An Information Store and Retrieval Facility on CORBA

Abstract

In this paper, we propose an Information Storage and Retrieval Facility based on the CORBA. This facility provides information search, retrieval and storage service. To define these services, we referred the Z39.50 and defined a set of interfaces by CORBA IDL. In addition, other information storage respect services, such as information update, information update notify, and information version control etc., and more other services, such as initial service, close service, and search command forward and distribution etc., were provided in this facility. Based on this facility, programmer can add the capability of query Z39.50 server into applications and also can integrate various data sources and provide an uniform interface. Finally, we also implement an experimental library management system to verify our design.
