David  C. Hay
David C. Hay President, Essential Strategies, Inc.

David Hay has been producing data models to support strategic and requirements planning for more than thirty years. As President of Essential Strategies International, Mr. Hay has worked in a variety of industries and government agencies. These include banking, clinical pharmaceutical research, and all aspects of oil production and processing. Projects entailed defining corporate information architecture, identifying requirements, and planning strategies for the implementation of new systems.

Mr. Hay's most recent book, "Achieving Buzzword Compliance: Data Architecture Language and Vocabulary," applies the concepts of consistent vocabulary to the data architecture field itself.
Previously, Mr. Hay wrote, "Enterprise Model Patterns: Describing the World," an "upper ontology" consisting of a comprehensive model of any enterprise. It is the successor to his ground-breaking 1995 book, "Data Model Patterns: Conventions of Thought"—the original book describing standard data model configurations for standard business situations.

In addition, Mr. Hay has written other books on metadata, requirements analysis, and UML. He has spoken at numerous international and local data architecture, semantics, user group, and other conferences.
