資源簡介
網(wǎng)絡(luò)數(shù)據(jù)庫(Network Database)其含義有三個：①在網(wǎng)絡(luò)上運行的數(shù)據(jù)庫。②網(wǎng)絡(luò)上包含其他用戶地址的數(shù)據(jù)庫。③信息管理中，數(shù)據(jù)記錄可以以多種方式相互關(guān)聯(lián)的一種數(shù)據(jù)庫。網(wǎng)絡(luò)數(shù)據(jù)庫和分層數(shù)據(jù)庫相似，因為其包含從一個記錄到另一個記錄的前進。與后者的區(qū)別在于其更不嚴格的結(jié)構(gòu)：任何一個記錄可指向多個記錄，而多個記錄也可以指向一個記錄。實際上，網(wǎng)絡(luò)數(shù)據(jù)庫允許兩個節(jié)點間的多個路徑，而分層數(shù)據(jù)庫只能有一個從父記錄（高級記錄）到子記錄（低級目錄）的路徑。
