The increasing complexity of today’s embedded systems and the increasing demand for higher quality require a comprehensive engineering approach. The model-based engineering approach that has been developed in the project SPES 2020 (Software Platform Embedded Systems) is intended to comprehensively support the development of embedded systems in the future. The approach allows for specifying an e...

In this paper we describe the tool we plan to build in order to show the feasibility of aspect oriented design and demonstrate the advantages that it implies This technique allows one to independently specify cross cutting concerns and functionnal features of a system The tool would then allow the weaving of the aspects on the model one after the other creating a design model that would comply ...

An aspect-oriented design model consists of a set of aspect models and a primary model. Each aspect model describes a feature that crosscuts elements in the primary model. Aspect and primary models are composed to obtain an integrated design view. In this paper we describe a composition approach that utilizes a composition algorithm and composition directives. Composition directives are used wh...

In earlier work, we demonstrated the successful separation of the designs of crosscutting concerns into composition patterns [1]. In this paper, we demonstrate the mapping of crosscutting designs to two programming models that support similar approaches to separation within code—AspectJ [7] and Hyper/J [5]. We first illustrate the design of the Observer pattern using the composition pattern app...

Aspect mining tries to identify crosscutting concerns in existing systems and thus supports the adaption to an aspectoriented design. This paper describes an automatic static aspect mining approach, where the control flow graphs of a program are investigated for recurring execution patterns based on different constraints, such as the requirement that the patterns have to exist in different call...

In this position paper, we propose a new generation workflow system for grid services. We observe that grid computing has become an increasingly important application domain in computer science. Grid services — a new technology based on web services — are expected to become the de facto standard for grid computing. Similar to web services, an effective mechanism is needed for the composition of...

Now that Aspect-Oriented Software Development has matured, the techniques developed in this field may be used to cleanly modularize the crosscutting concerns in legacy applications. Due to the complexity and size of these applications it is important that the identification of crosscutting concerns and the transformation into aspects is automated as much as possible. In this paper we present a ...

In this paper we initiate a discussion of a possible process to compose crosscutting concerns with the concerns they cut across. This process should be regarded as a task of an approach to manage concerns at the requirements level. The main concepts behind this process are those of match point, conflicting aspect, dominant aspect and composition rule. A match point is where one or more crosscut...

A number of requirements engineering (RE) approaches have focused on addressing broadly scoped (non-functional) properties such as security, availability, etc. More recently, several aspect-oriented requirements engineering (AORE) approaches have been proposed to tackle both functional and non-functional requirements of a crosscutting nature. In this paper, we analyse how some well-known RE app...

Aspect-oriented programming (AOP) provides assistance in modularizing concerns that crosscut the boundaries of system decomposition. Aspects have the potential to interact with many different kinds of language constructs in order to modularize crosscutting concerns. Although several aspect languages have demonstrated advantages in applying aspects to traditional modularization boundaries (e.g.,...
