IntroductIon Data warehouses (DWs) integrate data from different source systems in order to provide historical information that supports the decision-making process. The design of a DW is a complex and costly task since the inclusion of different data items in a DW depends on both users' needs and data availability in source systems. Currently, there is still a lack of a methodologi-cal framewo...

Our Requirements for a Workload Generator Empirical evaluation of our research in • Software performance evaluation (van Hoorn, 2007) • Timing behavior anomaly detection and automatic fault localization (Rohr, 2008) • Runtime reconfiguration (Matevska and Hasselbring, 2007) Desired features • Workload specification should be • Maintainable, • Reusable, and • Application-generic • Probabilistic ...

This paper presents Executable Use Cases (EUCs), which constitute a model-based approach to requirements engineering. EUCs may be used as a supplement to Model-Driven Development (MDD) and can describe and link user-level requirements and more technical software specifications. In MDD, user-level requirements are not always explicitly described, since usually it is sufficient that one provides ...

Despite significant advances in the access control domain, requirements of new computational environments like web services still raise new challenges. Lack of appropriate method for specification of access control policies (ACPs), composition, verification and analysis of them have all made the access control in the composition of web services a complicated problem. In this paper, a new indepe...

Collaborative, visual design tools are typically difficult to build and evolve. We describe a meta tool for specification and generation of multiple view, multiple user visual design tools. The tool permits rapid specification of visual notational elements, underlying tool information model requirements, visual editors, the relationship between notational and model elements, and behavioural com...

This paper presents a language called ScreenSpec that can be used to specify screens at requirements elicitation phase. ScreenSpec was successfully applied in 8 real projects. It is very effective: average time needed to specify a screen is 2 minutes, and takes an hour to become proficient in using it. Visual representation generated from ScreenSpec can be attached to requirements specification...

Abstract Requirements engineering and requirements management are essential sub-processes of product development an integrated part virtually all models industrial process descriptions. Proprietary context specific processes for working with used in design practice. However, these not appropriately reflected existing development. Existing standards describe the content generation documents but ...

Context. Requirements changes are unavoidable in any software project. Requirements change over time as software projects progress, and involved stakeholders (mainly customers) and developers gain better understanding of the final product. Additionally, time and budget constraints prevent implementing all candidate requirements and force project management to select a subset of requirements tha...

We adapt in this paper an analysis-revision cycle to the SCTL-MUS methodology which we will use to support the modification and evolution of requirements specifications in a multi-perspective environment. We take advantage of using our approach in the analysis and revision phases, being able to translate the diagnostic information into system requirements refinements close to the system domain ...
