How can data warehouse systems leverage MDM?9 Managing Dimensional table becomes easier if dimensions in a datawarehouse are modeled based on master data. Due to its design, master data consists of business entities which are nothing but dimensions in datawarehouse parlance. ETL work to load dimension data will be greatly reduced if they are drawn from master data. Also, data enters MDM system only if all business rules were fulfilled. This ensures that dimension data is of high quality in data warehouse. Most of the well-established technology vendors are providing MDM solutions as part of their product and solution offerings. Some of the notable ones that figure in the Gartner Magic Quadrant are given below: IBM – IBM has three products for MDM – Infosphere MDM Server, Infosphere MDM Server for Product Information Management and Initiate Master Data Service. IBM has announced a convergence roadmap to integrate the prod- ucts in a phased manner, starting with Infosphere Master Data Management v10.0. Informatica – Informatica acquired the former Siperian Hub and has made it available in its portfolio as the platform for multi domain MDM. Do leading Vendors support MDM?11 Some of the challenges in implementing MDM are given below: What are the challenges in implementing MDM?10 • As an MDM program requires changes to existing / setting up of new data governance processes, there would be a challenge in gaining acceptance and support for the program, unless backed by a strong Business Change program. • An MDM program is not limited to its implementation as a one-time activity. It requires to be run as a continuous program to ensure that the data governance processes remain relevant and efficient with the passage of time and that the master data is consistently used by existing applications and new applications. This requires a contin- uous commitment from management.

Can MDM be implemented with Open Source?12 Not many Open Source vendors exist in the MDM space. Talend, a global company operating in the open source data integration space, has introduced an open source MDM as part of its portfolio. The product comes in 2 editions – a community edition that is available at no charge and a licensed Enterprise edition.
