| Abstract | |
The Object-Oriented Paradigm has currently been the dominant approach for developing software. However, it suffers from the Tyranny of the Dominant Decomposition, as it does not support a suitable modularization to the implementation relative to structural concerns. As a consequence, the implementation relative to each structural concern is scattered throughout the program modules and tangled with the implementation relative to other structural concerns. Some software development approaches, such as Aspect-Oriented Software Development with Aspect and Multidimensional Separation of Concerns in Hyperspaces with Hyper/J and CME, achieve moderate success in offering mechanisms that make it possible to overcome the deficiencies of the Object-Oriented Paradigm. However, such approaches also possess deficiencies and ommissions that must be corrected in order for them to get usable in typical complex software development contexts. This work specifies a new approach, named Theme- Oriented Software Development (TOSD), which aims at overcoming some deficiencies from previous approaches through mechanisms that support the handling of implementation for every structural concern separately and the handling of implementation for every data type separately. Moreover, TOSD contains operators which are orthogonal, that is, they can be used separately or as a combination, in order to perform composition of the program modules. We show the conceptual model of TOSD and describe a case study which consists in the development of a program to demonstrate more concretely how TOSD works in practice. We do not demonstrate the superiority of TOSD for the general case, but the results we have obtained suggest that TOSD is a promissing approach which deserves a deeper investigation in future research (AU) | |
