2、時(shí)、高效的內(nèi)存數(shù)據(jù)庫(kù)(MMDB)系統(tǒng)。與外存數(shù)據(jù)庫(kù)相比,內(nèi)存數(shù)據(jù)庫(kù)最大的特點(diǎn)是數(shù)據(jù)常駐內(nèi)存,所有對(duì)數(shù)據(jù)的操作都在內(nèi)存中完成,因此對(duì)數(shù)據(jù)的組織管理方式、同步策略需要重新定義。本文根據(jù)合法偵聽(tīng)系統(tǒng)架構(gòu)的設(shè)計(jì),對(duì)數(shù)據(jù)庫(kù)模塊的功能需求進(jìn)行分析,引入面向?qū)ο蟮膬?nèi)存數(shù)據(jù)庫(kù)來(lái)滿足偵聽(tīng)系統(tǒng)對(duì)數(shù)據(jù)的實(shí)時(shí)性要求。通過(guò)對(duì)內(nèi)存數(shù)據(jù)庫(kù)的研究,本文數(shù)據(jù)庫(kù)管理系統(tǒng)的實(shí)現(xiàn)主要包括:數(shù)據(jù)的組織管理方式、數(shù)據(jù)應(yīng)用接口設(shè)計(jì)、數(shù)據(jù)同步策略的設(shè)計(jì)。數(shù)據(jù)的合理組織是實(shí)現(xiàn)數(shù)據(jù)安全、高效同步的基礎(chǔ);數(shù)據(jù)應(yīng)用接口是外界訪問(wèn)內(nèi)存數(shù)據(jù)庫(kù)的窗口;數(shù)據(jù)同步確保了內(nèi)存中數(shù)據(jù)的準(zhǔn)確性,數(shù)據(jù)同步分為靜態(tài)同步和動(dòng)態(tài)同步,
