Category theory is a general mathematical theory of structures and of structures of structures. It occupied a central position in contemporary mathematics as well as computer science. This book describes the history of category theory whereby illuminating its symbiotic relationship to algebraic topology, homological algebra, algebraic geometry and mathematical logic and elaboratively develops the connections with the epistemological significance.

Object technology pioneer Wirfs-Brock teams with expert McKean to present a thoroughly updated, modern, and proven method for the design of software. The book is packed with practical design techniques that enable the practitioner to get the job done.

Object Thinking blends historical perspective, experience, and visionary insight - exploring how developers can work less like the computers they program and more like problem solvers.

Tool-Being offers a new assessment of Martin Heidegger's famous tool-analysis, and with it, an audacious reappraisal of Heidegger's legacy to twenty-first-century philosophy. Every reader of Being and Time is familiar with the opposition between readiness-to-hand (Zuhandenheit) and presence-at-hand (Vorhandenheit), but commentators usually follow Heidegger's wishes in giving this distinction a limited scope, as if it applied only to tools in a narrow sense. Graham Harman contests Heidegger's own interpretation of tool-being, arguing that the opposition between tool and broken tool is not merely a provisional stage in his philosophy, but rather its living core. The extended concept of tool-being developed here leads us not to a theory of human practical activity but to an ontology of objects themselves. Tool-Being urges a fresh and concrete research into the secret contours of objects. Written in a lively and colorful style, it will be of great interest to anyone intrigued by Heidegger and anyone open to new trends in present-day philosophy.

Concern identification aims to find the implementation of a functional concern in existing source code. In this work, concerns are described, using the Hierarchic Concern Model, as gray-boxes containing subconcerns, inputs, and outputs. The inputs and outputs are used as concern seeds to identify data-oriented abstractions of concern implementations, called concern skeletons. The identification approach is based on context free language reachability and supported by a tool, called CoDEx.

Object-Process Methodology (OPM) is an intuitive approach to systems engineering. This book presents the theory and practice of OPM with examples from various industry segments and engineering disciplines, as well as daily life. OPM is a generic, domain independent approach that is applicable almost anywhere in systems engineering.

Are you looking for a more effective approach to real-time systems development? Real-Time Object-Oriented Modeling The development of real-time distributed systems is one of the most difficult engineering problems ever faced, taxing the capabilities of traditional real-time software development approaches. Real-Time Object-Oriented Modeling is the first book that brings together, in a single harmonious approach, the power of object-oriented concepts tailored specifically for real-time systems, with an iterative and incremental process based on the use of executable models. Developed by practitioners, the proven methodology described here is becoming a leader in the industry. Using a learn-by-example approach, this book offers: * A single consistent set of graphical modeling concepts, chosen to improve developer effectiveness, which apply uniformly to analysis, design, and implementation. This reduces the learning curve to master the entire method and eliminates expensive discontinuities across different stages of development. * An approach to the object paradigm that is easy to learn and that applies to the construction of reusable architectural design components, not just low-level language elements. This unleashes the true power of the object paradigm. * Techniques for constructing executable models to gain early confidence in specifications and design decisions. * Approaches to project management that deliver the benefits of the object paradigm and executable models.

The object oriented paradigm has become one of the dominant forces in the computing world. According to a recent survey, by the year 2000, more than 80% of development organizations are expected to use object technology as the basis for their distributed development strategies. Handbook of Object Technology encompasses the entire spectrum of disciplines and topics related to this rapidly expanding field - outlining emerging technologies, latest advances, current trends, new specifications, and ongoing research. The handbook divides into 13 sections, each containing chapters related to that specific discipline. Up-to-date, non-abstract information provides the reader with practical, useful knowledge - directly applicable to the understanding and improvement of the reader's job or the area of interest related to this technology. Handbook of Object Technology discusses: the processes, notation, and tools for classical OO methodologies as well as information on future methodologies prevalent and emerging OO languages standards and specifications frameworks and patterns databases metrics business objects intranets analysis/design tools client/server application development environments

“ ..... object oriented seems to be becoming in the 1980s what structured programming was in the 1970s. ” Brian Randell and Pete Lee This quotation is from the invitation to the annual Newcastle University Conference on Main Trends in Computing, September 1988. It seems to capture the situation quite well, only that the object orientation is being materialised in languages and language constructs, as well as in the style of programming and as a perspective upon the task considered. The second European Conference on Object Oriented Programming (ECOOP’88) was held in Oslo, Norway, August 15-17, 1988, in the city where object oriented programming was born more than 20 years ago, when the Simula language appeared. The objectives of ECOOP’88 were to present the best international work in the field of object oriented programming to interested participants from industry and academia, and to be a forum for the exchange of ideas and the growth of professional relationships.
