Information-Integration in the Context of XML and Object-Relational DBMS (IXOR)

在这个研究项目中，我们希望集中在当前数据库研究的两个非常重要的方面：-使用XML和对象关系技术的信息集成-DBMS处理能力适应客户/服务器环境。这些研究课题变得越来越重要，主要是因为以下两个原因。首先，由于新的SQL标准(特别是SQL：1999中面向对象的增强)，在所谓的对象关系型数据库管理系统中越来越需要将XML(XSQL)、关系技术和面向对象技术结合在一起。其次，任何面向对象和关系技术的合并都必须考虑到客户端和服务器处理能力的合并。后一点的原因是，面向对象的DBMS是专门为客户端/服务器环境设计的，设计重点放在客户端，而大多数关系DBMS是在设计时考虑到服务器DBMS的。

In this research project we want to concentrate on two very important aspects of current database research:-Information Integration using XML and object-relational technology-Adaptation of DBMS processing capabilities to client/server environments.These research topics are getting more important, mainly because of the following two reasons. First, due to the new SQL-standard (especially the object-oriented enhancements in SQL: 1999 there is a growing need to combine XML (XSQL), relational technology and object-oriented technology within so-called object-relational DBMS. Second, any merge of object-oriented and relational technology has to take also a merge of client and server processing capabilities into consideration. The reason for the latter point is that object-oriented DBMS have been designed especially for client/server environments with much design emphasis put on the client part, whilst most relational DBMS were devised having a server DBMS in mind.
