Book Description
Formal Methods Fact File VDM and Z Andrew Harry Formal methods provide a means of specifying computer systems that is unambiguous,concise and well suited to the development of complex software systems for which accuracy and reliability are critical. Heavily mathematical and seemingly difficult to learn, for many they hold little appeal. Andrew Harry speaks as a programmer who has travelled the difficult route to an understanding of formal methods techniques, and knows why it’s worth the effort. He explains, in refreshingly simple terms, what formal methods are, why we need them, what should motivate our choice of methods and how to use them effectively. The book presents a novel view of formal methods, spanning the range of specification techniques. An overview of the different styles of formal notation is followed by detailed chapters on the two most popular languages, VDM and Z, consistent with the latest draft standards. There is a readable account of the underlying maths, a short introduction to semantics for proof, and a survey of tools available. Teaching aids include quick reference appendices on the notation and syntax of VDM and Z; exercises (and their solutions); and a useful glossary of terms. A more populist account than most, this book’s "informal" treatment of the subject will appeal to students and industrial programmers who want to know more but find little on the shelves for the novice.

Book Description
1 In a number of recent presentations – most notably at FME’96 –oneofthe foremost scientists in the ?eld of formal methods, C.A.R. Hoare,has highlighted the fact that formal methods are not the only technique for producing reliable software. This seems to have caused some controversy,not least amongst formal methods practitioners. How can one of the founding fathers of formal methods seemingly denounce the ?eld of research after over a quarter of a century of support? This is a question that has been posed recently by some formal methods skeptics. However, Prof. Hoare has not abandoned formal methods. He is reiterating, 2 albeitmoreradically,his1987view thatmorethanonetoolandnotationwillbe requiredinthepractical,industrialdevelopmentoflarge-scalecomplexcomputer systems; and not all of these tools and notations will be, or even need be, formal in nature. Formalmethods arenotasolution,butratheroneofaselectionoftechniques that have proven to be useful in the development of reliable complex systems, and to result in hardware and software systems that can be produced on-time and within a budget, while satisfying the stated requirements. After almostthree decades,the time has come to view formalmethods in the context of overall industrial-scale system development, and their relationship to othertechniquesandmethods.Weshouldnolongerconsidertheissueofwhether we are “pro-formal” or “anti-formal”, but rather the degree of formality (if any) that we need to support in system development. This is a goal of ZUM’98, the 11th International Conference of Z Users, held for the ?rst time within continental Europe in the city of Berlin, Germany.

Book Description
Assessing the most valuable technology for an organization is becoming a growing challenge for business professionals confronted with an expanding array of options. This 2007 book is an A-Z compendium of technological terms written for the non-technical executive, allowing quick identification of what the term is and why it is significant. This is more than a dictionary - it is a concise review of the most important aspects of information technology from a business perspective: the major advantages, disadvantages and business value propositions of each term are discussed, as well as sources for further reading, and cross-referencing with other terms where applicable. The essential elements of each concept are covered in a succinct manner so the reader can quickly obtain the required knowledge without wading through exhaustive descriptions. With over 200 terms, this is a valuable reference for non- and semi-technical managers, executives and graduate students in business and technology management.

Book Description
The focus in development methodologies of large and complex software systems has switched in the last two decades from functional issues to structural issues; this holds for both the object-oriented and the more recent component-based software engineering paradigms. Formal methods have been applied successfully to the verification of medium-sized programs in protocol and hardware design for quite a long time. However, their application to the development of large systems requires more emphasis on specification, modeling and validation techniques supporting the concepts of reusability and modifiability, and their implementation in new extensions of existing programming languages like Java. This state-of-the-art survey presents the outcome of the 9th Symposium on Formal Methods for Components and Objects, held in Graz, Austria, in November/December 2010. The volume contains 20 revised contributions submitted after the symposium by speakers from each of the following European IST projects: the FP7-IST project AVANTSSAR on automated validation of trust and security of service-oriented architectures; the FP7-IST project DEPLOY on industrial deployment of advanced system engineering methods for high productivity and dependability; the ESF-COST Action IC0701 on formal verification of object-oriented software; the FP7-IST project HATS on highly adaptable and trustworthy software using formal models; the FP7-SST project INESS on an integrated European railway signalling system; the FP7-IST project MADES on a model-driven approach to improve the current practice in the development of embedded systems; the FP7-IST project MOGENTES on model-based generation of tests for dependable embedded systems; as well as the FP7-IST project MULTIFORM on integrated multi-formalism tool support for the design of networked embedded control systems.

Book Description
This volume contains the proceedings of the 2002 symposium Formal Methods th Europe (FME 2002). The symposium was the 11 in a series that began with a VDM Europe symposium in 1987. The symposia are traditionally held every 18 months. In 2002 the symposium was held at the University of Copenhagen, as part of the 2002 Federated Logic Conference (FLoC 2002), which brought - gether in one event seven major conferences related to logic in computer science, as well as their a?liated workshops, tutorials, and tools exhibitions. Formal Methods Europe (www.fmeurope.org) is an independent association which aims to stimulate the use of, and research on, formal methods for software development. FME symposia have been notably successful in bringing together a community of users, researchers, and developers of precise mathematical - thods for software development. The theme of FME 2002 was “Formal Methods: Getting IT Right”. The double meaning was intentional. On the one hand, the theme acknowledged the signi?cant contribution formal methods can make to Information Technology, by enabling computer systems to be described precisely and reasoned about with rigour. On the other hand, it recognized that current formal methods are not perfect, and further research and practice are required to improve their foundations, applicability, and e?ectiveness.

Book Description
This book introduces SpecDB, an intelligent database created to represent and host software specifications in a machine-readable format, based on the principles of artificial intelligence and unit testing database operations. SpecDB is demonstrated via two automated intelligent tools. The first automatically generates database constraints from a rule-base in SpecDB. The second is a reverse engineering tool that logs the actual execution of the program from the code.
