This study discusses the architectural design of an integrated system for the delivery of lectures in
a virtual environment. The architecture and description of the system components are presented with the
techniques and recommendations for the implementation of the designed system. The system architecture is
multi-tier, modular, scalable and built for adaptability to database middleware suite. All functionalities within
the application are delivered using Web Services, communicate via industry standard XML messaging and
access is purely via a web browser. The virtual classroom application utilizes an operating system with facilities
for providing users web services, data and pre-processor hypertext with a simple and consistent User Interface
corresponding to the tiers. With the object-oriented design method used in this application, three logical
categories were identified for application objects, namely, objects that deal with presentation aspects of the
application, objects that deal with the business rules and data, and objects that accept and interpret user requests
and control the business objects to fulfil these requests.
Key words: Application objects, client-tier, multiple-tier, user interface, web-tier, ,
