移動(dòng)對(duì)象管理

內(nèi)容概要

　　隨著移動(dòng)通信技術(shù)的不斷發(fā)展和普及，人們對(duì)移動(dòng)對(duì)象管理的需求越來越迫切。移動(dòng)對(duì)象管理成為數(shù)據(jù)庫(kù)研究領(lǐng)域的一個(gè)熱門方向，它在許多領(lǐng)域都展現(xiàn)了廣闊的應(yīng)用前景。《移動(dòng)對(duì)象管理：模型、技術(shù)與應(yīng)用》比較系統(tǒng)地介紹了移動(dòng)對(duì)象管理的相關(guān)內(nèi)容，即移動(dòng)對(duì)象管理模型（包括移動(dòng)對(duì)象建模、移動(dòng)對(duì)象更新、移動(dòng)對(duì)象索引等），移動(dòng)對(duì)象管理技術(shù)（包括移動(dòng)對(duì)象查詢、移動(dòng)對(duì)象預(yù)測(cè)、移動(dòng)數(shù)據(jù)不確定性研究等），移動(dòng)對(duì)象管理應(yīng)用（包括動(dòng)態(tài)交通導(dǎo)航、動(dòng)態(tài)交通網(wǎng)絡(luò)、移動(dòng)對(duì)象聚類分析、位置隱私保護(hù)等）?！　　兑苿?dòng)對(duì)象管理：模型、技術(shù)與應(yīng)用》總結(jié)了國(guó)內(nèi)外有關(guān)移動(dòng)數(shù)據(jù)管理的研究工作和具有代表性的關(guān)鍵技術(shù)，并較詳細(xì)地介紹了作者近年來的一些研究成果，具有較大的參考價(jià)值?！　　兑苿?dòng)對(duì)象管理：模型、技術(shù)與應(yīng)用》的讀者對(duì)象為高等院校計(jì)算機(jī)專業(yè)的本科生、研究生、教師，科研機(jī)構(gòu)的研究人員以及相關(guān)領(lǐng)域的開發(fā)人員等。
