The book is an introduction to the idea of design patterns in software engineering, and a catalog of twenty-three common patterns. The nice thing is, most experienced OOP designers will find out they've known about patterns all along. It's just that they've never considered them as such, or tried to centralize the idea behind a given pattern so that it will be easily reusable.

Design Patterns: Elements of Reusable Object-Oriented Software

G eant 4 is a toolkit for simulating the passage of particles through matter. It includes a complete range of functionality including tracking, geometry, physics models and hits. The physics processes offered cover a comprehensive range, including electromagnetic, hadronic and optical processes, a large set of long-lived particles, materials and elements, over a wide energy range starting, in some cases, from 250 eV and extending in others to the TeV energy range. It has been designed and constructed to expose the physics models utilised, to handle complex geometries, and to enable its easy adaptation for optimal use in different sets of applications. The toolkit is the result of a worldwide collaboration of physicists and software engineers. It has been created exploiting software engineering and object-oriented technology and implemented in the C++ programming language. It has been used in applications in particle physics, nuclear physics, accelerator design, space engineering and medical physics.

Geant4—a simulation toolkit

In The Unified Modeling Language User Guide, the original developers of the UML--Grady Booch, James Rumbaugh, and Ivar Jacobson--provide a tutorial to the core aspects of the language in a two-color format designed to facilitate learning. Starting with a conceptual model of the UML, the book progressively applies the UML to a series of increasingly complex modeling problems across a variety of application domains. This example-driven approach helps readers quickly understand and apply the UML. For more advanced developers, the book includes a learning track focused on applying the UML to advanced modeling problems.With The Unified Modeling Language User Guide, readers will:Understand what the UML is, what it is not, and why it is relevant to the development of software-intensive systemsMaster the vocabulary, rules, and idioms of the UML in order to "speak" the language effectivelyLearn how to apply the UML to a number of common modeling problemsSee illustrations of the UML's use interspersed with use cases for specific UML features, andGain insight into the UML from the original creators of the UML.

物件導向軟體之架構(Object-Oriented Software Construction)探討

The relation as a semantic construct in an object-oriented language clearly expresses associations and constraints among objects which would otherwise be buried in implementation code. The externalization of references between objects permits a symmetric, non-redundant conceptual model which merits its own special notation and predefined operations. The object-relation model, which combines the object-oriented model with the entity-relationship model from data base theory, is particularly useful for designing and partitioning systems of interrelated objects. Relations can be implemented efficiently using hash tables. The model proposed here has been fully implemented in an object-oriented language written by the author which has been used to implement several production applications.

Relations as semantic constructs in an object-oriented language

La tendencia actual en el software lleva a la construcción de sistemas más grandes y más complejos. Esto es al hecho de que los computadores son más pequeños potentes cada año, y los usuarios, esperan más de ellos. Queremos un software que esté mejor adaptado a nuestras necesidades. Pero esto, a su vez, simplemente hace el software más complejo.También lo queremos más rápido, el tiempo de salida al mercado es otro conductor importante. La mayoría de la gente desarrolla software mediante los mismos métodos que llevan utilizándose desde hace 25 años. A menos que renovemos nuestros métodos, no podremos cumplir con el objetivo de desarrollar el software complejo que necesita actualmente. El problema del software se reduce a la dificultad que afrontan los desarrolladores para coordinar las múltiples cadenas de trabajo de un gran proyecto de software. Se necesita un proceso que integre las múltiples facetas del desarrollo. Se necesita un método común, un proceso que:

Object-Oriented Modeling and Design with UML

Of the many approaches to relational database design, the Object Modeling Technique (OMT) is particularly effective. A comprehensive explanation and two applications show the semantic improvement of OMT over other approaches.
