Master Data Management (MDM) is often defined as "management of master data (customer, product, supplier, etc.) that is shared across disparate IT systems and groups." However, this simplistic description doesn't do justice to the complexity of the MDM's task and problem area. Master Data Management encompasses areas such as Customer Data Integration (CDI), Product Information Management (PIM), and Global Data Synchronization Network (GDSN); and partially overlaps the areas of Identity Management System (IdM), Business Intelligence systems, data quality, and data integration. This broad area of potential application causes multiple perspectives, diversity of stakeholders, and a fair amount of confusion across clients investigating an MDM solution.
The business need for MDM is made manifest both implicitly and explicitly. Its utility tends to be obvious in efforts around conformance and auditing, accurate reporting efforts, and a single view of the customer initiatives. However, MDM is often also a hidden requirement for successful consolidation projects after mergers and acquisitions. Its value in terms of return on investment, cost savings (reduced storage, reduced analysis, development, and maintenance, etc.), increased revenue (consistent view master data, reduced time to resolution, and effective decision making), and competitive advantage (operational efficiency, improved visibility to company performance, etc.) has been well documented by multiple reputable groups and authors (AMR Research, Forrester Research, Gartner, and the Yankee Group) so we won't explore the existing benefits that the reader can easily reference. We will however discuss the benefits of MDM as they relate to SOA enablement.
MDM systems can be "federated," "integrated," or "hybrid" reflecting a combination of the first two fundamental architectures. These three types of system characteristics are as:
- Federated MDM - cross references key identifying information from participating systems to implement a registry-style solution. The main benefit of a federated solution is non-intrusiveness on participating systems that maintain their original context.
- Integrated MDM - stores all master data information from all participating systems in a centralized MDM repository. This centralized repository houses the "gold copy" of all master data information. The main benefit of the integrated approach is that it provides the most complete, accurate, and consistent single view of master data.
- Hybrid MDM - stores common data elements from participating systems creating a "light gold copy" of the master data, while disparate elements are referenced from their original system of record. The benefit and drawback of the hybrid solution is the partial combination of the federated and integrated benefits.
From a systems design perspective, SOA is an architectural approach based on distributed computing principles. SOA has numerous other aspects in topics as diverse as business process design and IT governance. However, these aspects go beyond our scope here.
As an architectural paradigm, the participating components of a SOA system include: service providers, service consumers, intermediary services, and registries. A service provider publishes a service in the registry to be consumed by a service consumer who can identify the interface, purpose, and location of the service from the registry. Intermediary services intercept and handle operations that are common across services and can be leveraged instead of recreated every time. Typical intermediary services include: authentication, auditing, logging, monitoring, and message routing. All communications are done through commonly agreed on standards (UDDI, SOAP, WSDL, XML, HTTP/SSL). The design principles governing SOA are primarily object-oriented paradigms extended to address the service-oriented requirements. These service design principles include: loose coupling, service contract, abstraction, composability, autonomy, reusability, statelessness, and discoverability.
Services access information from a data services layer. A data services layer provides an abstraction layer between producers and consumers of data. The data services layer presents consumers with a virtual aggregated view of data from multiple data sources in a consistent and centralized fashion. The layer's interface supports all consumers (human, application, external parties, or business services) while providing agility to data source providers.
A data service layer offers many benefits. Consumers are insulated from complexity, location, and changes in source data systems through abstraction. Providers have the flexibility to change underlying data schemas without impacting consumers through abstraction. Companies can centrally manage, monitor, measure, and report on the enterprise view of the data and metadata.
The three main categorizations of services in the data services layer are: Enterprise Data Services, Enterprise Metadata Services, and Enterprise Data Platform Services.
- The Enterprise Data Services area encompasses all the services around the data. For example, a request to be addressed by this area would be: Retrieve "gold copy" of "customer A" record.
- The Enterprise Metadata Services area includes all the services around the metadata. This area would address items such as: Retrieve master data schema of "customer A" record.
- The Enterprise Data Platform Services area supports all the services around the platform including management, monitoring, and reporting. An example of a request here would be: Retrieve MDM system, quality of service targets.
MDM Meets SOA
MDM and SOA evolved separately but share many design principles.
- "Contract first" applies to the interfaces in MDM and the service definition in SOA
- "Reusability" applies to data through conformance in MDM and services through SOA principles in SOA
- "Discoverability" applies to data through the master data repository in MDM and services through registry in SOA
- "Abstraction" applies to source system complexity and MDM and underlying service complexity under SOA.
As MDM practitioners contemplating supporting today's SOA systems, we need to become familiar with SOA standards and strive for loose coupling with external systems. Eliminating point-to-point interfaces and replacing them with service-enabled integration minimizes the impact of changes from integration partners and consumers. Loose coupling should be applied internally as well to create an agile MDM system. An agile service-oriented MDM system provides its data quality, conformance, and other MDM functionality as business or data "services" available for net-enabled consumption by external parties. Finally, MDM systems should be able to handle the extensible data types (XML, HTML, PDF, and e-mail) common to net-centric application and be able to expose the master data model as part of the enterprise canonical data model (CDM) for service consumption.
Today we can collect lots and lots of performance data. We build beautiful dashboards and even have fancy query languages to access and transform the data. Still performance data is a secret language only a couple of people understand. The more business becomes digital the more stakeholders are interested in this data including how it relates to business. Some of these people have never used a monitoring tool before. They have a question on their mind like “How is my application doing” but no id...

A Man in the Middle attack, or MITM, is a situation wherein a malicious entity can read/write data that is being transmitted between two or more systems (in most cases, between you and the website that you are surfing). MITMs are common in China, thanks to the “Great Cannon.” The “Great Cannon” is slightly different from the “The Great Firewall.” The firewall monitors web traffic moving in and out of China and blocks prohibited content. The Great Cannon, on the other hand, acts as a man in the...

This recent research on cloud computing from the Register delves a little deeper than many of the "We're all adopting cloud!" surveys we've seen. They found that meaningful cloud adoption and the idea of the cloud-first enterprise are still not reality for many businesses. The Register's stats also show a more gradual cloud deployment trend over the past five years, not any sort of explosion. One important takeaway is that coherence across internal and external clouds is essential for IT right n...
