The pain that organizations are experiencing around consistent reporting Josh Martin Jersey , regulatory compliance, strong interest in Service-Oriented Architecture (SOA) and Software as a Service (SaaS) has prompted a great deal of interest in Master Data Management (MDM) solutions. This article explains what MDM is all about and how to implement it, while identifying some of the key MDM management patterns and techniques which are emerging.
What is Master Data Management?
There are some very well-understood and easily identified master-data items, such as "customer" and "product." In fact, many define master data by simply reciting a commonly agreed upon master-data item list, such as: customer, product, location Terrence Brooks Jersey , employee, and asset. But how you identify elements of data that should be managed by a master-data management system is much more complex and defies such rudimentary definitions. In fact, there is a lot of confusion around what master data is and how it is qualified, necessitating a more comprehensive treatment. There are essentially five types of data in corporations:
• Unstructured: This is data found in e-mail, white papers like this, magazine articles, corporate intranet portals, product specifications Kony Ealy Jersey , marketing collateral, and PDF files.
• Transactional: This is data related to sales, deliveries, invoices, trouble tickets, claims, and other monetary and non-monetary interactions.
• Metadata: This is data about other data and may reside in a formal repository or in various other forms such as XML documents, report definitions DeMario Davis Jersey , column descriptions in a database, log files, connections, and configuration files.
• Hierarchical: Hierarchical data stores the relationships between other data. It may be stored as part of an accounting system or separately as descriptions of real-world relationships, such as company organizational structures or product lines. Hierarchical data is sometimes considered a super MDM domain, because it is critical to understanding and sometimes discovering the relationships between master data.
• Master: Master data are the critical nouns of a business and fall generally into four groupings: people, things, places Chandler Catanzaro Jersey , and concepts. Further categorizations within those groupings are called subject areas, domain areas, or entity types. For example, within people, there are customer, employee, and salesperson. Within things, there are product Kelvin Beachum Jersey , part, store, and asset. Within concepts, there are things like contract, warrantee, and licenses. Finally, within places, there are office locations and geographic divisions. Some of these domain areas may be further divided.
To summarize ArDarius Stewart Jersey , while it is simple to enumerate the various master-data entity types, it is sometimes more challenging to decide which data items in a company should be treated as master data. Often, data that does not normally comply with the definition for master data may need to be managed as such, and data that does comply with the definition may not. Ultimately, when deciding on what entity types should be treated as master data, it is better to categorize them in terms of their behavior and attributes within the context of the business needs than to rely on simple lists of entity types.
Excavating the Master Data Management (MDM) Implementation Strategies:
• Identify Sources Of Master Data: This step is usually a very revealing exercise. Some companies find they have dozens of databases containing customer data that the IT department did not know existed.
• Identify The Producers And Consumers Of The Master Data: Which applications produce the master data identified in the first step, and—generally more difficult to determine—which applications use the master data. Depending on the approach you use for maintaining the master data, this step might not be necessary. For example Marcus Maye Jersey , if all changes are detected and handled at the database level, it probably does not matter where the changes come from.
• Collect And Analyze Metadata About For Your Master Data: For all the sources identified in step one, what are the entities and attributes of the data, and what do they mean? This should include attribute name, datatype, allowed values, constraints, default values Jamal Adams Jersey , dependencies, and who owns the definition and maintenance of the data.
• Appoint Data Stewards: These should be the people with the knowledge of the current source data and the ability to determine how to transform the source into the master-data format. In general, stewards should be appointed from the owners of each master-data source.
• Develop The Master-Data Model: Decide what the master records look like: what attributes are included, what size and data type they are, what values are allowed, and so forth. This step should also include the mapping between the master-data model and the current data sources
• Choose A Toolset: You will need to buy or build tools to create the master lists by cleaning, transforming, and merging the source data. You will also need an infrastructure to use and maintain the master list. These functions are covered in detail later in the paper.
• Design the Infrastructure: Once you have clean Jordan Jenkins Jets Jersey , consistent master data, you will need to expose it to your applications and provide processes to manage and maintain it.
• Generate And Test The Master Data: This step is where you use the tools you have developed or purchased to merge your source data into your master-data list. This is often an iterative process requiring tinkering with rules and settings to get the matching right. This process also requires a lot of manual inspection to ensure that the results are correct and meet the requirements established for the project.
• Modify The Producing And Consuming Systems: Depending on how your MDMOne of the biggest.
