"This book is indispensable to the serious SPARK user, giving a complete description of the enhanced SPARK language and analysis capabilities." --Phil Thornley, Specialist in Safety Critical Software, BAE Systems. "The SPARK approach provides a means by which good software engineering can bepracticed and be seen to be practiced. The book provides a rich description ofand rationale for the language, and could form the foundation for guidelinesused in the programming and verification of safety critical systems." --George Romanski, President, Verocel Inc. "John Barnes has used his characteristic witty style to provide the reader with all they need to understand and to start using the elegant features of the SPARK high integrity language and toolset." --S. Tucker Taft, President, SofCheck Inc., and lead designer of Ada 95. Our lives depend -- quite literally -- on software. Banking, transport, medical and industrial control systems rely on software to function correctly. In a software-powered world it is vital for our systems to be secure, reliable and safe. The SPARK language and tools are designed to support the construction of "high integrity" systems, where safety and security are paramount. SPARK has been applied successfully in diverse applications including railway signalling, smartcard security and avionics systems in the Lockheed C130J and EuroFighter "Typhoon" projects. The CD-ROM accompanying the book containsa demonstration version of the SPARK toolset and its documentationcode examples from the text of the bookAonix ObjectAda compiler Special Edition GNAT Compiler public edition John Barnes, in his clear and urbane style, combines a full description ofSPARK with practical advice on using the SPARK tools. Numerous examples and case studies show readers how they can create more reliable software.

Computing systems are of growing importance because of their wide use in many areas including those in safety-critical systems. This book describes the basic models and approaches to the reliability analysis of such systems. An extensive review is provided and models are categorized into different types. Some Markov models are extended to the analysis of some specific computing systems such as combined software and hardware, imperfect debugging processes, failure correlation, multi-state systems, heterogeneous subsystems, etc. One of the aims of the presentation is that based on the sound analysis and simplicity of the approaches, the use of Markov models can be better implemented in the computing system reliability.

Computer software - Computer software (or simply software) is that part of a computer system that consists of encoded information (or computer instructions), as opposed to the physical computer equipment (hardware) which is used to store and process this information. The term is roughly synonymous with computer program but is more generic in scope.

System software - System software is a generic term referring to any computer software whose purpose is to help run the computer system. Most of it is responsible directly for controlling, integrating, and managing the individual hardware components of a computer system.

Daemon (computer software) - In Unix and other computer multitasking operating systems, a daemon is a computer program that runs in the background, rather than under the direct control of a user; they are usually instantiated as processes. Typically daemons have names that end with the letter "d"; for example, syslogd is the daemon which handles the system log.

Computer system - A computer system consists of a set of hardware and software which processes data in a meaningful way. The personal computer or PC exemplifies a relatively simple computer system.
