In this post I want to reply to all my readers which wrote to me in the past weeks asking to me to suggest some interesting resources for beginners to learn Object Oriented Design methodology.

This is a small list with some basic references about Object Oriented Design process and it includes an UML guide, some articles about how to write OO javascript, PHP and Perl code. I also included some video tutorials about an useful introduction to OO PHP. If you have some interest link to suggest about this topic, please leave a comment, thanks!


UML Guide
The Unified Modeling Language is a standard design specification that is overseen by the Object Management Group (OMG). UML provides a nice framework for designing and analyzing process, structure and their relationships. UML is a collection of the best technical modeling specifications and practices is use today. It is mainly used in developing software requiring Object Oriented Analysis (OOA) and Object Oriented Design (OOD).

Design Patterns | Object Oriented Design
Design Patterns OODesign provides general design principles about Object Oriented Design with some well explained tutorials and examples about this topic.

Object Oriented Analysis and Design
OOAD.com provides a lot of interesting link about Object Oriented Analysis and Design resources, forums, links, basic methodology, book and programming roadmap.

Object Oriented Design with Javascript
This is a serie of three article which discuss object-oriented features of JavaScript. Part one provides background on how JavaScript supports the main principles of object-oriented programming. Part two demonstrates how JavaScript constructs can be used to build a class inheritance framework and write scripts supporting a JavaScript class hierarchy. The third and final part shows how to use the JavaScript class framework to build object-oriented client-side abstractions of ASP.NET user controls.

Javascript is not a OOP (Object Oriented Programming) Language, but it supports objects, so why don’t use them? It may not be the best thing if you just want to create some small scripts, but as soon as you do a bit more than just reading some data from a form, it can definitely make sense to use objects, because it’s much easier to reuse this code later on. Take a look at this interesting post about this topic from nino.net.

Object Oriented Ajax Application Design
Greg Brown explains how to use basic object-oriented techniques to build more robust AJAX applications. The demands on JavaScript as a development platform are growing with the increasing popularity of so-called AJAX applications. The procedural development model commonly used to add basic client-side interactivity to web pages today will not scale to support the level of UI complexity required by these applications. Fortunately, and contrary to popular belief, it is possible to apply object-oriented (OO) design principles in JavaScript, which can help manage this complexity.

SUN | The Java Tutorials
If you've never used an object-oriented programming language before, you'll need to learn a few basic concepts before you can begin writing any code. This lesson will introduce you to objects, classes, inheritance, interfaces, and packages. Each discussion focuses on how these concepts relate to the real world, while simultaneously providing an introduction to the syntax of the Java programming language.

- What Is a Class?
- What Is Inheritance?

Object Oriented PHP for Beginners
Stefan Mischook wrote this practical tutorial to teach total beginners object oriented PHP. So before you begin, get out your favorite PHP code editor and be ready to write and run some object oriented PHP code. You can also download a PDF version of this tutorial or watch the following videos:

Perl Object Oriented Programming
Most people are not aware of the fact that Perl has support for object-oriented programming. If you've used another object-oriented programming language such as Java or C++ or been exposed to object-orientation, then object oriented programming in Perl is nothing like that. To do real useful object-oriented programming in Perl take a look at this article.
