....of the above query languages lack ECA rules. Web query languages, such as W3QL [13] view the Web as a single huge database and enable to address the structures and contents. XBML views a single Web source as a database and allows queries over Web based distributed databases. The active views [1] focuse on the comprehensive functionality of ECA rules. On the other hand, we have concluded the necessity of ECA rules from the experiences of applying XBML to concrete businesses. We extend the query optimization in relational databases[14] to the distributed context. ....

....and swap operation. Finally, we develop a comprehensive algorithm that checks for the validity of XML views constructed by applying the four operations. 1 Introduction It is necessary to provide for XML views [1] Several systems have been proposed to support XML views, including Active Views [2] and MIX [5] While both systems provide for the definition of XML views, they do not validate the views that are created. Therefore, there is no guarantee that the views defined are valid. In this paper, we propose a systematic approach to ensure the validity of XML views. First, we transform ....

....views can be defined on top of the default view. In addition, XQuery [17] is adopted to issue query on views of relational data in [15] Xyleme [10] defines an XML view by connecting one abstract DTD to a large collection of concrete DTDs with an extension of OQL as the query language. ActiveView [2] [3] defines views with active features, such as method calls and triggers, on ArdentSoftware s XML repository using a view specification language. In addition, XML views are also supported as a middleware in integration systems, such as MIX [4] YAT [9] and Agora [21] 2 All these systems ....

....Distributed Active Systems (ODAS) comprised of independent event and rule managers. These systems can be used to support transparent integration, cooperation of distributed database and non database reactive components at a middleware level. For example to support electronic commerce applications [1], to manage business rules used for changing statically and dynamically views of Web sites [6] In such contexts, rules can be processed with event managers at the client level and rule managers at the Web server level. 1.2 Related Work Existing works for offering active functionalities as open ....

....and Database fields, the modelling of AHs requires to consider the different sources that affect the adaptation process. The approach that seems to be the most promising for modelling the Application domain is data centric, and many researches employ well known database modelling techniques [1]. The adaptation of the presentation to the User Model can be generally distinguished into adaptive presentation, i.e. a manipulation of information fragments, and adaptive navigation support, i.e. a manipulation of the links presented to the user [5] Due to the complexity of user models that ....

....DBMS made out of components would indeed be an actual component based solution of a database system. We motivate this further in the following section. 3.2.2 Component vs. monolithic DBMS Database systems are today used in various application areas, such as telecommunications [1] e commerce [37, 2], embedded systems [80] real time systems [44] etc. Expansion of database systems to new application domains unavoidably results in new requirements a database system must fulfill [29] Consider Internet applications where data is accessed from a variety of sources such as audio, video, text, ....

Aviv 1 Overview The goal of this demonstration is to present the ma n features of (i) Axielle, an XML repository developed by Ardent Software [3] on top of the O= object oriented DBMS and (ii) the ActiveView system which has been built by the Verso project at INRIA [1] on top of Ax ielle. The demonstration is based on a simple electronic commerce application which will be described in Section 2. Electronic commerce is emerging as a major Web supported application. It involves handling and exchange of data (e.g. product catalogs, yellow pages, etc. and must ....

On the other hand, the view and the interface see the same data. 2. 3 Specification Language and Application Generator The above application can be specified in the high level ActiveView Language (AVL) [1] we have defined for describing electronic commerce applications. Acting as an application generator, the Active View system can then generate an actual application that captures the semantics of the above specification and allows the different users to work interactively on the specified data for ....
