    • 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.
    • 本发明提供了一种使用彼此具有不同数据结构的多个数据库的技术。 在便携终端P上指定基于全局本体G的搜索条件的用户,该多个数据库共同的数据项的列表。 代理A从代理启动器L发送到连接节点S.在连接节点S中,提供了用作表或包含关于全局本体G与每个数据库之间的对应关系的信息的字典的数据。 基于全局本体G的搜索条件基于数据被转换为与每个数据库的结构兼容的格式。 具有翻译搜索条件的代理A移动到每个数据库所在的节点,传送在每个节点获得的搜索结果,然后返回到连接节点S.
