Data Model Patterns: A Metadata Map (Hardcover)

Description

In recent years, companies and government agencies have come to realize that the data they use represent a significant corporate resource, whose cost calls for management every bit as rigorous as the management of human resources, money, and capital equipment. With this realization has come recognition of the importance to integrate the data that has traditionally only been available from disparate sources. An important component of this integration is the management of the ?metadata? that describe, catalogue, and provide access to the various forms of underlying business data. The ?metadata repository? is essential keeping track both of the various physical components of these systems, but also their semantics. What do we mean by ?customer?? Where can we find information about our customers? After years of building enterprise models for the oil, pharmaceutical, banking, and other industries, Dave Hay has here not only developed a conceptual model of such a metadata repository, he has in fact created a true enterprise data model of the information technology industry itself. - The book is comprehensive, in that it is based on the Zachman Framework for information architecture?encompassing the Business Owner?s, Architect?s, and Designer?s views, for all columns (data, activities, locations, people, timing, and motivation). - The book is comprehensible, in that it provides a step-by-step description of model and is organized so that different readers can benefit from different parts;. - The book takes advantage of the author?s vast experience modeling various other industries; - The model provides a view of the world being addressed by all the techniques, methods and tools of the information processing industry (for example, object-oriented design, CASE, business process re-engineering, etc.). - Indeed it presents many concepts that are not currently being addressed by such tools?and should be. David C. Hay is founder of Essential Strategies, Inc., a consulting firm dedicated to helping clients define corporate information architecture, identify requirements, and plan strategies for the implementation of new systems, including data warehouses. A pioneer in the use of standard data models for standard business situations, he is the author of the book Data Model Patterns: Conventions of Thought. Taking advantage of thirty years? experience helping companies identify systems requirements, he is also the author of Requirements Analysis: From Business Views to Architecture. He is a member of DAMA International and the Oracle Development Tools User Group, and has spoken frequently at events sponsored by these groups and others.

描述

近年來，企業和政府機構已經意識到他們使用的數據代表著一個重要的企業資源，其成本需要像人力資源、金錢和資本設備一樣嚴格管理。隨著這一認識的出現，人們開始認識到將傳統上只能從不同來源獲取的數據整合起來的重要性。這種整合的一個重要組成部分是管理描述、目錄和提供對各種底層業務數據的訪問的“元數據”。“元數據庫”是跟踪這些系統的各種物理組件以及它們的語義的重要組成部分。我們所說的“客戶”是什麼意思？我們在哪裡可以找到有關客戶的信息？在為石油、制藥、銀行和其他行業建立企業模型多年後，Dave Hay不僅開發了這樣一個元數據庫的概念模型，而且實際上創建了一個真正的信息技術行業的企業數據模型。- 本書是全面的，因為它基於Zachman框架的信息架構，涵蓋了所有列（數據、活動、位置、人員、時間和動機）的業務所有者、架構師和設計師的觀點。- 本書是易於理解的，因為它提供了對模型的逐步描述，並且組織得不同的讀者可以從不同的部分中受益。- 本書利用了作者在建模其他行業方面的豐富經驗；- 這個模型提供了一個視圖，涉及到信息處理行業的所有技術、方法和工具（例如，面向對象設計、CASE、業務流程再造等）。- 事實上，它提出了許多目前這些工具尚未解決的概念，但應該解決的問題。David C. Hay是Essential Strategies, Inc.的創始人，該公司是一家致力於幫助客戶定義企業信息架構、確定需求並計劃實施新系統（包括數據倉庫）的咨詢公司。作為在標準業務情景中使用標準數據模型的先驅，他是書籍《數據模型模式：思維慣例》的作者。利用30年的經驗幫助公司確定系統需求，他還是《需求分析：從業務視圖到架構》的作者。他是DAMA國際和Oracle開發工具用戶組的成員，並經常在這些組織和其他組織贊助的活動上發表演講。
