....or even resolved. There are various approaches how to deal with heterogeneous data sources. Some are more tightly coupled and define common views on multiple data sources, whereas more loosely coupled approaches maintain the autonomy of different distributes databases [Sheth J. Larson, 1990; Bouguettaya, Benatallah, Elmagarmid, 1998] 2 Preliminaries 2 A recent development is the creation of meta data repositories to manage meta data about systems, databases and the data therein [Marco, 2000] Meta data repositories play the role of information brokers and provide applications and users with the information necessary to ....

.... These types of judgments are typically intuitive, subjective, and part of the everyday life such that they usually display no strict mathematical models [1] In information systems similarity assessment is part of several processes, such as information retrieval [2 4] and data integration [5, 6]. Similarity assessment is particularly important for applications in which no precise definitions underlie the matter of discourse. In such domains, data stored in a database represent particular views of reality and users queries express only an approximation of what users want to retrieve, ....

....building. The methodology is supported by the DB MAIN CASE tool that helps generate the wrapper. 1 Introduction The most popular way to solve the heterogeneity problem of distributed legacy databases consists in wrapping them as objects that can be queried for retrieval and updating (e.g. 11] [2]) In this way, they can be given a standard interface, such as ODBC, JDBC or CORBA IDL, that allows system builders to federate old databases with newly developed ones in a uniform way [2] The problem of developing these wrappers is manifold. For instance, one has to solve the following ....

The problem of developing these wrappers is manifold. For instance, one has to solve the following questions: how to extract the conceptual schema of an existing, and generally undocumented, physical database, how to map this conceptual schema onto the physical data structures and how to ....

....outside the company or as a common information space for business partners and customers. The life cycle of an extranet can be either project specific or a more permanent solution. Some design methodologies that can be applied on intranet and extranet design have been reported in the literature (Bouguettaya, Benatallah and Elmagarmid, 1998; Garzotto, Paolini and Schwabe, 1993; Isakowitz, Stohr and Balasubramanian, 1995; Lee, 1998) Extranets provide inter organizational information spaces where business partners and customers can work together, develop common and systematic working procedures, and share information as well as ....

....database friendly. This essentially means that we need to build an adequate infrastructure on top of the Web that will provide for a World Wide Database (WWD) In order to address problems of scalability and language support for Web accessible databases, the WebFINDIT prototype has been developed [3, 1]. WebFINDIT is a system for describing, locating and accessing data in Internet accessible databases. We present an architecture and supporting tools that enable users to build complex and emerging Web applications in a simple and flexible way. The main idea is to incorporate simple access to ....

....into a flexible interoperable architecture for large information spaces. Most existing techniques focused extensively on either data sharing among small number of heterogeneous databases or on information discovery and brokering in the context of unstructured or semistructured Web resident data [1]. In our research, we consider issues to achieve the database equivalent of the WWW. We call it the World Wide Database (WWD) The WWD will be fundamentally different from the WWW in that databases are relatively closed as compared to traditional Web resident data. Therefore, we need to devise an ....

....the Internet and the Web increased dramatically the need for data sharing. The Web has brought a wave of new users and service providers to the Internet. It contains a huge quantity of heterogeneous information and services (e.g. home pages, online digital libraries, product catalogs, and so on) (Bouguettaya et al. 1998). The result is that the Web is now accepted as the de facto support in all domains of life activities: finance, education, travel, business, science, healthcare, art, etc. The data provided in the Web is not only semi structured (e.g. HTML documents, mail messages) or unstructured (e.g. text ....

....These solutions usually rely on centralized database administrators to document database semantics or to develop translators that hide differences in query languages and database structures. Tightly coupled approaches offer better solutions for the heterogeneity problem by using a global schema (Bouguettaya et al. 1998). However, this scheme does not provide site autonomy nor does it scale up given the complexity when constructing the global schema for a large number of heterogeneous systems. The MIND project investigated the use of CORBA to implement a tightly coupled interoperability approach (Ozcan et al. ....
