design of heterogeneous distributed database query system based on layering thought 基于分層思想的異構(gòu)分布式數(shù)據(jù)庫查詢設(shè)計
querying the dynamic network database query system of this website is very easy, convenient, well timely and has good intercommunication 本網(wǎng)站所開發(fā)的農(nóng)業(yè)水土工程信息數(shù)據(jù)庫,數(shù)據(jù)查詢操作簡單,具有很好的動態(tài)交互性、及時性和便捷性。
using nlu technology in the database query system and designing nlqid ( natural language query interface of database ) has become one of the most hopeful applied fields in the research on nlu 在數(shù)據(jù)庫查詢系統(tǒng)中應用自然語言理解技術(shù),設(shè)計數(shù)據(jù)庫自然語言查詢接口,已成為自然語言研究中最具有廣泛應用前景的方向之一。
more generally, in this paper, we provided a global database query system which based on several database query systems and it was called wan ( wide area network ) database query system, the databases are no more confined to web pages 更一般的,我們提出廣域網(wǎng)數(shù)據(jù)庫查詢系統(tǒng),廣域網(wǎng)數(shù)據(jù)庫查詢系統(tǒng)是架構(gòu)于各個專業(yè)數(shù)據(jù)庫系統(tǒng)之上的查詢系統(tǒng),各個專業(yè)數(shù)據(jù)庫系統(tǒng)存放的不再局限于網(wǎng)頁數(shù)據(jù)庫。
