Estimated CSAB Category Content 4 credits

Total Credits: 4

Laboratory Projects:

There is a coordinated series of laboratory projects designed to build a complete database application using the MS ACCESS database software. The labs illustrate and reinforce many of the concepts introduced in the lectures, and follow a sample Company database used extensively in the Elmasri textbook.

Company Database Requirements:

1. A normalized set of tables representing employees, projects, departments, dependents and relationships between them.

2. Integrity constraints and validations prevent incorrect data from being entered.

3. Data entry forms using text fields, combo boxes, option groups, etc.

4. A set of standardized reports.

5. A set of standardized queries, which join the information in several tables.

6. Stand alone and LAN capabilities

7. Event driven capabilities on interactive forms using ACCESS macros and BASIC.

8. A customized menu system

9. Custom toolbars

Assignments: There will 12 graded laboratory assignments. The lowest grade will be dropped. Assignments may be handed in up to one week late for a 10 point penalty.

You may work alone or in 2 person teams. Each team member must fully understand the work since many test questions will parallel the assignments. Copying will result in all individuals involved receiving a zero.

Tests: There will be 3 quizzes and a final exam. If all quizzes have been taken the lowest score will be dropped. No quiz makeups.

Grading: Grades will be determined approximately as follows:

Assignments 35%

Quizzes 40%

Final 25%

Attendance: Regular attendance at every class is expected, and anyone who fails to meet this requirement may be requested to withdraw from Wentworth. In addition students with poor attendance may be withdrawn from the class with a grade of "WA". The attendance policies are more fully explained in the Wentworth Catalogue. You are responsible for all material given in class as well as in assigned readings.
