This paper presents a framework for reasoning about the semantic impact of aspect weaving at the level of early design modeling. The framework is based on semantic consistency between a model and its projection in the woven model. If a weaving preserves the semantic consistency between the model and its projection, then it has no impact on the model. The underlying formalisms are Process Algebras...
This paper presents a model for architecture level aspect weaving. Its underlying formalism is process algebra. In the model, the base model and aspect models are specified as labeled transition systems, while aspect weaving is interpreted as an algebraic operation between the base model, aspect models and the woven model. Through the model, the logic relationship between the woven model and the base...
Security is a requisite and vital concern that should be addressed in e-commerce systems. Traditionally, to add security properties to the application, developers had to specify when, where and how to apply what security policies manually. Such a process is often complicate and error-prone. This paper describes an aspect oriented approach to separating security and application concerns at the architecture...
