Data Warehousing Technology: Focus on Clinical Warehousing

This is the summary of a talk I gave as part of a workshop on Clinical Data Warehousing, at the American Medical Informatics Association (AMIA) Fall Symposium at Orlando, Florida, Nov 8th, 1998.
Introduction

• A Data Warehouse is a collection of data that reflects all aspects of an organization's operations
• A Data Mart deals with a single aspect of the data.
