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(kù)查詢?cè)O(shè)計(jì)
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(kāi)發(fā)的農(nóng)業(yè)水土工程信息數(shù)據(jù)庫(kù),數(shù)據(jù)查詢操作簡(jiǎn)單,具有很好的動(dòng)態(tài)交互性、及時(shí)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(kù)查詢系統(tǒng)中應(yīng)用自然語(yǔ)言理解技術(shù),設(shè)計(jì)數(shù)據(jù)庫(kù)自然語(yǔ)言查詢接口,已成為自然語(yǔ)言研究中最具有廣泛應(yīng)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(kù)查詢系統(tǒng),廣域網(wǎng)數(shù)據(jù)庫(kù)查詢系統(tǒng)是架構(gòu)于各個(gè)專業(yè)數(shù)據(jù)庫(kù)系統(tǒng)之上的查詢系統(tǒng),各個(gè)專業(yè)數(shù)據(jù)庫(kù)系統(tǒng)存放的不再局限于網(wǎng)頁(yè)數(shù)據(jù)庫(kù)。
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(wǎng)數(shù)據(jù)庫(kù)查詢系統(tǒng)提供用戶關(guān)于某一類數(shù)據(jù)庫(kù)信息的統(tǒng)一的查詢界面,它調(diào)用各個(gè)獨(dú)立網(wǎng)站數(shù)據(jù)庫(kù)系統(tǒng)對(duì)用戶輸入的查詢條件進(jìn)行實(shí)時(shí)并發(fā)查詢,同時(shí)合并查詢結(jié)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(wǎng)站的網(wǎng)絡(luò)服務(wù)器平臺(tái)用widnows2000server搭建,網(wǎng)頁(yè)用frontpage2000 、 dreamweaver4制作,網(wǎng)絡(luò)系統(tǒng)的動(dòng)態(tài)數(shù)據(jù)庫(kù)查詢系統(tǒng)用dhn4l 、 asp 、 visualinterdev 、 sqlserver2000完成,并開(kāi)發(fā)編寫(xiě)了服務(wù)器端軟件。
