ABSTRACT:
This invention provides a technology for using a plurality of databases each having dissimilar data structure with each other. A user specified, on a portable terminal P, a search condition based on a global ontology G, a list of data items common to the plurality of databases. An agent A is sent from an agent launcher L to a connection node S. In the connection node S, data used as a table or a dictionary containing information on a correspondence between the global ontology G and each of the databases is provided. A search condition based on the global ontology G is translated based on the data to a format compatible with the structure of each database. The agent A, with the translated search condition, moves to a node where each database is located, transfers the search result obtained at each node, and then returns to the connection node S.
