Abstract
The system for organizing communication among applications in a data processing network includes data bases and data base control means. The data bases include method entries, message entries, and class entries. Method entries refer to commands or other mechanisms used to invoke applications. Message entries each represent a type of operation which can be performed on instances in a class which correspond to that message and identify a method map which contains one or more references to method entries stored in the data base. Class entries, each of which is unique in a data base, contain information about classes consisting of instances which have common characteristics as well as identifying a corresponding group of message entries. The data base control means includes an invoker for identifying a method entry corresponding to the instance identifier and type of operation identified in a request for remote invocation of an application, and a dispatcher for transmitting the command identified in the method entry to the remote application. The system may include data bases in a data processing network comprised of one or more platforms or nodes and may be either global data bases ac…
