“…The modeling techniques may be categorized based on the ontological perspectives they apply to the application domain (Leppänen 2005). Machado, et al (2005) refer to these ontological categories as meta-model characterizations. Table 2 provides a summary of meta-model categories and some of the associated modeling approaches.…”

Requirements have remained one of the grand challenges in the design of software intensive systems. In this paper we review the main strands of requirements research over the past two decades and identify persistent and new challenges. Based on a field study that involved interviews of over 30 leading IT professionals involved in large and complex software design and implementation initiatives we review the current state-ofthe-art in design requirements management. We observe significant progress in the deployment of modeling methods, tools, risk-driven design, and user involvement. We note nine emerging themes and challenges in the requirement management arena: 1) business process focus, 2) systems transparency, 3) integration focus, 4) distributed requirements, 5) layered requirements, 6) criticality of information architectures, 7) increased deployment of COTS and software components, 8) design fluidity and 9) interdependent complexity. Several research challenges and new avenues for research are noted in the discovery, specification, and validation of requirements in light of these requirements features.

“…Bourque et al (1999) point out that requirements analysis is critical to the success of a software solution. Machado et al (2005) emphasise that a requirement model is essential to explain and share the views in human mind about complex problems, in designing and implementing successful solutions. Thus, we posit that a comprehensive requirement model is a key to developing solutions for DQ problems.…”

A pattern based approach for data quality requirements modelling

Data quality (DQ) is a critical issue in today's information systems. Both academic researchers and industry practitioners have contributed to addressing the problem of data quality through management strategies and technological advancements over the last three decades, yet data quality management remains a challenge in the organizational management portfolio. Requirement models have been used successfully to develop solutions in areas like software and database development. The current state of the art in DQ management methodologies developed by both academic researchers and industry practitioners have largely overlooked the area of DQ requirements modelling and analysis. However DQ requirements are fundamental to DQ management since the ultimate purpose of DQ management is to develop solutions to satisfy the DQ requirements. Thus, a clearly defined DQ requirement model is a necessary prelude to systematically develop solutions to organizational DQ problems. In this research, we have developed a repository of thirty-three DQ patterns to model DQ requirements. The patterns are rich in representing the real world DQ requirements while free from notational complexities, thereby allowing them to be used practically to support DQ management. We used design science as the guiding methodology for developing DQ patterns while maintaining a rationale for the rigor and the relevance of our artefacts through appropriate validations and verifications throughout the design process. One of the challenges faced in the conceptualization of DQ patterns was the lack of shared understanding among researchers about DQ dimensions, which is a key concept in representing a DQ requirement. Owing to the importance of shared understanding we systematically refactor the concept of DQ dimensions by consolidating different viewpoints from both academic and practitioner community. As a secondary aim of this study, we adapted a credible requirements engineering methodology from literature to analyse and elicit DQ requirements. We demonstrate through empirical studies that by using this methodology DQ patterns can be effectively used to elicit and model DQ requirements in organizations.iii Declaration by authorThis thesis is composed of my original work and contains no material previously published or written by another person except where due reference has been made in the text.

Abstract:This paper presents a demonstration case on the successive application of a model-based technique to assist on the refinement of software logical architectures. The technique is essentially based on the transformation of use cases into object diagrams. The applicability of the technique is illustrated by presenting some results from a mobile application. For mobile software, the definition of the underlying service-oriented architecture must consider as user requirements the services themselves, the mobile operators entry points and the final clients interfaces, and use them to characterize the platform. Within the presented demonstration case, the specification of one service of the mobile application was obtained by successively applying the technique.
