Based on xml - based information intergration systems , this paper maily proposes how to construct the wrapper between object - oriented database and xml automaticly and fastly 本文提出采用xml与面向对象数据库转换技术，进行面向对象数据库包装器的构建与设计。
At last the fragment and replication of data are analyzed briefly in the process of transformation between c / s database and distributed database 并从数据库设计的角度，对客户/服务器结构下集中式数据库到分布式数据库转换的分解、复制，结合本系统数据库作了简要的分析。
This paper use the model driving method to design and implement the transaction middleware between xml and relational database called xrdbm ( xml - relational database middleware ) 本文以模型驱动映射思想为基础，设计并实现了xml与关系数据库转换的中间件xrdbm ( xml - relationaldatabasemiddleware ) 。
Practisingly it fulfills the exchange between the optical equipment database and xml . on one side , from the database to xml it can realize data issuance . on the other side , from xml to the database it can realize data integration 具体操作上，完成了光学设备数据库与xml的互相转换，一方面，数据库转换为xml模式，实现数据网上发布，另一方面， xml模式转换为数据库，实现数据集成。
After analyzed and compared characteristic of several common interface programs of database , mfc odbc interface of accessing database being abundant functions and operating easily , the thesis studies thoroughly the mechanism that mfc odbc is used to visit database . considering diversity of data formats in dems , file and source database transforming target database are sloved by mfc odbc 论文详细分析与比较了几种常用数据库接口编程，考虑到mfcodbc数据库接口功能丰富，操作相对简便，深入分析mfcodbc访问数据库机理，针对分布式试验与测试系统数据格式的多样性，利用mfcodbc开发并实现了文件数据及odbc源数据库转换到目标数据库过程。
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。
The system adoptes three - ply structure model , regards well expansibility . according the method of module . all system is composed of six module : courseware management , page studing , teaching discussion , guestbook , home work system and net - examination . the development based on asp which has the specialities of orient object and easy expansibility and microsoft access , finally . we reset the access to sql server when we shall issue it 系统采用三层体系结构，注重良好的可扩展性，采用模块化设计方法，将其划分为课件管理、页面学习、教学讨论、留言板、作业系统和网上考试六个功能模块，选择面向对象的、易于扩展的asp编程语言环境及access数据库系统开发实现，最后将access数据库转换为sqlserver数据库发布。
Analyze the systematic structure of the product data management system and study the object representation of the product data integration model , the product data attribute and operation , the product information modeling and the theory and method of access control modeling in order to set up the object model of the product data access control and describe the data base conversion of the object model and executive method 分析产品数据管理系统的体系结构，研究产品数据的集成模型的对象表示，产品数据属性和操作，产品信息建模和访问控制建模的理论和方法；建立产品数据访问控制的对象模型，并说明对象模型的数据库转换和实现方法。
The hsqldb approach was workable , but it quickly became clear that i would have to pay the object - relational impedance mismatch penalty not once , but twice - once when converting the tree - structured database into a relational data model , and again when trying to turn the results of flat relational queries into structured xml or html result sets Hsqldb方法是一个可行方法，但您很快就发现，我必须为对象关系的不匹配而两次（而不是一次）受罚一次是在将树型结构数据库转换为关系数据模型时，一次是在将平面关系查询结果转换成结构化的xml或者html结果集时。
