Unified Modeling Language Systems Analysis Design And Development Issues

UML is a large and complex language, with many features in need of refinement or clarification, and there are different views about how to use UML to build systems. This book sheds light on such issues, by illustrating how UML can be used successfully in practice as well as identifying various problematic aspects of UML and suggesting possible solutions.

"Unified Modeling Language (UML), Unified Process (UP), and other information modeling methods are addressed in this scholarly consideration of the analysis, design, and development of web-based and enterprise applications. The most current research on conceptual, theoretical, and empirical issues of modeling for online business and static information is provided."

A modern, hands-on approach to doing SAD––in UML! Get the core skills you need to actually do systems analysis and design with this highly practical, hands-on approach to SAD using UML! Authors Alan Dennis, Barbara Haley Wixom, and David Tegarden guide you through each part of the SAD process, with clear explanations of what it is and how to implement it, along with detailed examples and exercises that allow you to practice what you’ve learned. Now updated to include UML Version 2.0 and revised, this Second Edition features a new chapter on the Unified Process, increased coverage of project management, and more examples. Highlights Written in UML: The text takes a contemporary, object-oriented approach using UML. Focus on doing SAD: After presenting the how and what of each major technique, the text guides you through practice problems and then invites you to use the technique in a project. Rich examples of both success and failure: Concepts in Action boxes describe how real companies succeeded and failed in performing the activities in the chapters. Project approach: Each chapter focuses on a different step in the Systems Development Life Cycle (SDLC) process. Topics are presented in the order in which they are encountered in a typical project. A running case: This case threaded throughout the text allows you to apply each concept you have learned.

Systems Analysis and Design: An Object-Oriented Approach with UML, Sixth Edition helps students develop the core skills required to plan, design, analyze, and implement information systems. Offering a practical hands-on approach to the subject, this textbook is designed to keep students focused on doing SAD, rather than simply reading about it. Each chapter describes a specific part of the SAD process, providing clear instructions, a detailed example, and practice exercises. Students are guided through the topics in the same order as professional analysts working on a typical real-world project. Now in its sixth edition, this edition has been carefully updated to reflect current methods and practices in SAD and prepare students for their future roles as systems analysts. Every essential area of systems analysis and design is clearly and thoroughly covered, from project management, to analysis and design modeling, to construction, installation, and operations. The textbook includes access to a range of teaching and learning resources, and a running case study of a fictitious healthcare company that shows students how SAD concepts are applied in real-life scenarios.

This book introduces and describes in detail the SEQUAL framework for understanding the quality of models and modeling languages, including the numerous specializations of the generic framework, and the various ways in which this can be used for different applications. 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 modeling, 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 modeling; predicts future trends in technological development, and discusses how the role of modeling can be envisaged in this landscape.

Five years on from its adoption in 1997 by the Object Management Group (OMG), the Uni?ed Modeling Language is the de facto standard for creating - agrammatic models of software systems. More than 100 books have been written about UML, and it is taught to students throughout the world. The de?nition of UML version 2 is well under way, and should be largely completed within the year. This will not only improve and enhance UML itself, including standard facilities for diagram interchange, but also make it fully integrated with other modeling technologies from the OMG, such as Meta-Object Facility (MOF) and XML Metadata Interchange (XMI). The Object Constraint Language, which has become an important vehicle for communicating detailed insights between UML researchers and practitioners, will have a much expanded speci?cation and be better integrated with the UML. The popularity of UML signi?es the possibility of a shift of immense prop- tions in the practice of software development, at least comparable to the shift from the use of assembly language to “third-generation” or “high-level” p- gramming languages. We dream of describing the behavior of software systems in terms of models, closely related to the needs of the enterprise being served, and being able to routinely translate these models automatically into executing p- grams on distributed computing systems. The OMG is promoting Model-Driven Architecture (MDA) as a signi?cant step towards this vision, and the MDA c- cept has received considerable support within the IT industry.

Overview: This text will be the first to present an object-oriented methodology from the outset for beginning Systems Analysis and Design students. It is the first book to introduce object-oriented methods without relying on classical methods to introduce key concepts or without requiring students to know Java or C++. It will presume no knowledge whatsoever about process modeling or data modeling. The widely used UML notation (unified modeling language) will be used throughout the book for all diagrams and model renderings. The key benefit to this approach is that it makes the course easier to teach and learn since many students come to this course with limited backgrounds having only taken one introductory MIS course. Also, this approach is appealing because object-oriented methodology is widely used in industry.

Information security is moving much higher up the agenda of corporate concerns. If information is our most important asset, then we must gird ourselves up for the task of protecting it properly. Information Security Management: Global Challenges in the New Millennium focuses on aspects of information security planning, evaluation, design and implementation.
