A veteran of the Information Industry since the days of punched cards, paper tape, and teletype machines, Dave Hay has been producing data models to support strategic information planning and requirements planning since the mid-1980's. He has worked in a variety of industries, including, among others, power generation, clinical pharmaceutical research, upstream and downstream oil production and processing, forestry, banking, foster care, and broadcast. He is the founder and President 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.
A pioneer in the requirements analysis field, he has written Requirements Analysis: From Business Views to Architecture, published by Prentice Hall.
The first to promote the use of standard data models for standard business situations, he is also the author of the book, Data Model Patterns: Conventions of Thought, published by Dorset House. More recently, he has produced Data Model Patterns: Data Architecture in a Box™, an Oracle Designer repository containing his model templates.
In 2006, he has published the definitive description of a metadata schema, that can be used as the basis for designing a metadata repository. It is in the form of a conceptual enterprise model for the Information Technology industry, encompassing all six rows and three and a half columns of Dave's version of the Zachman Framework.
A member of the Data Administration Management Association (DAMA International), Mr. Hay participates frequently as a speaker at both international and local events. He is also active in various Oracle user groups, and writes frequently for The Data Administration Newsletter (http://www.tdan.com). He is a former member of the Business Rules Group.
Mr. Hay lives in Houston with his wife, Jola. His children, Pamela and Bob are now pursuing careers in London and New York City, respectively. In his spare time, he pursues the ancient Japanese art of Origami. He can fold a square piece of paper into a flower, a dinosaur, or any of myriad other figures—without any cutting, pasting, or swearing. For a more personal view of him, go to
