Proceedings of 11th Symposium on Programming Languages and Software Tools and 7th Nordic Workshop on Model Driven Software Engineering

Robert C. Martin presented a software metric for a set of classes i.e. a package. The objective of the package level metric is to identify poorly designed packages. The Martin's metric actually consists of eight metrics which measure a few different characteristics of packages. The metric is widely known, but there is lack of theoretical and empirical evaluation of the Martin’s metric. This paper evaluates the theoretical background of the metric against an evaluation framework and presents an experimental evaluation of five open-source software applications. The theoretical validation reveals a weakness in Martin's definition for cohesion. We propose a modification which is valid according to the evaluation framework.  </div

The General Data Protection Regulation: Requirements, Architectures, and Constraints

The General Data Protection Regulation (GDPR) in the European Union is the most famous recently enacted privacy regulation. Despite of the regulation's legal, political, and technological ramifications, relatively little research has been carried out for better understanding the GDPR's practical implications for requirements engineering and software architectures. Building on a grounded theory approach with close ties to the Finnish software industry, this paper contributes to the sealing of this gap in previous research. Three questions are asked and answered in the context of software development organizations. First, the paper elaborates nine practical constraints under which many small and medium-sized enterprises (SMEs) often operate when implementing solutions that address the new regulatory demands. Second, the paper elicits nine regulatory requirements from the GDPR for software architectures. Third, the paper presents an implementation for a software architecture that complies both with the requirements elicited and the constraints elaborated.Comment: Forthcoming in the 27th IEEE International Requirements Engineering Conference (RE'19), Jeju Island, IEE
