You cannot escape temporal data. You need to get over it, sit down and read what Tom and Randy are telling you in this book. --Joe Celko, Independent Consultant & Columnist for Intelligent Enterprise, USA The authors present an original and comprehensive conceptual approach called Asserted Versioning, which includes support for bi-temporality and is a significant advance in the theory and practice of managing time-varying data.--Richard Snodgrass, Professor of Computer Science at the University of Arizona Information technology consultants Johnston and Weis explain how to integrate time into a business data system, so that the past, present, and projected future of things can be accessed easily and quickly. Tables that show time are versioned tables, and they show how using them lowers the cost and increases the value of temporal data, data that shows change through time. They introduce temporal data management and asserted versioning, then look at designing, maintaining, and querying asserted version databases.--SciTech Book News
