Overview

"The book you are about to read is the essential guide, for once and for all making metadata management an intrinsic, immutable part of today's and tomorrow's information systems."
--Alan Simon, Deloitte Consulting, Data Warehousing Solutions Group

With the advent of data warehousing and the growing importance of data access through the Internet, it is essential for all IT professionals to be familiar with metadata. Written by one of the world's foremost information technology experts, Metadata Solutions is a practical guide to understanding and using metadata as a gateway to information. This book serves as a blueprint for designing and implementing a metadata solution that effectively handles information access and exchange within and across organizations.

Metadata Solutions offers an enlightening overview of the role of metadata within current IT trends. The author provides detailed treatment of metadata, metamodels, meta-metadata, and meta-metamodel concepts and structures. She offers in-depth descriptions of specific metadata-based technologies and standards, featuring the benefits and drawbacks of each. With a practical approach, this book presents step-by-step instructions for implementing and maintaining a metadata solution, and provides sample solutions appropriate for a variety of informational needs and circumstances. Most important, it serves as a guide for organizations that are coping with metadata.

Coverage includes the following specific topics:

  • A review of conventional approaches to information definition, design, and access (data modeling, databases, data warehousing)
  • A renewed perspective on previous attempts at data management
  • Identification and organization of metadata requirements without setting up yet another database
  • Examination of vendor, standard, and custom metamodels
  • The meta-metamodel and the impact of extensibility
  • Metadata solution components, including stores and displays
  • Types of metadata solutions, including repositories, XML-based exchange, and enterprise portals
  • The metadata roles and standards of today and tomorrow
  • Information about metadata security
  • Organizational structures for creating, managing, and maintaining the metadata solution
  • Ways to expand existing metadata solutions
  • Sample metadata solution implementations

Numerous case studies, drawn from extensive industry experience, illustrate real-world applications of metadata techniques and concepts. A typical metadata disaster scenario, with associated implementation examples, will help you identify ways to avoid common pitfalls. With this book as your guide, you will be well prepared to explore, choose, implement, and maintain a metadata solution to transform your organization's data into a more accessible and valuable resource.

Read an Excerpt

I remember when data became a specialty in its own right. No longer viewed as simply being supportive of the processes within an organization, data became an asset that led to solid decision making and improved processes. Data, which sometimes had been collected in haphazard ways, in fact, became so valuable that people were trying to logically connect sporadic and isolated data. As the attempts to unify data were taking place, we all realized that its locations, characteristics, definitions, sources, and access were becoming equally important. Hence, the "birth" of metadata.

Associating metadata solely with data does not do it justice. In fact, there are so many aspects to the world of information that metadata needs to embrace each and every one of them. Whether we realize it or not, metadata is already everywhere. All we are missing is an organized view of metadata, despite its origin. Today's world of information needs an associated metadata solution.

Many of us have already learned that metadata is everywhere, but despite this discovery, we have created more of it, in more places. It is time to make an honest assessment of the metadata efforts and begin to focus on metadata as the gateway to all information. To do that we must understand what metadata really is, where it actually comes from, and how to expand its role in the world of automated intelligence.

Few will debate the importance of metadata. It is time, then, for a book that tackles metadata in a way that will clearly lead the reader toward a metadata solution.

Intended Audience

If you have been given the task of managing your organization's information, this book is clearly for you. Likewise, if you are wondering why the data "dictionaries" or "repositories" that have been offered to you just don't seem to serve their intended roles, this book clearly explains what should have been accomplished. Because metadata is, potentially so broad, this book is meant to provide an excellent "backbone" for those who are charged with actually building a full metadata solution. The following are some of the individuals who will benefit the most from this approach.

  • Chief information and/or technology officers who are responsible for assessing the metadata situation within their organizations with the objective of beginning a full, practical, metadata solution implementation process
  • Business users who have experienced data inaccuracy, lack of available metadata, and a general inability to find the information they need
  • Information technology project managers who are responsible for overseeing the design and development of any data-intense application. Examples include a data warehouse, integrated database, decision support application, customer relationship management application, reengineered series of legacy databases, and/or any type of project that requires an assessment of "what is," with the objective of planning a "to be" improvement.
  • Data management professionals who are responsible for the administration, standardization, sharing, and organization of corporate data, especially those with previous experiences that resulted in unsuccessful repository or metadata solution implementations
  • Developers, especially those who are faced with integrating or analyzing existing corporate applications
  • Software vendors that are struggling with a need to supply standard metadata to product consumers while integrating their own software into a metadata accessible result
  • Consulting professionals, particularly those who have faced implementation issues at client companies due to the lack of readily available and accurate metadata

This book provides information and content that will enlighten all of these individual groups. The next section describes some aspects of the book that may appear to be quite technical.

How This Book Is Organized

Consider Metadata Solutions: Using Metamodels, Repositories,

as the first book to address the metadata situation from the beginning through to a practical solution and then into its future maintenance and enhancement. As such, the book has been divided into six parts.

Part I, Today's Information, prepares readers for the book's subsequent discussion of metadata. By looking at information in a way that many may never have considered, this part provides an overview of information and its many existing perspectives. Then, the information problems that have surfaced are discussed. Finally, this part reviews information solutions that have been tried, and for the most part are still in existence, and explains where they fell short. At the conclusion of Part I, the reader should be ready to discuss metadata. Many experienced information practitioners can skip this part, but even with information integration experience, some eyes may still be opened.
Part II, Metadata as Part of the Solution, begins the discussion of metadata itself. First, a solid definition of today's buzzword focuses readers on how tunnel vision can even affect cross-application concepts such as metadata. The part begins the metadata requirements process. By stepping you through a methodology that first identifies metadata beneficiaries, determines metadata requirements, and then begins a categorization process, Part II gets the reader used to metamodels. Metadata stores—the physical storage locations for metadata—are also discussed, giving you various options as to how metamodels can be implemented. As a way of reminding the reader that metadata solutions are much more than the storage of metamodels, the metadata solution architecture is the last topic discussed in the part.
Part III, Entering Meta-Meta Land, takes us inside the metadata solution. To deal with the fact that metadata is everywhere, a true metadata solution needs to be cognizant of the location and access requirements of existing metadata. In addition, metadata solutions all process and display their metadata differently based on the type of metadata. Designers and developers of true metadata solutions must be able to treat metadata with a software perspective. Part III focuses on what metadata means to a tool and discusses the meta-metamodel. Once this basic understanding is covered, metadata-based technologies, such as repositories, the Web,
Part IV, Beginning the Metadata Solution Process, discusses implementation-specific aspects, other than the metadata and its associated metamodels. Nontechnical factors, such as readiness, scoping, and internal environment changes, are addressed at the beginning of this part. The discussion then moves to technical factors—multitool architecture, metadata update and exchange, metadata presentation. A chapter is dedicated to metadata solution technical support, specifically metadata and repository administration. Part IV ends with advice on determining the right solution.
Part V, Sample Metadata Solutions, begins with a case study—A Typical Metadata Disaster—that equates to a very common metadata situation within corporate America. Succeeding chapters illustrate actual metadata solution implementations that are all focused on solving the identified disaster. Illustrated solutions (often including actual program code, metamodels, and architectural diagrams) include a centralized repository, an integrated repository architecture, an information directory, metadata-interexchange using
Part VI, Maintaining the Metadata Solution, describes how the metadata solution stays alive. One way is by ensuring that it meets the requirements of its targeted beneficiaries. This final part discusses the organizational responsibilities that go along with such a task; it also focuses on how to ensure the livelihood of the metadata itself by discussing metadata quality. The book closes by pointing out where metadata meets the business strategy, now and into the future.
Reading Paths

Implementing a metadata solution involves a variety of skills, from business analysis all the way through to technical application and interface development. As such, the chapters in this book range in terms of primary audience and interest level. Those chapters that are geared purely to those responsible for hands-on metadata solution delivery because they contain sample code or metadata solution internals have been labeled Technical at the upper right corner of the first page in each chapter.

To accommodate the different backgrounds of this book's readers, I have set up the following reader categories and noted the chapters that will be of interest.

  • Information systems management people who need to be aware of the intricacies of metadata solutions, but have not planned to have any hands-on involvement:
    − Part 1 - all chapters
    − Part 2 - all chapters
    − Part 3 - Chapters 15 and 16
    − Part 4 - all chapters
    − Part 5 - Chapters 21, 24, and 25
    − Part 6 - all chapters
    • Business users who crave a well-implemented metadata solution
    − Part 1 - all chapters
    − Part 2 - Chapters 7, 8, and 9
    − Part 3 - Chapters 15 and 16
    − Part 4 - Chapters 17 and 20
    − Part 5 - Chapter 21
    − Part 6 - all chapters
    • Technical analysts, and developers who are familiar with database technology
    − Part 1 - Chapters 1, 2, and 6
    − Part 2 - all chapters
    − Part 3 - all chapters
    − Part 4 - all chapters
    − Part 5 - all chapters
    − Part 6 - all chapters
    • Data management professionals who are familiar with metadata and its current treatment
    − Part 1 - Chapters 1, 4, 5, and 6
    − Part 2 - all chapters
    − Part 3 - Chapter 12, 14, 15, and 16
    − Part 4 - all chapters
    − Part 5 - all chapters
    − Part 6 - all chapters
Model Legend Throughout the book, various models are used to illustrate metadata relationships, metamodels, and metadata flows. Because, unfortunately, there really is no uniform way of depicting models these days, a figure that shows the various symbols you will see in this book will be printed on the inside cover.

Most of the illustrations in this book follow my default modeling characteristics, at the top of the figure. However, because other illustrations and models have been brought in from other sources, it is important to understand their notations, as depicted. The Unified Modeling Language (UML) is the standard followed by the Object Management Group (OMG).

What Is Your Objective?

As you read this book, you should be correlating the described metadata situations with those of your own. Actual case studies, submitted by large organizations that have lived through metadata-related situations, are used throughout the book. You should consider how a renewed metadata perspective, like the one discussed throughout this book, can revitalize the metadata that exists at your organization. Readers should expect to gain enough knowledge to move forward on a hands-on metadata solution implementation of any scope.

Because, unfortunately, there really is no uniform way of depicting models these days, a figure that shows the various symbols you will see in this book will be printed on the inside cover.

        Most of the illustrations in this book follow my default modeling characteristics, at the top of the figure. However, because other illustrations and models have been brought in from other sources, it is important to understand their notations, as depicted. The Unified Modeling Language (UML) is the standard followed by the Object Management Group (OMG).

        What Is Your Objective?

        As you read this book, you should be correlating the described metadata situations with those of your own. Actual case studies, submitted by large organizations that have lived through metadata-related situations, are used throughout the book. You should consider how a renewed metadata perspective, like the one discussed throughout this book, can revitalize the metadata that exists at your organization. Readers should expect to gain enough knowledge to move forward on a hands-on metadata solution implementation of any scope.

    Defines Metadata

    Tannenbaum clearly knows the data storage and mining industry. She has produced a book that brings together a comprehensive view of metadata and of its parent, meta-metadata. It is rather easy to find a book on the details of XML, for example. Or on SQL and its various commercial and open source implementations. And on database design. But all these can be regarded as lower level details. What if you have several data warehouses, each with its own DBMS catalog, and the warehouses are not from the same vendor? Plus, there are manifold, quite separate application tools that read/write to these. You want to develop a coherent integrated view of the data, hopefully by using metadata descriptors. The type of texts mentioned above are of little help here. The vendor specific books typically orient you to their product alone. Tannenbaum has striven to fill this market gap. She explains what metadata is, and what a metamodel is. All done at a high level that frees you from the syntax of XML or SQL. Though she does use UML in many diagrams, you do not need to know UML to understand them. My only quibble is that perhaps some more detailed examples would have been instructive. The high level discussions are good. But some readers might miss the significances of some remarks. More explicit pedagogic examples might drive home the points.

    Convinced the hard way

    I was never a big fan of what I call the 'let them do their own thing' approach. This book showed me why all of the data management things that I tried didn't work, and now I hate to admit that Adrienne T. is right. She shows how to make the best of what you already have....data finally comes together despite its multiple renditions. Thank you AT for finally telling me not to try for the perfect world
