The following topics are dealt with: software quality; domain-specific modeling; model-driven engineering; SOA; process management; process improvement; software management; Web computing; dependable systems; and open source.
A widely adopted security mechanism is the specification of access control policies by means of the XACML language. In this paper, we propose a framework, called X-CREATE, for the systematic generation of test inputs (XACML requests). Differently from existing tools, XCREATE exploits the XACML Context Schema. In particular, the tool applies a XML-based methodology (XPT) to systematically produce a...
In this paper we present an approach of using model-driven technologies for testing of service component interactions. We report on an industrial experiment with a novel combination of existing UML standards, i.e., the UML Testing Profile (U2TP), in conjunction with proprietary domain specific languages (DSLs). Many model-based testing (MBT) approaches use the UML 2 standard, but very few of them...
Since usability requirements can have an impact on software architecture, they should be considered in the software architecture design. We present the method "Software ArchitecTure analysis of Usability Requirements realizatioN'' (SATURN) during which architects and analysts conduct well-established usability requirements engineering methods (usage context specification, walkthrough, brainstorming)...
Evaluating the performance (timing behavior, throughput, and resource utilization) of a software system becomes more and more challenging as today's enterprise applications are built on a large basis of existing software (e.g. middleware, legacy applications, and third party services). As the performance of a system is affected by multiple factors on each layer of the system, performance analysts...
Component-based software engineering has been projected off-late as an appropriate paradigm for embedded systems development. However this becomes feasible only if the dependability attributes, such as reliability, of embedded systems can be properly estimated and guaranteed using appropriate models. Another recent trend is the prevalence of architectural modelling of software systems due to the advantages...
Safety assessment of dependable systems is a complex verification task that is desirable to be explicitly incorporated into the development cycle during the very early stages of a project. The main reason is that the cost to correct a safety error at the late stages of system development is excessively high. Towards this aim, we introduce an ontology-based model-driven engineering process for automating...
Component-based development has become more common news than exotic novelty in mainstream industry. Its adoption has accrued high facilitation potential for software reuse and better organization of the product. Surprisingly however, component-oriented approaches have fared far worse in the domain of high-integrity real-time systems. One of the fundamental reasons of this difficulty stems from the...
Reusable software architectures and supporting components are the focus of an increasing number of software organizations attempting to reduce software costs. One essential attribute of reusable software architecture is that it effectively isolates the logical, or static, aspects of the application from any product specific variations in the physical architecture, or execution environment. A primary...
We present an approach to combine model-driven and component-based software engineering of distributed embedded systems. Specifically, we describe how deployment modelling is performed in two steps, and present an incremental synthesis of runnable representations of model entities on various abstraction levels. Our approach allows for flexible reuse opportunities, in that entities at different levels...
In software engineering, system construction normally starts from a requirements specification that has been engineered from raw requirements in a natural language. Such a specification is derived from intermediate requirements models such as use case models. These models at best only approximate the raw requirements. In this paper we propose a component-based approach that maps raw requirements directly...
