Software, which makes all of this data processing possible, must be robust, dependable, and easy to use. Accordingly, people who develop software should use sound methodologies to achieve these properties; this book helps with just that. … clearly and thoroughly explains the fundamental concepts of software development, with the help of many figures and tables. … Although the book is heavily centered on free and open-source software, and is organized as a textbook, individual programmers and teams of programmers can easily use it as a guide.

Integrating project work in computing courses is highly valuable. Project-driven learning experiences are enhanced when students are exposed to real-life problems and actually engaged with community partners, whether industry, business, or nonprofit organizations. While all this sounds very convincing in theory, making it a reality is a big challenge. Software Development: An Open Source Approach is an excellent resource for teachers and students to take on this challenge. The book’s RMH Homebase case study and web site supporting materials, RMH Homebase code base releases, and staging server setup instructions transform an individual reading experience of a well-written textbook into a collective software development effort that is productive, effective, and, above all, captivating.
