Part I: An Introduction to Object-Oriented Software Development

Part Overview

This part introduces you to a method for developing object-oriented software that is based on patterns—the insights and best practices learned by designers and users over the years—and on the modeling language (UML) that supports it.

This will not follow the object-oriented paradigm of the 1980s, where developers were simply told to find the nouns in the requirement statements and make them into objects. In that paradigm, encapsulation was defined as data-hiding and objects were defined as things with data and methods used to access that data. This is a limited view, constrained as it is by a focus on how to implement objects. It is incomplete.

This part discusses a version of the object-oriented paradigm that is based on an expanded definition of these concepts. These expanded definitions are the result of strategies and principles that arise from the design and implementation of design patterns. It reflects a more complete mindset of object orientation.

1	An introduction to the latest understanding of objects.
2	The Unified Modeling Language (UML) will then be presented. The UML gives us the tools to describe object-oriented designs in a graphical, more readily understood manner.
