Web Application Design and Implementation

STEVEN A. GABARRÓ, MSc, is a member of the faculty at Stevens Institute of Technology. He created the first Web programming course at Stevens in 2003, a course which is now considered one of the most instructive computer science elective courses by students and fellow faculty. The success of the course became the drive to create this book.

"It explains all concepts at a very elementary level, and allows the novice reader (with basic knowledge of programming) to learn fundamental concepts of Web programming and practical Web design. For an experienced reader, it will provide very good overview of Web programming practices form one particular perspective, that of using open-source software tools."
