“…In this section, we describe the well-defined web integrated data warehouse model, which had been proposed in our previous work [10]. The challenge behind the integration of web data and non-web data is that data from different resources very often appear to be very inconsistent in their representation.…”

“…In the completion of the definition of the integrated data warehouse model for this case study, we follow our set of rules, proposed in our previous work [10] to map from the underlying data source structures to the integrated structure in our predefined integrated data warehouse model. The complete integrated data warehouse model is shown in Fig.…”

“…The question is how are these sources data going to be unified in order to produce quality information to support the decision making? Figure 4 is a well-defined web integrated data warehouse structure [10] that represents the case study problem. The complete integrated university logical data warehouse model fully utilizes the powerful object-oriented features where storing the hierarchy in a dimension table allows for the easiest browsing of subject, degree and faculty dimension data in a timely manner.…”

“…The well-defined web integrated data warehouse model had been proposed in our previous work [10] where we adopted an object-oriented design concept where the model itself successfully provided rich and powerful features that have the ability to fully represent the data semantics. Thus, our main contribution in this paper does not concern the integration technique; instead, we investigate the performance of our proposed structure based on our integration technique.…”

“…Web information extraction and selection are very tedious processes which may involve very complicated tasks that could result in a high cost. To avoid unnecessary overheads, we therefore evaluate the performance of such a system to ensure the efficiency of resources, consistency of integrated data, reliability of system operations, as well as significant benefits to support the business entities' commitment to an integrated web data warehouse application using our proposed integration technique for an integrated web data warehousing in [10]. Figure 1 shows an overview of an integrated web data warehouse structure that needs to be implemented so that evaluation can be carried out to support the efficiency of data retrieval and the overall significant benefits.…”

Over the years, we have seen a significant number of integration techniques for data warehouses to support web integrated data. However, the existing works focus extensively on the design concept. In this paper, we focus on the performance of a web database application such as an integrated web data warehousing using a well-defined and uniform structure to deal with web information sources including semi-structured data such as XML data, and documents such as HTML in a web data warehouse system. By using a case study, our implementation of the prototype is a web manipulation concept for both incoming sources and result outputs. Thus, the system not only can be operated through the web, it can also handle the integration of web data sources and structured data sources. Our main contribution is the performance evaluation of an integrated web data warehouse application which includes two tasks. Task one is to perform a verification of the correctness of integrated data based on the result set that is retrieved from the web integrated data warehouse system using complex and OLAP queries. The result set is checked against the result set that is retrieved from the existing independent data source systems. Task two is to measure the performance of OLAP or complex query by investigating source operation functions X.T. Dung ( ) · used by these queries to retrieve the data. The information of source operation functions used by each query is obtained using the TKPROF utility.

In the last few years we have observed a proliferation of approaches for clustering XML documents and schemas based on their structure and content. The presence of such a huge amount of approaches is due to the different applications requiring the clustering of XML data. These applications need data in the form of similar contents, tags, paths, structures, and semantics. In this article, we first outline the application contexts in which clustering is useful, then we survey approaches so far proposed relying on the abstract representation of data (instances or schema), on the identified similarity measure, and on the clustering algorithm. In this presentation, we aim to draw a taxonomy in which the current approaches can be classified and compared. We aim at introducing an integrated view that is useful when comparing XML data clustering approaches, when developing a new clustering algorithm, and when implementing an XML clustering component. Finally, the article moves into the description of future trends and research issues that still need to be faced.
