Exploring the Educational Benefits of Introducing Aspect-Oriented Programming Into a Programming Course

This paper explores the educational benefits of introducing the aspect-oriented programming paradigm into a programming course in a study on a sample of 75 undergraduate software engineering students. It discusses how using the aspect-oriented paradigm, in addition to the object-oriented programming paradigm, affects students' programs, their exam results, and their overall perception of the theoretically claimed benefits of aspect-oriented programming. The research methodology, consisting of automating the analysis of student-created computer programs, administering surveys, and collecting exam results, provided an objective measurement of the benefits of the paradigm for novice programmers, as well as evaluating their perception of its usefulness. The results show that the use of aspect-oriented programming as a supplement to object-oriented programming enhances the productivity of novice program code software engineering students and leads to increased understanding of theoretical concepts. Students readily accepted the new paradigm and recognized its benefits.

Parallel evolutionary computation in bioinformatics applications

A large number of optimization problems within the field of Bioinformatics require methods able to handle its inherent complexity (e.g. NP-hard problems) and also demand increased computational efforts. In this context, the use of parallel architectures is a necessity.In this work, we propose ParJECoLi, a Java based library that offers a large set of metaheuristic methods (such as Evolutionary Algorithms) and also addresses the issue of its efficient execution on a wide range of parallel architectures. The proposed approach focuses on the easiness of use, making the adaptation to distinct parallel environments (multicore, cluster, grid) transparent to the user. Indeed, this work shows how the development of the optimization library can proceed independently of its adaptation for several architectures, making use of Aspect-Oriented Programming. The pluggable nature of parallelism related modules allows the user to easily configure its environment, adding parallelism modules to the base source code when needed.The performance of the platform is validated with two case studies within biological model optimization.

Mapping High-Level Business Rules To and Through Aspects

RESUME. ABSTRACT.Many object-oriented software applications contain implicit business rules. Although there exist many approaches that advocate the separation of rules, the rules'connections still crosscut the core application functionality, which impedes reuse, either anticipated or not. Moreover, ultimately business rules are implemented in a programming language, which de- creases understandability and accessibility by domain experts. We propose a high-level domain model for representing domain concepts, business rules about these concepts, and connections of business rules to the core application in terms of these concepts. The link to the implementa- tion is invisible to domain experts and encapsulated in amapping. The novelty and contribution of our approach is the use of Aspect-Oriented Programming (AOP) on two levels. First of all, elements from the high-level domain model are mappedto existing implementation entities of an application developed in Object-Oriented Programming (OOP) or AOP. Secondly, new im- plementation entities are generated in order to map domain model elements that do not have a direct realisation in the current implementation or that appear as a result of domain evolu- tion. As the new implementation entities can result in crosscutting, the mapping occurs through AOP. We evaluate our approach in theWeb Services Management Layer (WSML), a non-trivial application for creating applications using Web Services, by means of two scenarios: (1) ex- tracting implicit business rules from the WSML and representing them in a high-level domain model, and (2) extending the WSML with unanticipated business rules.

Guest Editors' Introduction: Aspect-Oriented Programming

You can measure a software system's value by its modularity. The more modular the system, the easier it is to produce and extend. Aspect-oriented programming technologies aim to improve system modularity by modularizing crosscutting concerns. Global properties and programming and design issues can lead to crosscutting concerns--for example, error handling or transaction code, interacting features, and reliability and security. The guest editors introduce aspect-oriented programming and describe this special issue's articles, which explain the use of aspect-oriented programming to simplify enterprise and system software, the need to expand an interface's meaning in the presence of aspects, and the application of aspects to design and requirements activities.
