CIS 111 Week 2 Assignment 1 Business Rules and Data Models Updated

Assignment 1: Business Rules and Data Models

Suppose a local college has tasked you to develop a database that will keep track of students and the courses that they have taken. In addition to tracking the students and courses, the client wants the database to keep track of the instructors teaching each of the courses.

Use the internet to research the types of information that a college would want to track in a database. Focus your attention on information that could represent entities within a database as well as attributes of such entities.

Write a two to three (2-3) page paper in which you:

1. Describe the purpose of the database.

2. Based on your research and / or common knowledge of a college and the information tracked by a college, describe the entities of the database and the attributes of each entity.

3. Based on your research and / or common knowledge of a college and the information tracked by a college, describe the business rules that could impact the structure of the database.

4. Determine the information that the conceptual model of the database would include and determine the information that the physical model of the database would include.

Your assignment must follow these formatting requirements:

• Be typed, double spaced, using Times New Roman font (size 12), with one-inch margins on all sides; citations and references must follow APA or school-specific format. Check with your professor for any additional instructions.

• Include a cover page containing the title of the assignment, the student’s name, the professor’s name, the course title, and the date. The cover page and the reference page are not included in the required assignment page length.

The specific course learning outcomes associated with this assignment are:

• Describe the role of databases and database management systems in managing organizational data and information.

• Compose conceptual data modeling techniques to capture the information requirements.

• Use technology and information resources to research issues in database systems.

• Write clearly and concisely about relational database management systems using proper writing mechanics and technical style conventions.

(Note: This tutorial focuses on the use of Microsoft Visio. Open source applications are not covered in Appendix A. However, the use of open source applications within labs is permitted.)

After reviewing your database design from Lab 1: Creating a Database Design in Visio, the college has provided more information for the database that they want developed:

• For each student, the college needs to track the student ID, student names, addresses, start date, phone numbers and types (such as mobile, home, work), email addresses and types (such as personal, school, work), gender, and birth date.

• For each course, the college needs to track the course ID, course name, department, quarters offered, sections, and instructor teaching each course.

• For each instructor, the college needs to track the instructor ID, name, address, phone numbers and types (such as mobile, home, work), email addresses and types (such as personal, school, work), gender, birth date, and the courses that each instructor is qualified to teach.

• Additionally, the college needs to track the final grades for each student after each course has completed.

Section 1: Modified Visio Diagram

(Microsoft Visio or equivalent)

1. Use Microsoft Visio (or open source equivalent) in which you:

1. Modify the database diagram from Lab 1 with the entities and attributes that the scenario identified (i.e., a college tracking students, courses, and instructors).
