Widespread Adoption

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.

Object Oriented Analysis

The ability to correctly identify system requirements is seen by most Information Systems (IS) researchers and practitioners as essential to the design and development of effective information systems (Yadav, Bravoco et al. 1988; Vessey 1994). Requirements are used to drive all subsequent stages of systems development and are critical to system validation. Incorrect requirements or poorly specified requirements usually produce systems that require major revisions or are abandoned entirely (Pressman 1996). Recently, many new techniques and methodologies have been introduced to assist analysts and users in efforts to identify and specify system requirements (Coad, North et al. 1995) (Pancake 1995). One of the newest approaches to be used in this effort to improve requirements analysis is the application of object oriented analysis (OOA).

Clear Idea

This chapter, based on analysis of literature, introduces a definition and a layered architecture for government information systems. It argues that the interoperability of information systems is essential in providing integrated government services, but unfortunately there is no consensus on what interoperability is and what constitutes interoperable information systems. By analysing available academic literature and government reports on interoperability, the authors have attempted to address this problem. Based on the study, a comprehensive definition of interoperability is presented here. Further, the authors have identified four constituents of interoperable system and finally, a layered architecture for interoperability of government information systems has been presented. The authors believe that an unambiguous definition and clear idea about constituent of interoperability would remove much confusion in conceptualisation, design, and development of interoperable systems in government.

Land Information Systems

In general, land information includes all information that is related to the land and its resources. Among the necessary considerations in the design and development of a land information system, the topological aspects are fundamental as they refer to the interconnectivity of the information. Graph and information theoretic considerations, based on the natural topology of the information, are also required for system analysis, optimization and other purposes. Some practical aspects of these considerations are briefly discussed with suggestions for further studies and investigations.

Survey Data in an Information System of the Urban Physical Environment

Information Process

The surveying profession has the opportunity to make an important contribution towards the design and development of information systems of the urban physical environment. However, the achievement of this role will require an awareness of the urban information process and, more especially, an understanding of the needs for urban information. This can only be attained through a rigorous urban surveying research program.
