Page server is adopted in KDOODB, which is a reasonable architecture, and KDOODB is an open system. Based on the ODMG-93 standard, the programming language C++ is expanded to act as programming language for database application, the impedance mismatch had been avoided, and the seamless integration of programming language and OODBMS had been realized. In KDOODB, big objects and complicate objects can be accessed quickly; the flexible deprocedure query language is provided, it can be used as both the embedded programming language and interactive command; WAL_P and the bit-based transaction identifier assignment strategy provide powerful support for the transaction management; several use patterns and friendly user interface are provided.

KDOODB系统采用了合理有效的页服务器结构，具有良好的开放性；基本符合ODMG-93国际标准，扩充当前国际上流行的面向对象编程语言C＋＋作为数据库应用编程语言，实现了数据库编程语言与OODBMS 的无缝集成，有效地避免了"阻抗失配"问题；能够快速存取大对象和复杂对象；提供方便灵活的非过程化的查询语言，既可以嵌入编程语言使用，又可以作为交互式命令使用；基于页的恢复策略和基于位的事务标识分配策略为有效的事务管理提供有力支持；为用户提供多种使用方式和友好的用户界面。

This paper introduces the background knowledge of heterogeneous data integration, as well as the knowledge of data integration. On the basis of the above, The author develops an ontology-based Heterogeneous data Integration prototype system, expounds the main framework and essiontial technology. Then the paper introduces its work in detail: it explains the very significance of using ontology as an comon semantic description and an global query model ,and illustrates the reason fo adopting LAV method ; then it builds the formal representation of the mapping between ontology and data resources, applies OWL to describe the ontology and the mapping ; defines a query language named by DIQL to query on our integration system , and supply the detailed arithmetic of reolving partial binding of LAV method、locating of data sources and query rewriting,etc. Finally,the paper demostrates and proves the result of research by examples .

本文介绍了目前异构数据集成的研究现状以及数据集成和本体的相关背景知识，并在此基础上设计开发了一个基于本体的异构数据LAV集成原型系统，同时对原型系统的总体框架、关键实现技术分别做了讨论：首先阐述了将本体作为公共语义描述和全局查询模型的意义，给出了采用LAV集成方案的理由，然后规定了本体和数据源间映射的形式化表示方式，采用能结合描述逻辑和框架系统的优点、适合于半结构化环境的OWL表示本体和映射；其次定义了一种针对集成系统的查询语言DIQL，并在此基础上给出解决LAV部分绑定问题、数据源定位以及查询重写的算法；最后在原型系统的基础上，通过实例验证本文所提方法的可行性。
