3. A system for providing access to legacy systems, said system comprising:
-
a transaction request broker; and
an interface process;
wherein said transaction request broker receives a first message requesting legacy system data, determines which legacy systems provide the data and generates one or more data requests to the interface process, based on which legacy systems provide the requested data;
wherein said interface process receives the data requests from said transaction request broker, conducts transaction sessions with the legacy systems based on the data requests in order to retrieve the data, and upon completion of the sessions returns the data to said transaction request broker; and
wherein said transaction request broker further collects the data returned by said interface process and formats the returned data into a reply message. - View Dependent Claims (4, 5, 6, 7)
