Introduction to Object Oriented Design
Introduction to Object Oriented
Design
- Well these days, everyone seems to
be talking about Object-Oriented Design. Well what is it?
- Object-Oriented design (OOD) is a
programming methodology which has the following
characteristics
- OOD allows programmers to more
closely model the real world than ever before.
- OOD is also a methodology which
lends itself well to rapid prototyping. Object-Oriented
programs can be built and modified very quickly because OOD
provides the programmer with excellent tools for
abstraction.
- OOD produces reusable code. Once
objects are built, it is very easy to use them in future
applications so you need not ever reinvent the wheel.
- Finally, OOD helps programmers
work in dynamic environments. Object-Oriented programs can
be modified quickly and easily as real-world requirements
change.
- Let's look at what the guru of Java
Object Orientation, Bruce Eckel
has to say,
"Object-oriented programming appeals at multiple levels. For
managers it promises faster and cheaper development and
maintenance. For analysts and designers the modeling process
becomes simpler and produces a clear, manageable design.
For programmers the elegance and clarity of the object model
and the power of object-oriented tools and libraries makes
programming a much more pleasant task, and programmers
experience an increase in productivity. Everybody wins, it
would seem.
If there is a downside it is the expense
of the learning curve. Thinking in objects is a dramatic
departure from thinking procedurally, and the process of
designing objects is much more challenging than procedural
design, especially if you are trying to create reusable
objects."
- Okay, so that was pretty abstract.
Let's step back and come at OOD from another perspective.
Perhaps some history is in order.
