Data-Ed: Data Systems Integration & Business Value PT. 1: Metadata

Descargar para leer sin conexión

Certain systems are more data focused than others. Usually their primary focus is on accomplishing integration of disparate data. In these cases, failure is most often attributable to the adoption of a single pillar (silver bullet). The three webinars in the Data Systems Integration and Business Value series are designed to illustrate that good systems development more often depends on at least three DM disciplines (pie wedges) in order to provide a solid foundation.

Much of the discussion of metadata focuses on understanding it and the associated technologies. While these are important, they represent a typical tool/technology focus and this has not achieved significant results to date. A more relevant question when considering pockets of metadata is: Whether to include them in the scope organizational metadata practices. By understanding what it means to include items in the scope of your metadata practices, you can begin to build systems that allow you to practice sophisticated ways to advance their data management and supported business initiatives. After a bit of practice in this manner you can position your organization to better exploit any and all metadata technologies.

  15. 15. Copyright 2013 by Data Blueprint Meta-data or metadata • In the history of language, whenever two words are pasted together to form a combined concept initially, a hyphen links them • With the passage of time, the hyphen is lost. The argument can be made that that time has passed • There is a copyright on the term "metadata," but it has not been enforced • So, term is "metadata" 15
  16. 16. Copyright 2013 by Data Blueprint Definitions • Metadata is – Everywhere in every data management activity and integral to all IT systems and applications. – To data what data is to real life. Data reflects real life transactions, events, objects, relationships, etc. Metadata reflects data transactions, events, objects, relations, etc. – The data that describe the structure and workings of an organization’s use of information, and which describe the systems it uses to manage that information. [quote from David Hay's new book, page 4] • Data describing various facets of a data asset, for the purpose of improving its usability throughout its life cycle [Gartner 2010] • Metadata unlocks the value of data, and therefore requires management attention [Gartner 2011] • Metadata Management is – The set of processes that ensure proper creation, storage, integration, and control to support associated use of metadata 16
  17. 17. Copyright 2013 by Data Blueprint Analogy: Card catalog in a library • Card catalog identifies what books are stored in the library and where they are located in the building • Users can search for books by subject area, author, or title • Catalog shows author, subject tags, publication date and revision history of each book • Card catalog information helps determine which books will meet the reader’s needs • Without this catalog resource, finding books in the library would be difficult, time consuming and frustrating • Readers may search many incorrect books before finding the right book if a catalog does not exist 17 from The DAMA Guide to the Data Management Body of Knowledge © 2009 by DAMA International
  18. 18. Copyright 2013 by Data Blueprint Definition (continued) • Metadata is the card catalog in a managed data environment • Abstractly, Metadata is the descriptive tags or context on the data (the content) in a managed data environment • Metadata shows business and technical users where to find information in data repositories • Metadata provides details on where the data came from, how it got there, any transformations, and its level of quality • Metadata provides assistance with what the data really means and how to interpret it 18 from The DAMA Guide to the Data Management Body of Knowledge © 2009 by DAMA International

  23. 23. Uses Copyright 2013 by Data Blueprint What is the structure of metadata practices? • Metadata practices connect data sources and uses in an organized and efficient manner – Storage: repository, glossary, models, lineage - currently multiple technologies are used – Engineering: identifying/harvesting/normalizing/administer evolving metadata structures – Delivery: supply/access/portal/definition/lookup search identify/ensure required metadata supplies to meet business needs – Governance: ensure proper/creation/storage/integration/control to support effective use • When executed, engineering and delivery implement governance Sources Metadata Governance Metadata Engineering Metadata Delivery Metadata Practices Metadata Storage 23 Specialized Team Skills

  38. 38. Copyright 2013 by Data Blueprint 7 Metadata Benefits 1. Increase the value of strategic information (e.g. data warehousing, CRM, SCM, etc.) by providing context for the data, thus aiding analysts in making more effective decisions. 2. Reduce training costs and lower the impact of staff turnover through thorough documentation of data context, history, and origin. 3. Reduce data-oriented research time by assisting business analysts in finding the information they need in a timely manner. 4. Improve communication by bridging the gap between business users and IT professionals, leveraging work done by other teams and increasing confidence in IT system data. 5. Increased speed of system development’s time-to-market by reducing system development life-cycle time. 6. Reduce risk of project failure through better impact analysis at various levels during change management. 7. Identify and reduce redundant data and processes, thereby reducing rework and use of redundant, out-of-data, or incorrect data. 38 from The DAMA Guide to the Data Management Body of Knowledge © 2009 by DAMA International
  39. 39. Copyright 2013 by Data Blueprint Metadata for Semistructured Data • Unstructured data – Any data that is not in a database or data file, including documents or other media data • Metadata describes both structured and unstructured data • Metadata for unstructured data exists in many formats, responding to a variety of different requirements • Examples of Metadata repositories describing unstructured data: – Content management applications – University websites – Company intranet sites – Data archives – Electronic journals collections – Community resource lists • Common method for classifying Metadata in unstructured sources is to describe them as descriptive metadata, structural metadata, or administrative metadata 39 from The DAMA Guide to the Data Management Body of Knowledge © 2009 by DAMA International
  40. 40. Copyright 2013 by Data Blueprint Metadata for Unstructured Data: Examples • Examples of descriptive metadata: – Catalog information – Thesauri keyword terms • Examples of structural metadata – Dublin Core – Field structures – Format (audio/visual, booklet) – Thesauri keyword labels – XML schemas • Examples of administrative metadata – Source(s) – Integration/update schedule – Access rights – Page relationships (e.g. site navigational design) 40
  41. 41. Copyright 2013 by Data Blueprint Specific Example • Four metadata sources: 1. Existing reference models (i.e., ADRM) 2. Conceptual model created two years ago 3. Existing systems (to be reverse engineered) 4. Enterprise data model } 41

  44. 44. Copyright 2013 by Data Blueprint Metadata History 1990-2008 • The history of Metadata management tools and products seems to be a metaphor for the lack of a methodological approach to enterprise information management: • Lack of standards and proprietary nature of most managed Metadata solutions cause many organizations to avoid focusing on metadata • This limits organizations’ ability to develop a true enterprise information management environment • Increased attention given to information and its importance to an organization’s operations and decision-making will drive Metadata management products and solutions to become more standardized • More recognition to the need for a methodological approach to managing information and metadata 44
  45. 45. Copyright 2013 by Data Blueprint Metadata History: The 1990s • Business managers began to recognize the value of Metadata repositories • Newer tools expanded the scope • Potential benefits identified during this period include: – Providing semantic layer between company’s system and business users – Reducing training costs – Making strategic information more valuable as aid in decision making – Creating actionable information – Limiting incorrect decisions 45
  46. 46. Copyright 2013 by Data Blueprint Metadata History: Mid-to late 1990s • Metadata becomes more relevant to corporations who were struggling to understand their information resources caused by: – Y2K deadline – Emerging data warehousing initiatives – Growing focus around the World Wide Web • Beginning of efforts to try to standardize Metadata definition and exchange between applications in the enterprise • Examples of standardization: – 1995: CASE Definition Interchange Facility (CDIF) – 1995: Dublin Core Metadata Elements – 1994 – 1999: First parts of ISO 11179 standard for Specification and Standardization of Data Elements were published – 1998: Common Warehouse Metadata Model (CWM) – 1995: Metadata Coalitions’ (MDC) Open Information Model – 2000: Both standards merged into CSM. Many Metadata repositories began promising adoption of CWM standard 46
  47. 47. Copyright 2013 by Data Blueprint Metadata History: 21st Century • Update of existing Metadata repositories for deployment on the web • Introduction of products to support CWM • Vendors begin focusing on Metadata as an additional product offering • Few organizations purchase or develop Metadata repositories • Effective enterprise-wide Managed Metadata Environments are rare due to: – Scarcity of people with real world skills – Difficulty of the effort – Less than stellar success of some of the initial efforts at some companies – Stagnation of the tool market after the initial burst of interest in late 90s – Still less than universal understanding of the business benefits – Too heavy emphasis on legacy applications and technical metadata 47
  48. 48. Copyright 2013 by Data Blueprint Metadata History: Current Decade • Focus on need for and importance of metadata • Focus on how to incorporate Metadata beyond traditional structured sources and include semistructured sources • Driving factors: – Recent entry of larger vendors into the market – Challenges related to addressing regulatory requirements, e.g. Sarbanes-Oxley, and privacy requirements with unsophisticated tools – Emergence of enterprise-wide initiatives, e.g. information governance, compliance, enterprise architecture, automated software reuse – Improvements to the existing Metadata standards, e.g. RFP release of new OMG standard Information Management Metamodel (IMM), which will replace CWM – Recognition at the highest levels that information is an asset that must be actively and effectively managed 48
  49. 49. Copyright 2013 by Data Blueprint Why Metadata Matters • They know you rang a phone sex service at 2:24 am and spoke for 18 minutes. But they don't know what you talked about. • They know you called the suicide prevention hotline from the Golden Gate Bridge. But the topic of the call remains a secret. • They know you spoke with an HIV testing service, then your doctor, then your health insurance company in the same hour. But they don't know what was discussed. • They know you received a call from the local NRA office while it was having a campaign against gun legislation, and then called your senators and congressional representatives immediately after. But the content of those calls remains safe from government intrusion. • They know you called a gynecologist, spoke for a half hour, and then called the local Planned Parenthood's number later that day. But nobody knows what you spoke about. – https://www.eff.org/deeplinks/2013/06/why-metadata-matters 49
  50. 50. Copyright 2013 by Data Blueprint Metadata Strategy • Metadata Strategy is – A statement of direction in Metadata management by the enterprise – A statement of intend that acts as a reference framework for the development teams – Driven by business objectives and prioritized by the business value they bring to the organization • Build a Metadata strategy from a set of defined components • Primary focus of Metadata strategy – gain an understanding of and consensus on the organization’s key business drivers, issues, and information requirements for the enterprise Metadata program • Need to understand how well the current environment meets these requirements now and in the future • Metadata strategy objectives define the organization’s future enterprise metadata architecture and recommend logical progression of phased implementation steps • Only 1 in 10 organizations has a documented, board approved data strategy 50
