Paper Abstract:
|
In wide-enterprise information system, an object can change its behaviours and play different roles/views in their
lifecycle. In distributed system, the same object offers different views/roles (functional) to different users/clients, which
enjoy different privileges to core data and functionalities. Distributed platforms address one problem or the other. Our
approach, called distributed view programming, tries to address both problems. At any given point of time, an object
offers a different set of behaviours depending of the active views in that time. Therefore, a client/application user may
select a subset of existing functionalities of that object. The core object forwards a function call to a view that has to
return it to core object. In distributed platforms, there are no needs to support delegation in EJB Corba or .Net between an
object and its aspects or views because this separation doesnt exist. In this paper, we discuss a distribution issues with
view programming (VOP) and then delegation idea in distributed views-based systems. |
