Academic Integrity

Students are expected to adhere to the Academic Integrity policies of Roanoke College. All work submitted for a grade is to be strictly the work of the student unless otherwise specified by the instructor. The policies as outlined in the Academic Integrity handbook will be enforced in the course.

Graded programs are subject to the Roanoke College Academic Integrity policies. Copying a program or a portion of a program (even a single line) or reading another person's program to obtain ideas for solving a problem is plagiarism. Other examples of integrity violation include writing code for someone else, using code written by someone else, telling someone else how to solve a problem or having someone tell you how to solve a problem (and using their method). These cases apply to any work that is handed in for a grade under the instructor's assumption that the work is your own. Unless specified otherwise by the instructor, discussion among students should be limited to general discussion of concepts and language details, not specific aspects of a solution to the assigned problem.

Class Attendance

Regular attendance is highly recommended. Regardless of attendance, students are responsible for all material covered or assigned in class.


There will be two one-hour tests (Sept. 26, and Oct. 31) in class and one final exam (Friday, December 12, 2003, 8:30am -- 11:30am). Make-up tests will be available by pre-arrangement only in case of scheduling conflicts. After the test, make-ups will be available only in case of documented medical emergency.

Besides the exams, there will be regular homework assignments, projects and quizzes in class.

Programming projects: In the second half of the semester, we will work with the data base management system postgresql. There will be two projects assigned during that time. Projects will be graded on correctness, style and documentation. Projects are due by 5:00pm on the assigned date. Late projects will be penalized 10% per day, and will not be accepted more than three days late.

Quizzes: There will be short quizzes in class. These will be announced at least one class period in advance. There will be no make-ups for missed quizzes.



The final grade will be computed based on the grades in the tests, the final exam, home works, quizzes and projects according to the following weights.

Component Weight
Home works15%
Projects (2)20% (10% each)
One-Hour Tests (2)30% (15% each)
Final Exam20%

The grading scale is as follows:
