Homework 3

Due Thursday, October 8

The purpose of this exercise is to give you familiarity with using a version control system (or revision control system) to share code among members of a development team. Basically, you will create a repository for the Login application you wrote last week, and then add new features to it, working individually and using the repository to manage your contributions.

Read the appropriate sections of Fogel (starting on page 60) to get an overview of version control systems and how they work.

Read the following SVN tutorial to familarize yourself with how it works.

For this assignment we will be using a SVN Subversion server. Read about the Tigris project that has created and maintains SVN. You should all have accounts on the CPSC Department's SVN server.

Create a repository for your project, initializing it with the code you developed last week. Then working individually, add the following enhancements to your code:

• Enhancement #1: Add two new tables to your database. The first table stores usernames (or userids) and course numbers (CPSC225, etc.), representing the courses that the student is taking. The second table stores course numbers as key and the associated course name. Then modify the current app so that, following a successful login, the app returns a list of a user's courses and course names.

• Enhancement #2: Add some Javascript error checking to the login process, catching empty username and password fields before submitting the form to the server.

• Enhancement #3: Add logout capability to the page showing the user's courses. This will require the app to close the connection to the database and to end the Apache session.

• Enhancement #4: Add a form to the page showing the user's courses that allows the user to add a new course to the list of courses. When this form is submitted, the page returned should display the same page, but with the new courses added to the list.

Handin instructions: Post your source code in a readable directory and post a link to your well-documented, well-structured source code to the CPSC225 wiki.
