    The problem-solving power of object-oriented and logic programming is discussed in terms of the dimensions of encapsulation, distribution concurrency, and reactiveness. Encapsulation and reactiveness are essential dimensions of object orientation; they support decentralized abstraction, interaction, and evolution of individual objects. Distribution is a strong two-way form of encapsulation, while ... View full abstract»

    Three object-oriented analysis methodologies and three object-oriented design methodologies are reviewed and compared to one another. The authors' intent is to answer the question of whether emerging object-oriented analysis and design methodologies require incremental or radical changes on the part of prospective adopters. The evolution of conventional development methodologies is discussed, and ... View full abstract»

    Methodological guidelines for object-oriented software construction that improve the reliability of the resulting software systems are presented. It is shown that the object-oriented techniques rely on the theory of design by contract, which underlies the design of the Eiffel analysis, design, and programming language and of the supporting libraries, from which a number of examples are drawn. The ... View full abstract»

  • Object, message, and performance: how they coexist in Self

    The Self programming language, which distills object-oriented computation down to a simple story based on copying prototypes to create objects, inheriting from objects to share their contents, and passing messages to invoke methods, is discussed. It is shown that Self's uniform application of the object-message paradigm gives programmers unusual flexibility. Unconventional optimizations can bring ... View full abstract»

    The real-time object model, an extended object-oriented model for describing real-time systems, is described. The design and implementation of RTC++, a programming language that extends C++ on the basis of the real-time object model, are discussed. The schedulability analysis and specification of rigid timing constraints in systems with active objects are reviewed.<> View full abstract»

    The architecture of the open object-oriented database (OODB) management system, its requirements, and its computational model, which builds database functionality as an extensible collection of transparent extensions to existing programming languages, are described. The way in which open OODB's system architecture is decomposed into a kernal meta-architecture and a collection of modules implementi... View full abstract»

    The Graphical Application Modeling Support system (Grams), a three-dimensional graphics system that raises the abstraction level at which the application programmer and the end user interact with the system in the image-generation process, is described. The application, graphics and rendering layers of Grams and its organization of class hierarchies are discussed. An application of the Grams syste... View full abstract»
