An xml database management system ( dbms ) , designed for scalability , perfomance and open standards compliance 這是個(gè)xml數(shù)據(jù)管理系統(tǒng)( dbms ) ,具有可擴(kuò)展性、性能和支持開放標(biāo)準(zhǔn)等特點(diǎn)。
To efficiently use the ests data , a relationship database is constructed to store and organize them . the database management system ( dbms ) is ms sql server from microsoft 為了有效的管理這些數(shù)據(jù)和分析結(jié)果,使用微軟的數(shù)據(jù)庫管理系統(tǒng)mssqlserver建立了關(guān)系數(shù)據(jù)庫來存儲(chǔ)和組織這些信息。
Because data streams are continuous , unbounded , rapid and time - varying , traditional database management systems ( dbms ) is not very suitable in processing this kind of data 由于數(shù)據(jù)流的處理與傳統(tǒng)的靜態(tài)數(shù)據(jù)的處理有著巨大的差異,傳統(tǒng)的數(shù)據(jù)庫管理系統(tǒng)( dbms )已經(jīng)不能適應(yīng)對高速、時(shí)變的數(shù)據(jù)流處理的需求。
Because the failure of resolving the problem based on the solo traditional database management system ( dbms ) , an advanced solution based on the latest geographic information system ( gis ) is called up 如何有效的存儲(chǔ)、管理、交流,進(jìn)而充分利用這些災(zāi)害資料,僅僅運(yùn)用常規(guī)的數(shù)據(jù)庫管理系統(tǒng)已經(jīng)無法進(jìn)行有效地處理。
Query optimization is an important technique for designing and implementing database management system ( dbms ) . it is a crucial factor that affects the capability of database . at present , this technique is successfully applied in all commercial databases 查詢優(yōu)化是數(shù)據(jù)庫管理系統(tǒng)設(shè)計(jì)和實(shí)現(xiàn)所采用的一項(xiàng)重要技術(shù),它是影響數(shù)據(jù)庫性能的關(guān)鍵因素,當(dāng)前所有商用數(shù)據(jù)庫都成功采用了這項(xiàng)技術(shù)。
Hi the environment of microsoft visual c + + 6 . 0 and database management system ( dbms ) sql servert . o , the chinese version of window98 operating system , a fault diagnosis system is developed by using data mining methods , hi which visible rules are produced finally , the system is tested by experiment data of a rotaiy machinery 在windows98開發(fā)平臺(tái)上,結(jié)合開發(fā)工具microsoftvisualc + + 6 . 0 , sqlserver數(shù)據(jù)庫管理系統(tǒng)。采用面向?qū)ο蟮某绦蛟O(shè)計(jì)思想和模塊化程序設(shè)計(jì)方法,對基于顯式規(guī)則的幾種數(shù)據(jù)挖掘方法進(jìn)行了軟件實(shí)現(xiàn),開發(fā)了基于故障診斷的挖掘系統(tǒng),該系統(tǒng)具有一定的實(shí)用價(jià)值。
Then a conclusion , that it is very necessary to construct mis based on database in order to advance enterprises ' s efficiency and ameliorate departments " management , was reached . keeping to the procedure of developing database application systems , underlying the development environment delphi 6 . 0 and relying on database management system ( dbms ) microsoft sql server 2000 , the system analysis and design on mis of nanjing logistics corporation were presented in detail 遵循數(shù)據(jù)庫應(yīng)用系統(tǒng)開發(fā)步驟,在開發(fā)環(huán)境delphi6 . 0基礎(chǔ)上,以微軟的數(shù)據(jù)庫管理系統(tǒng)sqlserver2000為依托,本文系統(tǒng)地介紹了南京物流公司管理信息系統(tǒng)的系統(tǒng)分析與設(shè)計(jì),并對該系統(tǒng)的關(guān)鍵技術(shù)作了分析,提出了有效的解決方案。
With the constant extension in applications of computer , the object - oriented and active performance is more notable , and the traditional database management system ( dbms ) already can " t meet the needs of many modern applications . to meet the needs , an active and object - oriented database management system ( aoodbms ) is designed in this thesis . several aspects are introduced as follows 隨著計(jì)算機(jī)在應(yīng)用中的不斷擴(kuò)展,在面向?qū)ο蠛椭鲃?dòng)性方面的要求也越來越多,傳統(tǒng)的數(shù)據(jù)庫系統(tǒng)已經(jīng)無法滿足現(xiàn)代的許多應(yīng)用的需要,本文設(shè)計(jì)了一個(gè)主動(dòng)面向?qū)ο髷?shù)據(jù)庫系統(tǒng)以滿足這種需要,主要從以下幾個(gè)方面進(jìn)行了介紹:首先,本文分析了課題研究的背景、研究意義、研究歷史和研究現(xiàn)狀。
