Abstract: An object oriented interactive application interface for facilitating application program development in a networked computer system providing on-line services is disclosed. The present invention is an Interactive Application Object module (IAO), comprising a client side portion and a server side portion, that facilitates the development of client applications for interaction with a server across a network. The IAO comprises a set of software objects that include interfaces and methods for implementing a client on-line service application at a high abstraction layer. The IAO provides high level objects for use by a client application for handling a large set of interactive system and business functions. On the client device, the IAO insulates the client application from the implementation details of a particular low level network interface.
