In this paper, we envision an approach for the automatic generation of a user interface (UI) prototype from a system domain model (or core model), that captures the main domain entities and transactions, and a system use case model, which captures the intended user tasks. This prototype allows the early validation of executable core system models, and can be used as a basis for subsequent developments.The envisioned solution uses OCL to add preciseness and semantic richness both to the domain and use case UML models. The generated UI provides some usability enhancements that are derived from the model's pre-conditions.

Model-driven development (MDD)

Model-Based/Driven Development (MDD) constitutes an approach to software design and development that potentially contributes to: concepts closer to domain and reduction of semantic gaps, automation and less sensitivity to technological changes, and the capture of expert knowledge and reuse. The widespread adoption of pervasive technologies as basis for new systems and applications lead to the need of effectively design pervasive information systems that properly fulfil the goals they were designed for. This paper presents a profiling and framing structure approach for the development of Pervasive Information Systems (PIS). This profiling and framing structure allows the organization of the functionality that can be assigned to computational devices in a system and of the corresponding development structures and models, being. The proposed approach enables a structural approach to PIS development. The paper also presents two case studies that allowed demonstrating the applicability of the approach.

This chapter focus on design methodologies for pervasive information systems (PIS). It aims to contribute for the efficiency and effectiveness on software development of ubiquitous services/applications supported on pervasive information systems. Pervasive information systems are composed of conveniently orchestrated embedded or mobile computing devices that offer innovative ways to support existing and new business models. Those systems are characterized as having a potential large number of interactive heterogeneous embedded/mobile computing devices that collect, process, and communicate information. Additionally, they are target of high rates of technological innovations. Therefore, changes on requirements or in technology demands for frequent modifications on software at device and system levels. Software design and evolution for those requires suitable approaches that cope with such demands and characteristics of pervasive information systems. Model-driven development approaches (which essentially centre the focus of development on models, and involves concepts such as Platform-Independent Models, Platform-Specific Models, model transformations, and use of established standards) currently in research at academic and industrial arenas to design of large systems, offer potential benefits that can be applied to design and evolution of these pervasive information systems. In this chapter, we raise issues and propose strategies related to the software development of PIS using a model-driven development perspective.

Abstract. Pervasive computing is a research field of computing technology that aims to achieve a new computing paradigm. Software engineering has been, since its existence, subject of research and improvement in several areas of interest. Model-Based/Driven Development (MDD) constitutes an approach to software design and development that potentially contributes to: concepts closer to domain and reduction of semantic gaps; automation and less sensitivity to technological changes; capture of expert knowledge and reuse. This paper presents a profiling and framing structure approach for the development of Pervasive Information Systems (PIS). This profiling and framing structure allows the organization of the functionality that can be assigned to computational devices in a system and of the corresponding development structures and models, being. The proposed approach enables a structural approach to PIS development. The paper also presents a case study that allowed demonstrating the applicability of the approach.Keywords: MDD, PIS, pervasive, ubiquitous, software engineering, process, information systems, architecture, framework. IntroductionThe dissemination of computing and heterogeneous devices and platforms, the high pace of technological innovations and volatile requirements, the size and complexity of software systems characterize the software development context today. This context challenges the way software is developed for emerging forms of information systems. Software Development Processes (SDPs), as well as generalized adoption of models, are fundamental to efficient development efforts of successful software systems. Pervasive Computing, also called Ubiquitous Computing [1,2], represents a new direction on the thinking about the integration and use of computers in people's lives. It aims to achieve a new computing paradigm, one in which there is a high degree of pervasiveness and availability of interconnected computing devices in the physical Profiling and Framing Structures for Pervasive Information Systems Development 285 environment. Widespread availability of affordable and innovative information technologies represents a potential opportunity for improvement/innovation on business processes or for enhancement of life quality of individuals. Among other things (such as social concerns), this opportunity promotes the attention to the efficiency and effectiveness of information management regarding to the way they acquire, process, store, retrieve, communicate, use, and share information. To take full benefits of the opportunities offered by modern information technologies, these devices need to be "appropriately integrated within organizational frameworks" [3]. Therefore, Pervasive Information Systems (PIS) [4] orchestrate these devices in order to achieve a set of well-established goals. In this way, PIS not only provide a solid basis to sustain the needed information to achieve effectiveness at both individual and organizational levels, but also leverages the investment on those information techno...
