Goals


First goal: You'll learn the general concepts of software engineering and relevant topics of the software development process within the context of a hands-on team project. Understand the additional challenges of programming-in-the-large over programming-in-the-small.

Second goal: So that you can immediately apply software engineering concepts, you'll learn to work on a small team to build and deploy a web application using the full-stack Ruby on Rails framework, which supports important client-server concepts:

During the semester, each project team will

These are important real-world job skills for the professional software developer! This is a challenging course that will demand much of your time and effort throughout the semester.
