Ada 95, the enhanced version of the Ada programming language, is now in place and has attracted much attention in the community since the International Standard ISO/IEC 8652:1995(E) for the language was approved in 1995. The Ada 95 Rationale comes in four parts. The introductory part is a general discussion of the scope and objectives of Ada 95 and its major technical features. The second part contains a more detailed step by step account of the core language. The third part consists of several annexes addressing the predefined environment and specialized application areas. Finally, the three appendices of the fourth part are devoted to the upward compatibility with Ada 83, a few changes since the drafts of the standard were made public, and a summary of requirements.

This document describes the overall rationale for the revision of the Ada programming language and includes tutorial information for the new features. Ada 95 is a revised version of Ada updating the 1983 ANSI Ada standard (ANSI 83) and the equivalent 1987 ISO standard (ISO 87) in accordance with ANSI and ISO procedures.

Ada 2005 is the latest version of the International Standard for the programming language Ada. Formally, it is an Amendment of ISO/IEC 8652:1995 (E) rather than a completely new standard. The primary goals for the new version were to enhance its capabilities particularly in those areas where its reliability and predictability are of great value. Accordingly, a number of intriguing and attractive ideas have been included and implemented in a coherent manner as appropriate to the level of perfection necessary for the diligent maintenance of a language standard. The Ada 2005 Rationale describes not only the changes from Ada 95 but also the reason for the changes. It starts with an introduction providing a general overview and this is followed by seven chapters focusing on OOP; access types; structure and visibility; tasking and real time; exceptions, generics, etc.; the predefined library; and containers. The book concludes with an epilogue largely concerned with compatibility issues.

The purpose of this book is to help create better ADA programs by identifying and detailing a set of stylistic guidelines. This guide is ideally suited for programmers and software engineers who want to create more powerful and portable applications using ADA 95.

Ada 95: From the Beginning is a book with a dual purpose: to teach the fundamental principles of good programming, and to provide an accessible introduction to Ada 95. No previous knowledge of programming is necessary. Ada 95 has been adopted as a standard by the ISO and the third edition of this best-selling book has been revised to reflect these changes in the language. Ada 95: From the Beginning, third edition features Ada 95 throughout, presenting most of the new features of the language, especially its support for object-oriented programming; gives a detailed treatment of data structures, algorithms and top-down design; discusses modular program development, packages and abstract data types; provides an introduction to software engineering principles; and includes a wealth of examples and exercises.
