Assignment 1: Business Rules and Data Models

A database is an incorporated PC structure that stores end-user information and metadata (Leake, A.). Data is the raw format of information, which when structured properly, it can produce accurate, relevant, and timely information that is the key to making a good database management system. The true purpose of a database is to provide computer-based systems a way in which to store, manage, and retrieve data quickly. A local college has tasked me 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 me to make the database keep track of the instructors teaching each of the courses. The local college database, will be to store the data of enrolled students, the courses offered and class schedule, and the information of the instructors. The database will provide course matches for each student based off previous courses taken and pre-requisites obtained, as well as keep track of the instructors that are teaching the class. The database will provide the data a student needs to insure they are taking the correct courses and provide the college and the faculty general student information, such as student ID. Entities (Tables) are defined as a person, place, thing, or event in which data is collected and stored. Each entity is a unique object that may be a physical or abstract object within real life (for example: Student Name) (Jones, D.). Entities of a database for a college that needs to keep track of students and courses would be students, Instructor, courses, classes, room, class schedule and enrollment status. Attributes are characteristics of an entity, such as a name, phone number, or address. Attributes(Records) for the college database would include student first and last name, student phone
