Book excerpt: A practical approach to enhancing quality in software models using UML Version 2.0 "Despite its increasing usage, many companies are not taking the best advantage of UML and, occasionally, individuals have experienced frustration in applying its standards. Perhaps this is because they have not yet read this book!" -From the Foreword by Prof. Brian Henderson-Sellers This book presents a practical checklist approach to enhancing the quality of software models created with the Unified Modeling Language (UML) Version 2.0. The foundation for quality is set by the discussion on the nature and creation of UML models. This is followed by a demonstration of how to apply verification and validation checks to these models with three foci: syntactical correctness, semantic meaningfulness, and aesthetic symmetry. The quality work is carried out within three distinct yet related modeling spaces: * Model of problem space (MOPS) * Model of solution space (MOSS) * Model of background space (MOBS) Readers can then choose a specific quality approach according to their roles in their projects. Verification and validation checks are also organized according to these three modeling spaces, making it easier for the reader to focus on the appropriate diagrams and quality checks corresponding to their modeling space. In addition, a major element of this publication is the Strengths, Weaknesses, Objectives, and Traps (SWOT) analysis. This analysis is performed on each UML diagram, enabling readers to fully comprehend these diagrams, their advantages and limitations, and the way in which they can be used in practical projects for modeling. A consistent case study of the Lucky Insurance System is provided throughout the chapters to illustrate the creation of good quality UML diagrams, followed by application of quality checks to them. With its emphasis on quality in UML-based projects, this book is an essential resource for all quality professionals, including quality analysts, process consultants, quality managers, test designers, and testers.

Available in PDF, EPUB and Kindle. Book excerpt: The increasing complexity of industrial systems requires more efforts to be invested in the process of system verification and validation. The quality of such systems depends on the different types of techniques that are used to verify and ensure their correct functionality. The cost of maintaining systems in the latter phases of development is usually very high and may lead in most of the cases to inefficient solutions. Therefore, checking the correctness and validity of systems early in the design phase is greatly desirable. Different verification and validation techniques such as those involving testing and simulation are helpful and useful but may lack in many cases the desired level of rigor and completeness. Moreover, these conventional techniques are generally costly, laborious and time consuming. Conversely, using formal techniques, such as model-checking and program analysis along with design metrics complementary to the conventional verification techniques provides an elevated level of confidence since they are based on theoretical foundations. Systems Engineering is an interdisciplinary approach that aims to enable the successful realization and deployment of complex systems. Many modeling languages emerged in the systems engineering arena in order to provide the means for capturing and modeling of system's specifications and requirements. The most prominent languages are Unified Modeling Language (UML) 2.0 and Systems Modeling Languages (SysML). Formal verification and software engineering techniques can be applied in order to assess the correctness of different diagrams belonging to the aforementioned modeling languages. This research work presents a unified paradigm for the verification and validation of software and systems engineering design models expressed in UML 2.0 or SysML. The proposed paradigm relies on an established synergy between three salient approaches, which are model-checking, program analysis, and software engineering techniques.

This book was released on 2010-11-16 with total page 261 pages. Available in PDF, EPUB and Kindle. Book excerpt: At the dawn of the 21st century and the information age, communication and c- puting power are becoming ever increasingly available, virtually pervading almost every aspect of modern socio-economical interactions. Consequently, the potential for realizing a signi?cantly greater number of technology-mediated activities has emerged. Indeed, many of our modern activity ?elds are heavily dependant upon various underlying systems and software-intensive platforms. Such technologies are commonly used in everyday activities such as commuting, traf?c control and m- agement, mobile computing, navigation, mobile communication. Thus, the correct function of the forenamed computing systems becomes a major concern. This is all the more important since, in spite of the numerous updates, patches and ?rmware revisions being constantly issued, newly discovered logical bugs in a wide range of modern software platforms (e. g. , operating systems) and software-intensive systems (e. g. , embedded systems) are just as frequently being reported. In addition, many of today’s products and services are presently being deployed in a highly competitive environment wherein a product or service is succeeding in most of the cases thanks to its quality to price ratio for a given set of features. Accordingly, a number of critical aspects have to be considered, such as the ab- ity to pack as many features as needed in a given product or service while c- currently maintaining high quality, reasonable price, and short time -to- market.
Download or read book Framework for Automatic Verification of UML Design Models written by Vitor Nunes De Lima and published by . This book was released on 2010 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Software-intensive systems have become extremely complex and susceptible to defects and vulnerabilities. At the same time, the consequences of software errors have also become much more severe. In order to reduce the overall development cost and assure the security and reliability of the final product, it is of critical importance to investigate techniques able to detect defects as early as possible in the software development process, where the costs of repairing a software flaw are much lower than at the maintenance phase. In this research work, we propose an approach for detecting flaw at the design phase by combining two highly successful techniques in the information technology (IT) industry in the field of modeling languages and verification technologies. The first one is the Unified Modeling Language (UML). It has become the de facto language for software specification and design. UML is now used by a wide range of professionals with very different background. The second one is Model Checking, which is a formal verification technique that allows the desired properties to be verified through the inspection of all possible states of the model under consideration. Despite the fact that Model Checking gives significant capabilities to developers in order to create a secure design of the system, they are still not very popular in the UML community. There are many challenges faced by UML developers when it comes to combine UML with model checking (e.g., developer are not familiar with formal logics, the verification result is not in the UML notation, and the generation of the model checkers code from UML models is a problematic task). The proposed approach addresses these problems by implementing a new verification framework with support to property specification without using the complexity of formal languages, UML-like notation for the verification results, and a fully automatic verification process.

Available in PDF, EPUB and Kindle. Book excerpt: This book comprehensively presents a novel approach to the systematic security hardening of software design models expressed in the standard UML language. It combines model-driven engineering and the aspect-oriented paradigm to integrate security practices into the early phases of the software development process. To this end, a UML profile has been developed for the specification of security hardening aspects on UML diagrams. In addition, a weaving framework, with the underlying theoretical foundations, has been designed for the systematic injection of security aspects into UML models. The work is organized as follows: chapter 1 presents an introduction to software security, model-driven engineering, UML and aspect-oriented technologies. Chapters 2 and 3 provide an overview of UML language and the main concepts of aspect-oriented modeling (AOM) respectively. Chapter 4 explores the area of model-driven architecture with a focus on model transformations. The main approaches that are adopted in the literature for security specification and hardening are presented in chapter 5. After these more general presentations, chapter 6 introduces the AOM profile for security aspects specification. Afterwards, chapter 7 details the design and the implementation of the security weaving framework, including several real-life case studies to illustrate its applicability. Chapter 8 elaborates an operational semantics for the matching/weaving processes in activity diagrams, while chapters 9 and 10 present a denotational semantics for aspect matching and weaving in executable models following a continuation-passing style. Finally, a summary and evaluation of the work presented are provided in chapter 11. The book will benefit researchers in academia and industry as well as students interested in learning about recent research advances in the field of software security engineering.

Download or read book The Evolution of Conceptual Modeling written by Roland Kaschek and published by Springer Science & Business Media. This book was released on 2011-02-04 with total page 348 pages. Available in PDF, EPUB and Kindle. Book excerpt: Conceptual modeling represents a recent approach to creating knowledge. It has emerged in response to the computer revolution, which started in the middle of the 20th century. Computers, in the meantime, have become a major knowledge media. Conceptual modeling provides an answer to the difficulties experienced throughout the development of computer applications and aims at creating effective, reasonably priced, and sharable knowledge about using computers in business. Moreover, it has become evident that conceptual modeling has the potential to exceed the boundaries of business and computer usage. This state-of-the-art survey originates from the International Seminar on the Evolution of Conceptual Modeling, held in Dagstuhl Castle, Germany, in April 2008. The major objective of this seminar was to look into conceptual modeling from a historical perspective with a view towards the future of conceptual modeling and to achieve a better understanding of conceptual modeling issues in several different domains of discourse, going beyond individual (modeling) projects. The book contains 14 chapters. These were carefully selected during two rounds of reviewing and improvement from 26 presentations at the seminar and are preceded by a detailed preface providing general insights into the field of conceptual modeling that are not necessarily discussed in any of the chapters but nevertheless aid in conceptualizing the inner structure and coherence of the field. The chapters are grouped into the following three thematic sections: the evolution of conceptual modeling techniques; the extension of conceptual modeling to a service-oriented, peer-to-peer, or Web context; and new directions for conceptual modeling.

Download or read book Situational Method Engineering written by Brian Henderson-Sellers and published by Springer. This book was released on 2014-06-03 with total page 323 pages. Available in PDF, EPUB and Kindle. Book excerpt: While previously available methodologies for software – like those published in the early days of object technology – claimed to be appropriate for every conceivable project, situational method engineering (SME) acknowledges that most projects typically have individual characteristics and situations. Thus, finding the most effective methodology for a particular project needs specific tailoring to that situation. Such a tailored software development methodology needs to take into account all the bits and pieces needed for an organization to develop software, including the software process, the input and output work products, the people involved, the languages used to describe requirements, design, code, and eventually also measures of success or failure. The authors have structured the book into three parts. Part I deals with all the basic concepts, terminology and overall ideas underpinning situational method engineering. As a summary of this part, they present a formal meta-model that enables readers to create their own quality methods and supporting tools. In Part II, they explain how to implement SME in practice, i.e., how to find method components and put them together and how to evaluate the resulting method. For illustration, they also include several industry case studies of customized or constructed processes, highlighting the impact that high-quality engineered methods can have on the success of an industrial software development. Finally, Part III summarizes some of the more recent and forward-looking ideas. This book presents the first summary of the state of the art for SME. For academics, it provides a comprehensive conceptual framework and discusses new research areas. For lecturers, thanks to its step-by-step explanations from basics to the customization and quality assessment of constructed methods, it serves as a solid basis for comprehensive courses on the topic. For industry methodologists, it offers a reference guide on features and technologies to consider when developing in-house software development methods or customising and adopting off-the-shelf ones.
