The aim is pruning efficiently out information sources that are unsuitable for a given query and generating executable query plans. In the Global Schema Builder layer are grouped the agents that support the integration process. Proxy agents are information collectors. They acquire the local schemata created by the TAs. This knowledge base will be manipulated and enriched during the integration activities by the other Global Schema Builder layer agents and maintained in the corresponding Proxy agents.
Notice that a common feature of the agents belonging to the Global Schema Builder layer is the interaction with the MIKS system tools. These are either knowledge bases (as the WordNet data base) or already existing applications (as ARTEMIS and ODB-Tools) developed in other research projects. All of the tools have sufficiently sophisticated interfaces to allow interaction with other applications. Thus, it is easy to make them interoperate with agents. This can be done by agentifying these applications (agents that are expressively being designed for exchanging data and calling functions of the tool) or by exposing the functionalities of the tools as web services.
A possible interaction pattern for the query solving phase information sources giving the illusion of a centralized, homogeneous information system. It is based on a global schema, completely modelled by the user, and a core system that dynamically determines an efficient plan to answer the user’s queries by using translation rules to harmonize possible heterogeneities across the sources. t. our approach is the lack of a tool aid-support for the designer in the integration process. As for the multi-agent system community, some work has been done in the direction of integration systems.
