In the past 30 years , the database system has already developed the no relational model , the next generation object - relational database system ( ordbs ) , the third generation object oriented database system ( oodbs ) . in the 1990s later , for the speed of the internet technique , the website base based on the internet promoted the information resource share 經(jīng)過30年的發(fā)展,數(shù)據(jù)庫系統(tǒng)已經(jīng)歷了第一非關(guān)系型數(shù)據(jù)庫、第二代關(guān)系型數(shù)據(jù)庫( ordbs )的發(fā)展到面向?qū)ο髷?shù)據(jù)庫系統(tǒng)( oodbs )和各種專業(yè)數(shù)據(jù)庫。九十年代后由于互聯(lián)網(wǎng)絡(luò)技術(shù)的飛速發(fā)展,基于互聯(lián)網(wǎng)的網(wǎng)站數(shù)據(jù)庫技術(shù)為信息資源的共享提供了技術(shù)上的保障。
In object system of special applied area , object is comparatively more stable than method , we can combine the object oriented frame with the method permanent management , hence at this means realize the permanent management of the object oriented system . this is a perfect application of the theory of the object oriented database system 在專門應(yīng)用領(lǐng)域的面向?qū)ο笙到y(tǒng)中,面向?qū)ο髴?yīng)用框架相對應(yīng)用對象方法表現(xiàn)的較為穩(wěn)定,將面向?qū)ο蟮膽?yīng)用構(gòu)架和面向?qū)ο蠓椒ǖ某志霉芾斫Y(jié)合起來并作為一個整體出現(xiàn),在這個角度上實現(xiàn)面向?qū)ο笙到y(tǒng)的持久化管理,是面向?qū)ο髷?shù)據(jù)庫系統(tǒng)應(yīng)用研究的一個良好案例。
And the designing principle , developing process and realizing concretely of water resource database management system are described in detail in this paper . jining water resources database management system ( jnwrdbms ) is established with advanced computer language and the technique of the database management techniques and using object oriented database management software - access 2002 and in - line vba 采用計算機語言和數(shù)據(jù)庫管理技術(shù),利用面向?qū)ο蟮臄?shù)據(jù)庫管理軟件access2002和內(nèi)嵌的vba ( visualbasicapplication )應(yīng)用程序語言,開發(fā)建立濟寧市水資源數(shù)據(jù)庫管理系統(tǒng)。
