This page is a list of various Object Oriented, OO, projects and information that I have created. The reason for this page is to show how OO should look in the World According to Dave.

This is a sample project I use when teaching my Object Oriented Design and Analysis class. It was created to show how to properly design a sub-system as a decoupled system. In my class project the class goes from requirements all the way to design. I stop short of coding because the goal of this class is to show how Object Oriented Design and Object Oriented Analysis work. The link to this page will include the requirements document, design document, and a working example of the game engine. Click here to go to the Othello page.

This is a simple single player game that forces the player to find and play out patterns to win. The interface on the engine allows for only a single patter to be match to win (all squares green) and only two colors (Red and Green) for the squares. However the game engine allows any winning pattern to be set and allows up to ten different colors to be cycled through in the toggle. The game is found here.

I was raised with a saying “When all you have is a hammer, everything looks like a nail”. This is so true and that is why in development you need all the different tools you can get. This is where design patterns come in. There is no reason to waste time and money in redeveloping the things that are already done and work. This is why design patterns are so powerful. They are well used and can help get a project moving faster. When teaching object oriented design, I start introducing design patterns. I found that taking the same small project through different design patterns help to highlight the strengths of different patterns. This lesson, so to speak, is an introduction into patterns and is found here.

One of the main ideas in Object Oriented Design is model the real world. For someone who has not done a lot of design work this idea can be rather hard to understand, or see. When I started down the Object Oriented path this was a hard concept to follow. To help understand what model the real world might look like I have done a paper and code project to show this concept. It can be found here.
