  1. Introduction to theZachman Framework Jim Carpenter President, DAMA-NCR May 11, 1999 Program Version 1.04 dated 5/13/99 8 AM

  2. What is a Framework? • Essential supporting structure(Oxford Desk Dictionary and Thesaurus) • A simple model of an entire subject • A simple classification system of an entire subject Simple: • essential concepts • uncluttered graphical representation

  3. Uses of Frameworks • Memorization (mnemonic device) • Locating (user interface) • Communication (frame a discussion) • Design (how things fit together) • Innovation (suggest new ideas)

  4. Zachman Framework:Motivation • Types of documentation needed by • Building Architects • Manufacturers • Information Systems (IS) Designers • Many types of descriptions are not used in IS • Concentration on data models & process models • Each type of document is a limited view • Limited types of documentation gives limited perspective

  5. Zachman Framework • A Classification Matrix • Classifies all kinds of Descriptive Representations • Some types of Descriptive Representations • Document • Model • List • Dictionary • Model - my preferred generic term for all of above • Statements in a modeling language • Language = fixed set of concepts with representation

  6. Zachman Framework:Classification Matrix • Columns: the six interrogatives • What, How, Where, Who, When, Why • (Data, Function, Network, People, Time, Motivation) • Rows: Roles in the development process • Note: role names vary by context. • Planner - Objectives/Scope • Owner - Enterprise Model • Designer - IS Model • Builder - Tech Model • Subcontractor - Detailed Representations • System - Functioning System

  7. Impact • IS includes more than data and function • Importance of the different players and their perspectives • Search for new forms of description and better integration • exciting new developments to be covered in future programs

  8. The ZF Phenomenon • The ZF is a model with only 2 dimensions (36 cells) • The 6 types of questions • The 6 types of roles • How does such a simple model create such a phenomenal impact? Answer: • Exhaustive coverage of two orthogonal dimensions • The classified objects (descriptive artifacts) are critical to success of any type of project. • Highly extensible in many other dimensions • Discussions usually fail to clearly identify the orthogonal dimensions (such as languages, methods, failures (thanks M.G.), tests).

  9. Classification of Today’s Topics • Metadata Registry Standards • Current version • Column 1 • Rows 1 - 6 • Next version (direction of) • Columns 1 - 6 • Rows 1 - 6 • SQL Programmer • Column 1 • Row 3 & 4

  10. Classification of Audience ? • Data Modelers (col 1, rows 2-4) • Process Modelers (col 2, rows 2-4) • Managers (row 2, all rows) • emphasis on col 5! • CIOs (row 1) • Programmers (row 4 & 5) • Data base administrators (row 4, col 1) • ...
