EFFICIENT DEVELOPMENT OF HIGHLY REUSABLE DISTRIBUTED SYSTEMS USING THE TCAO

摘要

Currently there are neither structured nor efficient ways to develop and reuse non-trivial and complex distributed systems despite the fact that there exist numerous sources of software, components and knowledge relating to this field. In this paper we describe how we use a novel all-encompassing development methodology called the Total Components Aspect-Oriented (TCAO) methodology to efficiently and rapidly design and develop reusable distributed systems of any size, functionality and complexity. We further describe our other novel concepts of using Early Aspect-Oriented Components (EAOC) and Early Aspect-Oriented Software (EAOS), collectively known as early systemic-entities, to get an early head-start in the development process starting from the requirements engineering phase itself and spanning throughout all the phases. TCAO also encompasses the activities of deployment, maintenance and refactoring to add any further remoting functionalities if the need arises. We further describe how we use TCAO to identify, isolate and use aspects, which are systemic cross-cutting concerns, to make the analysis, design, modelling and implementations of reusable distributed systems easier to understand,manage and control. With the aid of an exemplar software system, we also describe how a non-trivial reusable distributed system can be efficiently and rapidly developed by using our methodology to facilitate technology transfer and reuse.
