Abstract

A database client/server development system providing support for remote sessions with user-created application objects is described. When a user desires to create a 'remoteable' object from a user object, the user assigns a proxy name or alias, thereby providing a mechanism to differentiate the real (local) version of the object from a remote version of that object. When the user creates the proxy, the system generates all of the interface definitions for the object (i.e., to access its internal functionality) which are capable of being proxied (i.e., 'proxiable'). A given object can reside locally, remotely, or both; the proxy mechanism allows the application to resolve at runtime which version of the object to invoke. When the user's final application is deployed, the proxy object is deployed at the client machine for use at the client for accessing the real version at the server. If desired, an application can be deployed with a real copy of the object, in addition to the proxy. In such a case, the client can serve as a server (of that object), in addition to being a client of objects from other servers.
