Taschenbuch. Condición: Neu. nach der Bestellung gedruckt Neuware - Printed after ordering - All mainstream database systems lack support fortemporal metadata, and instead store only the mostrecent data. Consequently, they can only managetemporal data in an ad hoc manner -- oftentimes noteffectively. Yet there are countless appl…icationdomains that need temporal data. This book offers amuch-needed solution: It includes a bitemporalrelational data model, based on nested relations, aswell as its algebra and calculus languages forexpressing queries. The fundamental construct forrepresenting temporal data is a bitemporal atom; avalue, its validity period, and the time this datawas recorded in the database. The concept of context defines different views of bitemporal data.BtSQL, a simple bitemporal variation of the SQL, isintroduced. The book also provides a prototypeimplementation, which demonstrates the feasibility ofthe proposed approach in an object-relationaldatabase system. Researchers and practitioners indatabase development will find this book useful. Itcan be used as a textbook in advanced databasecourses -- particularly in application domains wheretemporal metadata can greatly leverage the value ofthe data as it is stored and utilized.
