Time Granularities in Databases, Data Mining, and Temporal Reasoning / Edition 1

Overview

Calendar units, such as months and days, clock units, such as hours an d seconds, and specialized units, such as business days and academic y ears, play a major role in a wide range of information system applicat ions. System support for reasoning about these units, called granulari ties in this book, is important for the efficient design, use, and imp lementation of such applications. The book deals with several aspects of temporal information and provides a unifying model for granularitie s. It is intended for computer scientists and engineers who are intere sted in the formal models and technical development of specific issues . Practitioners can learn about critical aspects that must be taken in to account when designing and implementing databases supporting tempor al information. Lecturers may find this book useful for an advanced co urse on databases. Moreover, any graduate student working on time repr esentation and reasoning, either in data or knowledge bases, should de finitely read it.
