基于XML数据立方的面向对象扩展

Oriented-object for XML-based Data Cube

本文是对基于XML的数据立方数据模型的面向对象的实现.通过对数据仓库技术、面向对象技术和XML技术的结合的探讨,扩展了XML Schema,从而为基于WEB数据仓库的应用提供了一种新的表示和实现方法,解决了数据仓库中模式演化所带来的重组问题,通过与面向对象技术的结合使用,把数据仓库变成为数据立方和OLAP方法的仓库.这种数据仓库的实现方案,保证了数据仓库系统的稳定性、灵活性和可扩展性,适应了新一代WEB应用的需要.

This paper focuses on extending XML-based data cube with Oriented-object techniques. It presents how to take advantage of XML and Oriented-Object techniques in data warehouse environment. This method deals with such problems as more semi-structured data from applications and more operation between heterogeneous data sources and web. XML is a standard for information exchange and transmission on the web, and data warehouse is a good solution to provide an exclusive business environment to storage and management mass semi-structure data from web and other applications. This paper presents how to describe data cube with XML format and gives an example how to use orient-ed-object method for XML-based data cube in order to reuse OLAP operations and other functions.
