Abstract
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.

Claim 11
Dependent Claim
29 words
The data processing apparatus according to claim 8, wherein said data generated through activity represents at least one of the current status of each agent and said search result.
