Examples of important applications of RTDBS include stock trading systems, navigation systems and computer integrated manufacturing. Different transaction scheduling algorithms and concurrency control protocols have been proposed to satisfy transaction timing data temporal constraints. Other design issues important to the performance of a RTDBS are buffer management, index accesses and I/O scheduling. Real-Time Database Systems: Architecture and Techniques summarizes important research results in this area, and serves as an excellent reference for practitioners, researchers and educators of real-time systems and database systems.Kluwer international series in engineering and computer science ;SECS 593.Database designReal-time data processingElectronic books.Database design.Real-time data processing.004/.33Lam Kam-Yiu1964-851206Kuo Tei-Wei851207MiAaPQMiAaPQMiAaPQBOOK9910454833303321Real-time database systems1900575UNINA04363nam 22005774a 450 991078000590332120230607213814.00-309-13304-11-280-18472-897866101847290-309-51284-0(CKB)111069351122136(OCoLC)559496531(CaPaEBR)ebrary10032405(SSID)ssj0000283953(PQKBManifestationID)12052338(PQKBTitleCode)TC0000283953(PQKBWorkID)10250771(PQKB)10833339(MiAaPQ)EBC3375210(Au-PeEL)EBL3375210(CaPaEBR)ebr10032405(CaONFJC)MIL18472(OCoLC)923254712(EXLCZ)9911106935112213620020227d2002 uy 0engurcn|||||||||txtccrAbrupt climate change[electronic resource] inevitable surprises /Committee on Abrupt Climate Change, Ocean Studies Board, Polar Research Board, Board on Atmospheric Sciences and Climate, Division on Earth and Life Studies, National Research CouncilWashington, D.C.
