DAMA Dictionary of Data Management Preface DAMA International is pleased to publish the DAMA Dictionary of Data Management. This First Edition was originally drafted as the Glossary Appendix for the DAMA Guide to the Data Management Body of Knowledge (DAMA-DMBOK Guide, a trademark of DAMA International). The DAMA-DMBOK Guide will be a “definitive introduction” to data management, summarizing data management goals, principles, processes, deliverables, roles, technology, practices and organizational/cultural issues. Development of the DAMA- DMBOK Guide began in 2006, and the DAMA Foundation expects to publish the first edition of the DAMA-DMBOK Guide in 2009. The Glossary is an important integration tool guiding collaborative development of the DAMA-DMBOK Guide. The DAMA Executive Board also realized the value of the Glossary in its own right, and urged for the early completion and publishing of the Glossary as the DAMA Dictionary of Data Management. We offer the DAMA Dictionary of Data Management, a compendium of over 850 terms, to an industry in great need of clarity in its terminology and semantics. While experts may never reach 100% agreement, we believe there is general consensus agreement with these definitions across the data management profession. We hope the First Edition will be a useful tool for data management professionals, managers and business data stewards. DAMA International and The DAMA International Foundation wish to thank Mark Mosley for this important contribution to our profession. Mark is a Principal Consultant with Enterprise Warehouse Solutions, Inc., one of the leading data management consulting firms. His volunteer efforts to produce this document on behalf of DAMA are most appreciated. There will continue to be productive and valuable discussions over the meaning and use of data management terms. This First Edition provides a baseline for these discussions. As the definitions are continually refined and clarified, DAMA intends to update and publish regularly scheduled revisions of The Dictionary of Data Management. Your comments, concerns and contributions are welcomed. Please contact the editor at DAMA- DMBOKeditorinchief@dama.org to offer your suggestions for improvement.

DAMA Dictionary of Data Management Acknowledgments Sir Isaac Newton once said, “If I have seen farther, it is by standing on the shoulders of giants.” As he said this, he also demonstrated it by paraphrasing what Robert Burton said 100 years earlier, “A dwarf standing on the shoulders of giants see farther than a giant himself.” Centuries before, a Roman poet wrote, “Pygmies placed on the shoulders of giants see more than the giants themselves.” This document was developed in this same spirit, building on the contributions made by countless data management professionals over many years. As professionals, we each continually struggle to clarify the meaning of the terms used in the publications we read, the presentations we attend and the discussions in which we participate. Over time we each build an integrated understanding, and together we come to consensus about the meaning of these terms. We advance the profession step by step as we discuss the meaning of our terms, compare our perspectives and learn from each other. The semantic challenges we face as a profession can be disheartening when progress is slow and difficult to notice. However, in the course of developing this Dictionary, I have been struck by how much consensus now exists about terms once considered more controversial. This is an indication of professional progress, achieved by the giants who precede us all. Some of those giants are well known and widely admired leaders in the field of data management. Others are relatively anonymous professionals who quietly influence their circle of colleagues. While developing this document, I surveyed several glossaries available through some of the leading data management publications and websites. My responsibility was to identify terms commonly used in the field of data management, compare definitions found in several sources, and then draft an original definition using the best ideas from each source and ensuring internal consistency with the definitions of closely related terms. No definition from any existing glossary was copied verbatim into this compendium, and no single source can be cited for a given definition. The DAMA-DMBOK Editorial Board reviewed this document, its terms and definitions, as part of its responsibility for general editorial policy guidance and review for the DAMA- DMBOK Guide (see Preface). I am deeply grateful to the members of these DAMA members for their volunteer time, effort and thoughtful feedback: Bobbie Adderson Michael Brackett Larry Burns Michael Connor Patricia Cupoli Alex Friedgan Lowell Fryman Mahesh Haryu Deborah Henderson Gil Laware James McQuade Michael G.

DAMA Dictionary of Data Management Of course there are unlimited opportunities for improvement to this document. I already recognize many shortcomings, and I am sure there many as yet unrecognized shortcomings as well. Any outright errors found are my own. I welcome your suggestions for improvements to be made in a Second Edition. Special thanks are due the Executive Boards of DAMA International and The DAMA International Foundation and the DAMA Chapter President‟s Council for their support of this endeavor. Finally, I personally wish to thank Deborah Henderson, DAMA International Foundation President, for her unwavering vision, confidence and encouragement. There could be no better sponsor for this effort. Mark Mosley Chicago, IL November 2007 Copyright © 2008 by DAMA International. All rights reserved. page viii
