An object-oriented software application architecture

The authors present a novel application architecture and supporting environment. The application architecture is based upon the concept of separating the application domain knowledge (including semantics, constraints, and functionality) from the application code. This application domain knowledge is embedded in a domain model that can be shared by multiple applications. This is made possible by the use of object-oriented technology. The other advantages of this separation of the domain model from the application code include: (i) the provision of a consistent view of the application domain across multiple applications; and (ii) its use as a communication and learning aid. The application architecture also supports the separation of the user-interface issues from those of application functionality. The development of a network editor application conforming to this architecture is also presented
