The new era of web data warehousing: XML warehousing issues and challenges

Published:24 November 2008Publication History

ABSTRACT

The need to extract knowledge from web data warehousing just 'in-time' for decision making has increased significantly. An efficient system that can generate up-to-date analysis and decision making of the ever changing web-based information will play a very important role in the current global market and society. The new era of business intelligence and web databases brings in new research and development issues whereby the efficient integration of various web data is needed and timely analysis of data resources are vital. Web Data Warehousing is a growing area that addresses the need for an efficient web data summary to support decision making and ensure the quality of web data analysis.

It is a common knowledge that the majority of web information structure is now represented in an XML based representation. As a result, many domain standard bodies have also started to introduce the use of XML encoding for their data specification standard, such as BPEL (Business Process Execution Language) which is XML-based representation for business processes, HL7 (Health Language 7) which includes XML-based representation for health informatics data exchange, AIXM (Aeronautical Inter Exchange Model) in aeronautical data exchange, and so on. It is then crucial that a data warehouse be built with an underpinning technology that supports global information interactions and management and this is the reason for the emergence of XML representation for web data warehousing.

The hierarchical nature of XML within an XML data warehouse and the fact that it represents a document warehouse rather than the traditional table based relational warehouse, have raised the need for new methodologies in dealing with warehousing issues.

In this tutorial, we will cover specific issues in XML data warehousing, including:

• XML data warehouse design and construction

• Temporal XML data warehouse

• Right time XML data warehouse

• Security and Privacy in XML data warehouse

• Domain specific applications in XML warehousing: Health Informatics and Aviation (Air Traffic) Systems
