One Implementation of Central Catalogue for Local Library Record Databases

Abstract

record database. These library information systems can form library network that could incorporate all local library record databases. In this case, it would be necessary to implement virtual central catalogue for the library records in order to enable search over those incorporated databases. One implementation of the central catalogue could be done using the distributed components technology. Consequently, library record database search could be performed by the specialized distributed software components – software agents. For each library server there is one software agent that is capable of searching in the database. Query issued to the central catalogue is distributed to all agents, and then all of them execute that query simultaneously. All query results are incorporated into one joint result that is presented in the central catalogue.
