The present invention relates to a system and methodology to facilitate data communications and data management between network entities operating in accordance with various data structures and operating environments. A managed class of application programming interfaces (API) are provided that support data communications between remote / local locations employing a first data structure and a second location supporting a second data structure (e.g., API for NET languages to access SQL Server via XML views). The managed class and associated APIs provide data transformations between such structures to facilitate communications and data management among various locations and architectures. In addition, the managed class and APIs facilitate operations between disparate object systems such as between managed and unmanaged object systems via interface support of a wrapper and associated marshalling technologies to bridge communications between such systems.

An application layer protocol is provided on top of HTTP 1.0 / 1.1 to allow for COM Automation objects to be invoked over the Internet through IIS / ISAPI servers. The format essentially encodes the automation object's name, method to invoke, and any [in], [out], [in, out] parameters that the method signature requires, packages them up into a custom MIME type and marshals it to the ISAPI dynamic link library (DLL) on the IIS / HTTP server. There, the ISAPI DLL contains the logic to unpack the SOAP request, parses it, creates the Automation object, invokes the method with the marshaled parameters, and then returns any [out] parameters to the caller / client using the SOAP protocol. It is a stateless protocol, meaning that object lifetimes only extend to one method, and are recreated between multiple calls to the object.

A system and method is provided to facilitate communications between object systems. A caller is provided having optimized in-lined functionality when initiating a remote function call between managed and unmanaged object systems, for example.
