Goals


Become familiar with object-oriented analysis and program design, and with industry-standard practices of an object-oriented approach to software development.

The primary goal of this course is to become a much better programmer.

The instructor will share decades of experience as a successful software developer in industry, government, and scientific research institutions. The programming examples will be mostly in C++, but the material will apply well to other object-oriented languages such as Java and Ruby.

You will develop the critical job skill of working in a small project team to successfully develop a software application that uses shared interfaces and data formats. Your application can then interact with applications from other teams to exchange data and results.
