This book is based on a PhD dissertation which was accepted by the faculty of Law and Economics at the University of Bern, Switzerland. The ideas presented were partially developed in a research project founded by the Swiss National Sci ence Foundation in 1993 and 1994. This research project was concerned with evaluating the application of database triggers and active databases for the im plementation of business rules. We recognized among other things the lack of a methodology for modeling such business rules on the conceptual level. Therefore, this became the focus of the follow-up research which resulted in this book. All this work would not have been possible without the help of several people. First of all, I would like to give special thanks to my thesis supervisor Prof. Dr. Gerhard Knolmayer. He not only initiated the research project and found an in dustry partner, but also provided very valuable ideas, and critically reviewed and discussed the resulting publications. Furthermore, I would like to express my thanks to the second thesis supervisor Prof. Dr. Sham Navathe from Georgia In stitute of Technology who influenced my work with results from a former re search project and who agreed to evaluate the resulting PhD Dissertation.

This book constitutes the refereed proceedings of the 20th International Conference on Conceptual Modeling, ER 2001, held in Tokohama, Japan, in November 2001. The 45 revised full papers presented together with three keynote presentations were carefully reviewed and selected from a total of 197 submissions. The papers are organized in topical sections on spatial databases, spatio-temporal databases, XML, information modeling, database design, data integration, data warehouse, UML, conceptual models, systems design, method reengineering and video databases, workflows, web information systems, applications, and software engineering.

This book constitutes the thoroughly refereed joint post-proceedings of four international workshops held in conjunction with the 20th International Conference on Conceptual Modeling, ER 2001, held in Yokohama, Japan in November 2001. The 37 revised full papers presented were carefully selected and improved during two rounds of reviewing and revision. In accordance with the respective workshops, the papers are organized in topical sections on conceptual modeling and human, organizational, and social aspects; data semantics in web information systems; conceptual modeling approaches for e-business; and global data modeling.

This volume is comprised of the proceedings of the 13th International Conference on Information Systems Development held August 26th-28th, 2004, at Vilnius Gediminas Technical University, Vilnius, Lithuania. The aim of this volume is to provide a forum for the research and practices addressing current issues associated with Information Systems Development (ISD). Every day, new technologies, applications, and methods raise the standards for the quality of systems expected by organizations as well as end users. All are becoming dependent on systems reliability, scalability, and performance. Thus, it is crucial to exchange ideas and experiences, and to stimulate exploration of new solutions. This proceedings provides a forum for both technical and organizational issues.

Includes articles in topic areas such as autonomic computing, operating system architectures, and open source software technologies and applications.

Information systems often fail because their requirements are poorly defined. This book shows IT professionals how to specify more precisely and more effectively what their systems need to do. The key lies in the discovery and application of what are called business rules. A business rule is a compact and simple statement that represents some important aspect of a business. By capturing the rules for your business—the logic that governs its operation—you will gain the ability to create systems fully aligned with your business needs. In this book, Tony Morgan provides a thorough introduction to business rules, as well as a practical framework for integrating them into information systems. He shows you how to identify and express business rules, offers practical strategies for their use, and explains the key elements of logic that underpin their application. Topics covered include: Understanding the role of business rules and models in information systems development Using models to structure and manage business activities, including e-commerce Defining and discovering business rules Controlling business rule quality Fitting business rules into varied technical architectures Implementing business rules using available technology Whether you are an analyst, designer, developer, or technical manager, the in-depth information and practical perspective in this valuable resource will guide you in your efforts to build rule-centered information systems that fully support the goals of your organization.
