Architecture elements for highly-interactive business-oriented applications

Abstract

It is now widely recognized that powerful architecture elements are needed for implementing highly-interactive business-oriented applications during at least two stages of the whole lifecycle, namely the specification and the design. In this paper, we deal with the architecture model of the TRIDENT project, which introduces three components: the semantic core component, the dialog component and the presentation component. This is a hierarchical object-oriented architecture relying on the use of three kinds of objects: application objects, dialog objects, and interaction objects. Specification and rule languages are given for developing the dialog component. An abstract data model is used for characterizing the application objects. Selection rules are given for choosing appropriate interaction objects for the presentation component according to the abstract data model and to the user level.
