a data virtualization layer that provides transparent access to disparate and distributed data sources would meet this requirement 構(gòu)建一個(gè)能夠透明地訪問異構(gòu)和分布式數(shù)據(jù)源的數(shù)據(jù)虛擬化層,就可以實(shí)現(xiàn)上述要求。
data virtualization is provided by a software layer through which applications have transparent access to local and remote data sets 數(shù)據(jù)虛擬化是由軟件層提供的,所以應(yīng)用程序可以通過該軟件透明地訪問本地和遠(yuǎn)程數(shù)據(jù)集。
by means of data virtualization, all data sets that applications can access appear to belong to one single data store, which all r d sites can access 通過數(shù)據(jù)虛擬化的方式,應(yīng)用程序可以訪問的所有數(shù)據(jù)集看上去都像是屬于一個(gè)數(shù)據(jù)源,而所有的r&d都可以訪問該數(shù)據(jù)源。
these interfaces support the concept of data virtualization and provide mechanisms related to distributed access to information of many types including databases, files, documents, content stores, and application-generated streams 這些接口支持?jǐn)?shù)據(jù)虛擬化的概念,并提供與多種類型的信息的分布式訪問相關(guān)的機(jī)制,包括數(shù)據(jù)庫、文件、文檔、內(nèi)容庫和應(yīng)用程序生成的流。
