In this comprehensive introduction to Ada programming, programmers learn how to maximize the potential of this powerful language using an object-oriented methodology. Grady Booch and Doug Bryan combine their expertise to explain how to create large-scale Ada systems using good software engineering principles. Five large-scale Ada programming examples build upon these principles using an object-oriented methodology while illuminating topics such as database systems and generic tree packages. The Third Edition also incorporates more small-sized code examples, exercises based on the programming applications, a new chapter on Ada's impact on the software crisis, and an appendix on Ada 9X.
