support as thin clients running on a PC, Mac or smart phone, and the nodes
supporting the application objects as resources within the PhoneMob service
centre, where a web server validates and, when appropriate, forwards those
incoming requests to services running behind the firewall. These nodes might,
for example, be enterprise systems running PhoneMob applications on top of
JEE or various other frameworks with legacy database systems connected.

Node Architecture
The node architecture identifies a number of functions that are commonly
found in the platforms supporting application objects. Providing a technology-
neutral architecture for describing them helps to identify the commonalities
between different infrastructure solutions, such as JEE or .NET, and so makes
the integration of different platforms simpler. Several of these functions are
concerned with groupings of objects that are important when managing es-
