Existing mib of cadres in the army was established on the basis of traditional technique of database 現(xiàn)有的軍隊(duì)干部管理系統(tǒng)是基于傳統(tǒng)的數(shù)據(jù)庫技術(shù)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(shù)據(jù)庫是決策支持技術(shù)的關(guān)鍵,數(shù)據(jù)庫技術(shù)的成熟也是數(shù)據(jù)倉庫技術(shù)提出的基礎(chǔ),而數(shù)據(jù)倉庫和數(shù)據(jù)挖掘技術(shù)是決策支持新技術(shù),它將成為一體化信息支持系統(tǒng)的核心技術(shù)。
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(rèn)真研究了市場營銷中連鎖銷售經(jīng)營模式后,提出了基于數(shù)據(jù)庫技術(shù)的數(shù)據(jù)倉庫、聯(lián)機(jī)分析處理、數(shù)據(jù)挖掘三種技術(shù)相結(jié)合的連鎖銷售決策支持系統(tǒng)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(chǔ)上,本文開發(fā)了港口拖輪配置的仿真系統(tǒng)軟件,在軟件設(shè)計(jì)時(shí),采用了數(shù)據(jù)庫的技術(shù)來存儲(chǔ)仿真運(yùn)行時(shí)產(chǎn)生的大量數(shù)據(jù),方便用戶對(duì)仿真數(shù)據(jù)進(jìn)行維護(hù)。
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(duì)數(shù)字?jǐn)z影測量和計(jì)算機(jī)技術(shù)的飛速發(fā)展,分析了目前測繪部隊(duì)生產(chǎn)中存在的問題和當(dāng)前對(duì)數(shù)字?jǐn)z影測量系統(tǒng)的要求,深入的研究了數(shù)字?jǐn)z影測量的基本理論和數(shù)據(jù)庫、 webgis 、 web3d等空間信息共享平臺(tái)的關(guān)鍵技術(shù),完成了一套數(shù)字?jǐn)z影測量從數(shù)據(jù)獲取和管理到應(yīng)用的集成系統(tǒng)。
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(tǒng)的數(shù)據(jù)庫技術(shù)以單一的數(shù)據(jù)資源,即數(shù)據(jù)庫為中心,進(jìn)行從事務(wù)處理、批處理到?jīng)Q策分析等各種類型的數(shù)據(jù)處理工作,盡管數(shù)據(jù)庫在事務(wù)處理方面的應(yīng)用獲得了大的成功,但它對(duì)分析處理的支持一直不能令人滿意,尤其是當(dāng)以業(yè)務(wù)處理為主的聯(lián)機(jī)事務(wù)處理( oltp )應(yīng)用與以分析處理為主的決策支持系統(tǒng)( dss )應(yīng)用共存于同一個(gè)數(shù)據(jù)庫系統(tǒng)時(shí),兩種類型的處理發(fā)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(gòu)件的使用性能,在其內(nèi)部使用了數(shù)據(jù)庫連接池技術(shù),在各種查詢返回?cái)?shù)據(jù)集的處理上,使用了java對(duì)象序列化技術(shù);另一方面,針對(duì)非java語言客戶端,同時(shí)提供了一種一般化的數(shù)據(jù)集處理方式,該方式的效率較前者稍低。
