{"product_id":"bitemporal-databases-canan-eren-atay-9783639131871","title":"Bitemporal Databases","description":"All mainstream database systems lack support for temporal metadata, and instead store only the most recent data. Consequently, they can only manage temporal data in an ad hoc manner -- oftentimes not effectively. Yet there are countless application domains that need temporal data. This book offers a much-needed solution: It includes a bitemporal relational data model, based on nested relations, as well as its algebra and calculus languages for expressing queries. The fundamental construct for representing temporal data is a bitemporal atom; a value, its validity period, and the time this data was recorded in the database. The concept of 'context' defines different views of bitemporal data. BtSQL, a simple bitemporal variation of the SQL, is introduced. The book also provides a prototype implementation, which demonstrates the feasibility of the proposed approach in an object-relational database system. Researchers and practitioners in database development will find this book useful. It can be used as a textbook in advanced database courses -- particularly in application domains where temporal metadata can greatly leverage the value of the data as it is stored and utilized.\u003cbr\u003e\u003cbr\u003e\u003cb\u003eAuthor:\u003c\/b\u003e Canan Eren Atay,Abdullah Uz Tansel\u003cbr\u003e\u003cb\u003eISBN-10:\u003c\/b\u003e 3639131878\u003cbr\u003e\u003cb\u003eISBN-13:\u003c\/b\u003e 9783639131871\u003cbr\u003e\u003cb\u003ePublisher:\u003c\/b\u003e VDM Verlag\u003cbr\u003e\u003cb\u003eLanguage:\u003c\/b\u003e English\u003cbr\u003e\u003cb\u003ePublished:\u003c\/b\u003e 03\/03\/2009\u003cbr\u003e\u003cb\u003ePages:\u003c\/b\u003e 176\u003cbr\u003e\u003cb\u003eFormat:\u003c\/b\u003e Paperback\u003cbr\u003e\u003cb\u003eWeight:\u003c\/b\u003e 0.59lbs\u003cbr\u003e\u003cb\u003eSize:\u003c\/b\u003e 9.00h x 6.00w x 0.41d","brand":"Canan Eren Atay","offers":[{"title":"Paperback","offer_id":48454052348159,"sku":"9783639131871","price":73.44,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0662\/2982\/9887\/files\/img_99a47530-39fd-4b5e-9e42-5883fc20167b.jpg?v=1777303898","url":"https:\/\/www.whiterainbookhouse.com\/products\/bitemporal-databases-canan-eren-atay-9783639131871","provider":"WR Book House","version":"1.0","type":"link"}
