Design of heterogeneous distributed database query system based on layering thought 基于分層思想的異構分布式數據庫查詢設計
Querying the dynamic network database query system of this website is very easy , convenient , well timely and has good intercommunication 本網站所開發的農業水土工程信息數據庫,數據查詢操作簡單,具有很好的動態交互性、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 在數據庫查詢系統中應用自然語言理解技術,設計數據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,我們提出廣域網數據庫查詢系統,廣域網數據庫查詢系統是架構于各個專業數據庫系統之上的查詢系統,各個專業數據庫系統存放的不再局限于網頁數據庫。
It provides users a unique interface , accept the query terms , run and return the results like meta - search engine do . in this paper we have developed a wan search database query system for practice use , and this project is supported by national funds 廣域網數據庫查詢系統提供用戶關于某一類數據庫信息的統一的查詢界面,它調用各個獨立網站數據庫系統對用戶輸入的查詢條件進行實時并發查詢,同時合并查詢結果返回給用戶。
The network systemic platform is set up by the systemic software - windows 2000 server . webpages is made by using the application software : frontpage2000 and dreamweaver4 . the dynamic network database query system is founded by asp , dhtml , sql server 2000 網站的網絡服務器平臺用widnows2000server搭建,網頁用frontpage2000 、 dreamweaver4制作,網絡系統的動態數據庫查詢系統用dhn4l 、 asp 、 visualinterdev 、 sqlserver2000完成,并開發編寫了服務器端軟件。
