Abstract: XML - the Extensible Markup Language has recently emerged as a standard for information representation and exchange on the internet, because of its portability, versatility and extensibility. As the large increase in the availability of such data, there is a need of an appropriate storage and an integration solution for future analysis and decision-making. Data warehouses systems provide a suitable means to organise and manage XML data for decision-making. However, XML data warehouse has some special requirements such as mixed content and irregular structure of XML data sources, which make existing traditional data warehouse approaches and techniques unsuitable. In this paper, we give an overview of current state of the art concerning how XML technologies can be combined with data warehousing systems, by the presentation of the most relevant XML warehousing approaches proposed in the literature.
Keywords: XML data warehouses; data warehouse design; web data; dimensional modelling; XML warehousing.
