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 在专门应用领域的面向对象系统中，面向对象应用框架相对应用对象方法表现的较为稳定，将面向对象的应用构架和面向对象方法的持久管理结合起来并作为一个整体出现，在这个角度上实现面向对象系统的持久化管理，是面向对象数据库系统应用研究的一个良好案例。
This paper has deeply research database designing and management information system using the object - oriented technology , and the main achievements acquired are as following : ( 1 ) has compared a few current popular object - oriented methods ; and pointed their advantages and disadvantages . ( 2 ) give out the methods to design the object - oriented database interface , and give out the algorithm that the pattern of object - oriented pattern to the relationship transforms ( 3 ) introduce the orient - relationship technique of the oracle9i database ( 4 ) finally , this text starts from developing an electric power marketing database system ; in this mis software develop of the application made the beneficial trial with the got 本文利用面向对象的方法对数据库设计与管理信息系统作了深入研究，取得的主要成果有： ( 1 )对时下几种流行的面向对象的方法进行了比较，论述其优缺点； ( 2 )给出了面向对象数据库接口设计方法的，并给出了对象模型向关系模型转化的算法( 3 )介绍了现在主流数据库oracle9i的对象关系技术( 4 )最后，从开发一个电力营销数据库系统入手，对oot在mis软件开发中的应用作了有益的尝试。
The oo analysis and design which are weak points in oo theory have also been analyzed and discussed . moreover , i have solved many difficult problems of oot in database system of the project . also , further exploration and beneficial test in how to convert traditional related database to oo database has been done in this paper 在课题的建设过程中，作者解决了一些面向对象技术在开发数据库管理系统中的疑难问题，在如何将传统的关系型数据库转换为面向对象数据库方面做了较为深入的探索和有益的尝试。
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 随着计算机在应用中的不断扩展，在面向对象和主动性方面的要求也越来越多，传统的数据库系统已经无法满足现代的许多应用的需要，本文设计了一个主动面向对象数据库系统以满足这种需要，主要从以下几个方面进行了介绍：首先，本文分析了课题研究的背景、研究意义、研究历史和研究现状。
It can be said that it improves the veracity of rule termination analysis . also , the similarity between aoodbms and workflow is considered , aoodbms is applied to the workflow detection . one mapping method from the workflow to the aoodbms is given , and some examples are given to introduce it 该方法考虑到了复合事件、条件等的影响，突破了已有方法的一些限制，对规则集的静态终止性分析判断的精确度有所提高；充分考虑到工作流程管理和主动面向对象数据库系统的相似性，将主动面向对象数据库系统应用于工作流程的监测，给出了由面向对象数据库系统来监测工作流程的对应方式，并举例进行了说明。
