Techniques of database connection pool and javabean implementation 數據庫連接池的分析與實現
The vb - based accession technique of database 的數據庫訪問技術
Existing mib of cadres in the army was established on the basis of traditional technique of database 現有的軍隊干部管理系統是基于傳統的數據庫技術建立的。
Mature techniques of database is also foundation of dw ( data warehouse ) techniques that bring up , but it is decision that dw and dm ( data mining ) to support the new techniques , it will become core techniques of the integral information support system 數據庫是決策支持技術的關鍵,數據庫技術的成熟也是數據倉庫技術提出的基礎,而數據倉庫和數據挖掘技術是決策支持新技術,它將成為一體化信息支持系統的核心技術。
Having studied the relative sale managing model in the marketing , this paper gives a new settlement for relative sale decision support system which is based on techniques of database based data warehouse , online analysis processing and data mining 然后,在認真研究了市場營銷中連鎖銷售經營模式后,提出了基于數據庫技術的數據倉庫、聯機分析處理、數據挖掘三種技術相結合的連鎖銷售決策支持系統的新型解決方案,即dw + olap + dm dss的可行方案。
On the above theories foundation , this paper will program simulation software for the port ' s tugboat marshaling , at the moment of designing , for the consumer ' s convenience using , the software will save and maintenance the large data of simulation running by adopting the technique of database 在上述的基礎上,本文開發了港口拖輪配置的仿真系統軟件,在軟件設計時,采用了數據庫的技術來存儲仿真運行時產生的大量數據,方便用戶對仿真數據進行維護。
Aimimg at the rapid development of the digital photogrammetry and computer technique , this paper analyzes problems existing during production process in survey unit and the current demand on digital photogrammetry system , studies the basic theory of digital photogrammetry and the pivotal techniques of database > webgis , web3d and other network shared platform technologies , and accomplishes a integrated digital photogrammetric system including the whole process from data acquisition and managing to application 本文針對數字攝影測量和計算機技術的飛速發展,分析了目前測繪部隊生產中存在的問題和當前對數字攝影測量系統的要求,深入的研究了數字攝影測量的基本理論和數據庫、 webgis 、 web3d等空間信息共享平臺的關鍵技術,完成了一套數字攝影測量從數據獲取和管理到應用的集成系統。
Traditional technique of database was centered by single data resources ( database ) to all kinds of data management including dealing with affairs , batch and decision - analyses . although database made great success in the application of dealing with affairs , the support of analysis and management has been unsatisfactory , especially , when the application of oltp which mainly deal with affairs and the application of dds which mainly deal with analysis are in the same system of database , the two kinds of managements have an obvious conflict 傳統的數據庫技術以單一的數據資源,即數據庫為中心,進行從事務處理、批處理到決策分析等各種類型的數據處理工作,盡管數據庫在事務處理方面的應用獲得了大的成功,但它對分析處理的支持一直不能令人滿意,尤其是當以業務處理為主的聯機事務處理( oltp )應用與以分析處理為主的決策支持系統( dss )應用共存于同一個數據庫系統時,兩種類型的處理發生了明顯的沖突。
In order to improve the performance of the component , the technique of database connection pool is used internallv , and in the process of disposing the data muster , the java object sequentializing technique is used . on the other hand , a general method of disposing the data muster is presented to non - java language client . the efficiency of this method is lower than the foregoing 為了提高該構件的使用性能,在其內部使用了數據庫連接池技術,在各種查詢返回數據集的處理上,使用了java對象序列化技術;另一方面,針對非java語言客戶端,同時提供了一種一般化的數據集處理方式,該方式的效率較前者稍低。
