There is no single approach to modelling and model-based systems development that is best for all possible situations. Therefore, a high-level overview is needed in order to evaluate the options and identify the optimal approach. This unique textbook/reference introduces and describes in detail the SEQUAL framework for understanding the quality of models and modelling languages, including the numerous specialisations of the generic framework, and the various ways in which this can be used for different applications. Examples are provided from the application of SEQUAL in industrial and governmental settings. Topics and features: Contains case studies, chapter summaries, review questions, problems and exercises throughout the text, in addition to Appendices on terminology and abbreviations Presents a thorough introduction to the most important concepts in conceptual modelling, including the underlying philosophical outlook on the quality of models Describes the basic tasks and model types in information systems development and evolution, and the main methodologies for mixing different phases of information system development Provides an overview of the general mechanisms and perspectives used in conceptual modelling Predicts future trends in technological development, and discusses how the role of modelling can be envisaged in this landscape This didactic guide is essential reading for postgraduate students of computer science, software engineering and information systems wishing to learn more about conceptual modelling in their preparation for professional practice. Developers of information systems will also find the book an ideal reference to support their professional activity. Dr. John Krogstie is a Professor of Information Systems in the Department of Computer and Information Science at the Norwegian University of Science and Technology, Trondheim, Norway.

This volume constitutes the proceedings of the 4th IFIP WG 8.1 Working Conference on the Practice of Enterprise Modeling, held in Oslo, Norway, during November 2-3, 2011. The conference series is a dedicated forum where the use of enterprise modeling (EM) in practice is addressed by bringing together researchers, users, and practitioners in order to develop a better understanding of the practice of EM, to contribute to improved industrial EM applications, and to share knowledge and experiences. The 18 papers presented were carefully reviewed and selected from 38 submissions. Authored by both researchers and practitioners, they reflect the fact that EM encompasses human, organizational issues as well as technical aspects related to the development of information systems. The papers are organized in five thematic sessions on process modeling, business modeling, enterprise architecture, EM, and model-driven development. In addition, two keynotes on EM in an agile world and on intra- and inter-organizational process mining complete the volume.

CAiSE 2007wasthe19thinthe seriesofInternationalConferencesonAdvanced Information Systems Engineering. This year's conference was located in Tro- heim and hosted by the Norwegian University of Science and Technology, with the aimofbringingtogether practitionersand researchersinthe ?eld ofinfor- tion systems engineering. The CAiSE series thereby returned to the city where the third CAiSE conference was held in 1991. Since the ?rst CAiSE was organized in Stockholm in 1989,CAiSE has grown to become one of the most prestigious international conferences at the int- section between information systems, software engineering, database technology and other related ?elds. The CAiSE conferences present basic and applied - searchresultsfromacademiaalongsidekeynotesandresearchpresentationsfrom industry. The special theme of CAiSE 2007 was Ubiquitous Information Systems - gineering, re?ecting that modern informationsystems often span activitiesp- formed in several organizations and at di?erent geographical locations. They often support the untethered mobility of their users. Already today, these s- tems have a large impact on the everyday life of individuals and organizations. As we move towards ambient, pervasive and ubiquitous computing, this impact will increase signi?cantly.

Mobility is perhaps the most important market and technological trend within information and communication technology. With the advent of new mobile infrastructures providing high bandwidth and constant connection to the network from virtually everywhere, the way people use information resources for work and leisure is being radically transformed. The rapid developments in information technology, particularly communication and collaboration technologies, are substantially changing the landscape of organizational computing. Workers in any business area are becoming increasingly mobile. Workers in more and more areas will be required to act flexibly within the constraints of the business processes of the company (or companies) they are currently working for. At the same time they will often want to use the same information technology to support their private tasks. Over the last years, a new breed of information systems has appeared to address this emerging situation, referred to as mobile information systems. Specific applications are also being characterized as, among others, m-Commerce, m-Learning, and m-Business. This book contains the proceedings of the second IFIP TC8 Working Conference on Mobile Information Systems which was held in December 2005 in Leeds, UK and sponsored by the International Federation of Information Processing (IFIP). Mobile Information Systems II aims to: · Clarify differences and similarities between the development of mobile and more traditional information systems. · Investigate the organizational impact of mobile information systems. · Investigate the 'e to m shift' , for example in m-Commerce relative to e-Commerce. · Investigate mobile commerce applications combined with the advantages of mobile communications technologies, the drivers of which have been identified as ubiquity, accessibility, security, convenience, localization, instant connectivity, and personalization. · Evaluate existing and newly developed approaches for the analysis, design, implementation, and evolution of mobile information systems. · Investigate technical issues and the constraints they impose on mobile information systems functionalities and design.

This book contains the refereed proceedings of the 12th International Conference on Business Process Modeling, Development and Support (BPMDS 2011) and the 16th International Conference on Exploring Modeling Methods for Systems Analysis and Design (EMMSAD 2011), held together with the 23rd International Conference on Advanced Information Systems Engineering (CAiSE 2011) in London, UK, in June 2011. The 22 papers accepted for BPMDS were selected from 61 submissions and cover a wide spectrum of issues related to business processes development, modeling, and support. They are grouped into sections on BPMDS in practice, business process improvement, business process flexibility, declarative process models, variety of modeling paradigms, business process modeling and support systems development, and interoperability and mobility. The 16 papers accepted for EMMSAD were chosen from 31 submissions and focus on exploring, evaluating, and enhancing current information modeling methods and methodologies. They are grouped in sections on workflow and process modeling extensions, requirements analysis and information systems development, requirements evolution and information systems evolution, data modeling languages and business rules, conceptual modeling practice, and enterprise architecture.
