An architecture for online information integration on concurrent resource access on a Z39.50 environment
MetadataShow full item record
The lack of information integration, by the existing online systems, for resource sharing in a distributed environment, impacts directly to the development and the usage of dynamically defined Virtual Union Catalogues. In this work we propose a design approach for the construction of an online system, able to improve the information integration when a Dynamic Resource Collection is used, by taking into account the restrictions imposed by the network environment and the 739.50 protocol. The main strength of this architecture is the presentation of de-duplicated results to the user, by the gradual application of the duplicate detection process in small received packets (sets of results), as the data packets flow from the participating servers. While it presents results to the user, it also processes a limited amount of data ahead of time, to be ready before the user requests them.
