....integrated approaches, local databases are integrated into a single distributed database (DDB) A distributed DBMS (DDBMS) is built to manage the DDB. Most of these approaches are monolingual: the DDBMS supports a single data manipulation language, which has to be used to query and update the DDB ([16, 44], for instance) Any existing program on a local database has to be rewritten using the distributed DDL DML. To avoid this burden, some authors advocated that integrated systems should be multilingual, i.e. should offer at each participating site the ability to access the DDB through the ....

....new applications exist in both cases. One approach to dealing with this problem has been the heterogeneous distributed database system (HDDBMS) A HDDBMS is a set of components designed to integrate existing DBMSs and their associated databases. Much work has been done on this subject (see, e.g. [DEEN87, JAKO86, LAND82, LITW86, STOC84, TEMP86]) and it remains a very active area of research. The general approach taken by many of these systems is illustrated by the generic component architecture shown in Figure 2.3.1. 12 . Global Query Language .

....participating databases. These assumptions are legitimate because the number of databases considered is always small. They are also legitimate because the underlying architecture assumed, is either based on schema integration(Batini, 1986) Templeton, 1986) Landers, 1982) Smith, 1981) Litwin, 1982)(Stocker, 1984)(Kim, 1991) Motro, 1981) or federated databases (Heimbigner, 1985) Sheth, 1990) In a large network of databases, the above assumptions cannot be met. The paper is divided as follows. In Section 2, we present an overview of FINDIT framework that includes new concepts needed to address the new ....
