Abstract

Software architectures shift the focus of developers from lines-of-code to coarser-grained components and their interconnection structure. Unlike 2ne-grained objects, these components typically encompass business functionality and need to be aware of the underlying business processes. Hence, the interface of a component should re4ect relevant parts of the business process and the software architecture should emphasize the coordination among components. To shed light on these issues, we provide a framework for component-based software architectures focusing on the process perspective. The interface of a component is described in terms of Petri nets and projection inheritance is used to determine whether a component “2ts”. Compositionality and substitutability are key issues for component-based development. This paper provides new results to e8ectively deal with these issues.

N2 - Software architecture is concerned with the structure of software systems and is generally agreed to influence software quality. Even so, little empirical research has been performed on the relationship between software architecture and software quality.
