Abstract:

System Configuration files in source code are created from a high level definition of the distributed system which is to be integrated. The configuration files include data such as the types and formats of data for each process on each node of the system, identification of all applications and machine types, topography and the data manipulations needed for sending messages and files and the like from an application program in a first computer language and of a first data type to an application program in a second computer language and of a second data type. Node-specific data manipulation modules are formed at each node during start-up of the system, and these modules are automatically distributed to nodes on the network having the same architecture. The invention allows applications having different physical data characteristics to communicate by using the data manipulation modules so formed to manipulate the data at the source program into a common data representation (CDR) having data types common to all of the languages represented by the system and then reconverting the data to the local representation at the destination node.
