COM372: Dynamic Web Design and Programming
COURSE GOALS: We seek an advanced mastery of web-development techniques that use databases to create content—HTML form objects, database connections, and server-side programming. We will use open-source MySQL as our database, structured query language (SQL), and PHP5 for programming.
TEXTS:PHP and MySQL Web Development—Fourth Edition. 2009. Luke Welling and Laura Thomson. Addison-Wesley.
The Fifth Edition will not be out in time for this semester. A pdf of the text and listings of all code samples are available on the course server as well (you will be given access in class). Used copies are available through Amazon here. Dr. Logan has 2-3 of these for $20 (contact him if interested).
Additional material will be provided from the course website and as handouts from the instructor.
FORMAT: We will have two lectures and two labs per week. Exercises will follow text examples and projects. Office hours are liberal and you are encouraged to take advantage of them.
GRADES: Programming assignments—in parallel with the text— will be graded. You are expected to attend and participate in all classes, to have completed assigned readings on time. A rubric for grading will be provided with each assignment. (Details)
PREREQUISITES: The course is for advanced students with career or program-related needs for Web applications training. Students should be familiar with Windows operating systems and with technology for static web pages, equivalent to COM271. Students who are deficient in client-side programming technique should discuss this with Dr. Logan, who will work with you to bring you fully up to speed, as needed.
