....in many cases, source code for popular free software can be updated using the patch [29] program, with servers providing differences between the original version and the new version. For web sites, differences in terms of structural changes in the links, can be encoded using tables as in WHOWEDA [5]. Serve pages only if modified. The web crawler can avoid downloading a file if it has not been modified. This is done using a date that the crawler provides usually the last visit to the same page in HTTP 1.0. A more precise alternative is to provide an entity tag (E Tag) a fingerprint ....

....are a variety of interesting design proposals for web database systems, such as W3QS [Konopnicki M. Ramanath and J. Haritsa, DIASPORA:A Distributed Web Query Processing System 25 and Shmueli 1995] WebSQL [Mendelzon et al. 1997] WebLog [Lakshmanan et al. 1996] WHOWEDA [Bhowmick et al. 1998; Bhowmick et al. 2000], Araneus [Atzeni et al. 1997] WebOQL [Arocena and Mendelzon 1998] etc. for lack of space we review below the salient features of only two systems WHOWEDA and WebOQL. For a more comprehensive overview on the integration of web and database technology, please refer to [Florescu et al. 1998] ....

....and multidimensional structures have to be built for all relations. Moreover, the results are not directly applicable for largescale applications, such as e.g. OLAP. In addition, web technology can benefit from universal quantification as expressed for example in the web join approach like in [3]. In the following, in order to assess the applicability of the different implementation approaches, namely hash join, anti semijoin and StreamJoin, we will consider two example scenarios employing universal quantification. 3.2. Example Scenario 1: The University Database We first consider the ....
