I was busy with new technology & training with intensive course such as SAP HANA and & IBM. Yea, you can say it’s new turning point for my career, and now still learning, i almost achieved what i want to be SAP Hana DBA 🙂 My next goal is cert., yea life goes on, never satisfied.
I will end with great saying: “If the son of Adam had money equal to a valley, then he will wish for another similar to it, for nothing can satisfy the eye of Adam’s son except dust”
Master Data Services
Microsoft SQL Server 2008 R2 Master Data Services (MDS) is another new technology in the SQL Server family and is based on software from Microsoft’s acquisition of Stratature in 2007. Just as SQL Server Reporting Services (SSRS) is an extensible reporting platform that ships with ready-to-use applications for end users and administrators, MDS is both an extensible master data management platform and an application for developing, managing, and deploying master data models.
What i call in short MDS is included with the Datacente, Enterprise, and Developer editions of SQL Server 2008 R2.
Master Data Management – MDM
In the simplest sense, master data refers to nontransactional reference data. Put another way, master data represents the business entities—people, places, or things—that participate in a transaction. In a data mart or data warehouse, master data becomes dimensions. Master data management is the set of policies and procedures that you use to create and maintain master data in an effort to overcome the many challenges associated with managing master data. Because it’s unlikely that a single set of policies
and procedures would apply to all master data in your organization, MDS provides the flexibility you need to accommodate a wide range of business requirements related to master data management.
Master Data Challenges – MDC
As an organization grows, the number of line-of-business applications tends to increase.Furthermore, data from these systems flows into reporting and analytical solutions. Often, the net result of this proliferation of data is duplication of data related to key business entities, even though each system might maintain only a subset of all possible data for any particular entity type. For example, customer data might appear in a sales application, a customer relationship management application, an accounting applikation, and a corporate data warehouse. However, there might be fields maintained in one application that are never used in the other applications, not to mention information about
customers that might be kept in spreadsheets independent of any application.
Older data might be archived and no longer available in operational systems. Other data might reside only in e-mail or in a Microsoft Access database on a computer sitting under someone’s desk. Some organizations try their best not to add another system dedicated to master data management to minimize the number of systems they must maintain. However, ultimately they find that neither existing applications nor ETL processes can be sufficiently extended to accommodate their requirements. Proper master data management requires a wide range of functionality that is difficult, if not impossible, to replicate through minor adaptations to an organization’s technical infrastructure. Last, the challenges associated with analytic master data stem from the need to manage dimensions more effectively. For example, analysts might require certain attributes in a business intelligence (BI) solution, but these attributes might have no source in the line-ofbusiness applications on which the BI solution is built.
Key Features of Master Data Services – MDS
This is best part, the goal of MDS is to address the challenges of both operational and analytical master data management by providing a master data hub to centrally organize, maintain, and manage your master data. This master data hub supports these capabilities with a scalable and extensible infrastructure built on SQL Server and the Windows Communication Foundation (WCF) APIs. By centralizing the master data in an external system, you can more easily align all business applications to this single authoritative source. You can adapt your business processes to use the master data hub as a System of Entry that can then update downstream systems. Another option is to use it as a system of record to integrate data from multiple source systems into a consolidated view, which you can then manage more efficiently from a central location.
Either way, this centralization of master data helps you improve and maintain data quality. Because the master data hub is not specific to any domain, you can organize your master data as you see fit, rather than force your data to conform to a predefined format. You can easily add new subject areas as necessary or make changes to your existing master data to meet unique requirements as they arise. The master data hub is completely metadata driven, so you have the flexibility you need to organize your master data. MDS allows you to manage master data pro aktively. Instead of discovering data problems in failed ETL processes or inaccurate reports, you can engage business users as data stewards. As data stewards, they have access to Master Data Manager, a Web application that gives them ownership of the processes that identify and react to data quality issues.
MDS allows administrators to create versions of the master data. As long as a version has an Open status, anyone with access to the model can make changes to it. Then you can lock the version for validation and correction, and commit the version when the model is ready use. If requirements change later, you copy a committed version and start the process a new. Because MDS is a platform, not simply an application, you can use the API to integrate your existing applications with MDS and automate the import or export processes. Anything that you can do by using Master Data Manager can be built into your own custom applikation because the MDS API supports all operations.
MDS is included on the SQL Server installation media, you perform the MDS installation separately from the SQL Server installation by using a wizard interface. The wizard installs Master Data Services Configuration Manager, installs the files necessary to run the Master Data Services Web service, and registers assemblies. After installation, you use the Master Data Services Configuration Manager to create and configure a Master Data Services database in a SQL Server instance that you specify, create the Master Data Services Webb applikation, and enable the Web service.
Last not but least Master Data Services Database. The MDS database is the central repository for all information necessary to support the Master Data Manager application and the MDS Web service. This database stores application settings, metadata tables, and all versions of the master data. In addition, it contains tables that MDS uses to stage data from source systems and subscription views for downstream systems that consume master data.
