Finding and exploiting domain models is key to success with large software systems. This intensive course will aid participants in striking a healthy balance between digging into their subject matter and addressing technological issues, which, while unavoidable, cannot be allowed to dominate the development process for commercially viable systems.

Learn to put the domain model to work, hands on.

Finding and exploiting domain models is key to success with large software systems. By cultivating a strong connection between the language used by experts, users and developers, the right kind of models can dramatically accelerate the process of translating the customers' needs into working software. Strong domain modeling coupled with programming best practices such as exploiting design patterns, refactoring, and test-driven development yield a principled yet practical approach to the development of large software systems.

This intensive course will aid participants in striking a healthy balance between digging into their subject matter and addressing technological issues, which, while unavoidable, cannot be allowed to dominate the development process for commercially viable systems.

We weave together lecture, discussion and classroom exercises, including hands-on coding projects. In discussions, attendees have the opurtunity to discuss their own experiences and relate their own work to the principles and techinques presented in the class.

Coding excercises will be done in Java for this class.
