  Web Warehouse is a read only repository maintained on the web to effectively
handle the relevant data. Web warehouse is a system comprised of various
subsystems and process. It supports the organizations in decision making.
Quality of data store in web warehouse can affect the quality of decision made.
For a valuable decision making it is required to consider the quality aspects
in designing and modelling of a web warehouse. Thus data quality is one of the
most important issues of the web warehousing system. Quality must be
incorporated at different stages of the web warehousing system development. It
is necessary to enhance existing data warehousing system to increase the data
quality. It results in the storage of high quality data in the repository and
efficient decision making. In this paper a Quality Evaluation Framework is
proposed keeping in view the quality dimensions associated with different
phases of a web warehouse. Further more, the proposed framework is validated
empirically with the help of quantitative analysis.
