Based on the three layer architecture technology, the platform system is developed by microsoft visual studio. net, and it realizes the operating module on database based on component technique of ado. net interface ; sql server 2000 is as the database management system, defines some key tables of database, designs an realizes the functions of appending, querying and renewing services, such as the organization, personnel, production, project and information issue of the scientific research management, respectively in the research part of ispssrm ’ s development, it first analyzes inadequacies and technological difficulties of the original edition of ispssrm, then discusses the problem of dealing with diagonal line, the combination of multi - table, the design of query on dynamic tables, and the web report forms, and the extension of the service function such as the applying and estimating in web, and finally proposes the concept to extend the function of ispssrm
Net開發工具，基於三層結構技術實現了web業務功能模版;基於ado . net介面的組件方式實現了數據庫訪問操作，在數據存儲層使用sqlserver2000作為后臺數據庫管理系統，定義了數據庫關鍵表;設計實現了科研管理的機構、人員、成果、項目、信息發布、維護等業務的添加、查詢、更新功能。在ispssrm的發展研究部分，首先分析了ispssrm原型系統的不足之處及存在的技術難題，探討了動態表格的斜線處理、多表合併、查詢設計及web的列印問題以及網上申報、評審功能模塊等業務功能的拓展，提出了擴展ispssrm的功能的思路。 ispssrm現已經在蘇州大學科研處投入試運行，為高校的科研管理信息化建設、提高科研管理水平提供了一個切實可行的方案。 -
Query processing is one of the key techniques in information integration. the dissertation introduces query decomposing, query optimization, query scheduler, sub - query combination
在查詢處理的基本體系結構基礎之上，本文重點介紹了查詢分解、查詢優化、查詢調度以及子查詢合併。 -
A query tree can be got from the query decomposing rules, and a query graph can be generated by optimizing the query tree and applying the arithmetic of generating a query graph. at last, a query plan will be generated by using kruskal heuristic arithmetic two times on query scheduler and sub - query combination
通過查詢分解規則可得到查詢樹，對查詢樹進行分解優化並按照查詢圖生成演算法可得到一個查詢圖，然後兩次運用kruskal啟發式演算法對查詢調度和子查詢合併進行了優化，最後產生查詢計劃。 -
The paper explains how to enhance performances of asp program, realizing single - condition query, multi - condition combination query and directory tree navigating query. finally the paper gives technique point of the three query methods. 7
闡述了通過asp實現查詢及動態網頁的原理和過程，在此基礎上設計了單條件動態檢索、多條件組合檢索和目錄結構樹導航檢索多種檢索方案，並介紹了支持這些方案的技術要點。 -
Therefore, the task of the query optimizer is to select an index, or combination of indexes, only when it will improve performance, and to avoid indexed retrieval when it will hinder performance
因此，查詢優化器的任務是只在索引或索引組合能提高性能時才選擇它，而在索引檢索有礙性能時則避免使用它。 -
In a query, the combination of an expression or query subclause and its adjacent logical operator
查詢中，表達式（或查詢的子子句）與其相鄰邏輯運算符的組合。 -
Our system is supported by a strong background multimedia database and has several characteristic query methods. it integrates various of dynamic query technologies of the single - condition query, multi - condition combination query, directory tree navigating query, and with a individual material database for every user. background multimedia material database can self - expanded during interactive operating with web users time after time
