The invention provides improved digital data processing systems with distributed object management for use, e.g., in process control. These systems are of the type having servers and, more particularly, object request brokers (ORB's) that route requests generated by one or more clients to implementation objects maintained by a server application. Routing is based on a binding table (or other such store) that identifies dispatching procedures, or "skeletons," that invoke requested services on implementation objects specified in the requests. Such systems may be CORBA-compatible, though the improvements provided by o the invention are applicable to distributed object management systems having other architectures, as well. The improvements are characterized by the utilization of a single entry in the binding table (or other such store) to route requests to a plurality of different implementation objects, e.g., representing process control blocks and parameters, maintained by the server. In a related aspect, the improvements can be characterized as providing an CORBA-compatible ORB or, more particularly, (basic) object adapter (OA), that permits requests to be routed to implementations that are not listed in the binding table.
