Evolution of information systems (ISs) is a multi-facetted issue that over time has proved arduous to manage. On the enterprise level of ISs, an organization's total portfolio of interconnected information systems is considered as one system – an enterprise information system (EIS), consisting of course-grained and heterogeneous components that in themselves may constitute complex ISs. In EISs,...

Software quality should be evaluated from different perspectives; we highlight the internal and external ones (ISO/IEC, 2002). Specially, internal quality evaluation depends on the software architecture (or design) and programming aspects rather than on the product behaviour. On the other hand, architectural evaluation methods tend to apply scenarios for assessing the architecture respect to qu...

Data freshness has been identified as one of the most important data quality attributes in information systems. This importance increases especially in the context of systems that integrate a large set of autonomous data sources. In this paper we describe a quality evaluation framework which allows evaluation of data freshness in different architectural contexts. We also show how this quality f...

The overall goal of the described research project was to create applicable quality assurance patterns for Java software systems using the aspect-oriented programming language extension AspectJ 5. We tried to develop aspects to check static quality criteria as a variable mutator convention and architectural layering rules. We successfully developed aspects for automating the following dynamic q...

This paper introduces the notion of Architectural Bias, which can be used to measure the influence of the architecture of Arbiter Physically Unclonable Functions (APUFs) on the quality of its outputs. A PUF design with less architectural bias is better than one which has more architectural bias. Architectural bias is the bias in the challenge-response behavior of a PUF due to the architectural ...

A software architecture is the key artifact in software design, describing the main elements of a software system and their interrelationships. We present a method for automatically analyzing the quality of an architecture by searching for architectural and design patterns from it. In addition to approximating the quality of the design, the extracted patterns can also be used for predicting the...

A key objective for ubiquitous environments is to enable system interoperability between system’s components that are highly heterogeneous. In particular, the challenge is to embed in the system architecture the necessary support to cope with behavioral diversity in order to allow components to coordinate and communicate. The continuously evolving environment further asks for an automated and o...
