The goal of the workshops held along with ER 2002, the twenty first overseas convention on Conceptual Modeling, used to be to provide individuals the opportunitytopresentanddiscussemerginghottopics,thusaddingnewpersp- tives to conceptual modeling. to satisfy this aim, we chosen the next 4 workshops: – second InternationalWorkshop on Evolution and Changein info administration (ECDM 2002) – ER/IFIP8. 1 Workshop on Conceptual Modelling techniques to cellular - formation platforms improvement (MobIMod 2002) – overseas Workshop on Conceptual Modeling caliber (IWCMQ 2002) – third foreign Joint Workshop on Conceptual Modeling techniques for E-business: an online carrier point of view (eCOMO 2002) ER 2002 was once prepared in order that there will be no overlap among the c- ference periods and the workshops. This lawsuits comprises workshop papers that wererevisedby the authors following discussions throughout the convention. we're deeply indebted to the contributors of the organizing committees and application committees of those workshops for his or her exertions.

Sample text

The algorithm can reach a high matching accuracy, and has complexity O(n2 ) [33]. The additional step of computing the edit script is avoided when the publishing site communicates the changes directly to the web warehouse. Thus in the rest of the paper, we assume that the update log is given. Moreover, we will not go into details about the particular form in which the corresponding updates to the XML document are represented. While somewhat different representations have been used in the past, these differences are not significant in our study, and they are bound to disappear once a standard XML update language will emerge [30].

The historical representations and queries discussed here find applications in data warehouses that archive and collect data from sites of interest to assure the Preserving and Querying Histories of XML-Published Relational Databases 37 e-permanence [1] of critical information and support complex queries on changes [25]. Efficient support for archiving warehouse data is already supported in some commercial systems, and various techniques have been proposed for supporting complex queries on such historical data warehouses [34,27].
