Relational database implementation, Database Management System

Assignment Help:

You must implement the entity relationship model provided in the model solution to Assignment 1. The model solution will be released on the course website approximately TWO (2) weeks after the Assignment 1 due date.

The recommended tool for this assignment is Microsoft Access, version 2000 or later. One reason for recommending Microsoft Access is that your course lecturer will be able to provide support in the use of this tool. If you choose to use a different DBMS, then there is no guarantee that your lecturer will be able to provide support. Note: If you choose not to use Microsoft Access, you must contact your lead lecturer as soon as possible before you start work on the assignment. The remainder of this document assumes you are using Access.

In implementing the ERD provided, you must complete the following tasks:

• Map the ERD into a set of relations in at least Third Normal Form (3NF). You must ensure that your relations meet 3NF. There is no need to show your working.
• Select any two (2) of your relations from the previous step and for each of them:
• List all the functional dependencies present in the relation
• Demonstrate that the relation meets Third Normal Form (3NF), for example:

STUDENT (StudentID, Name, Address, DateOfBirth)

The primary key is StudentID; this is the only candidate key since Name is not guaranteed to be unique (two different students may have the same name). Address is also not guaranteed to be unique. There will be one student name per Student ID, since only one name is recorded for each student. There will be one address per Student ID; even though a student may have multiple addresses (e.g. a home address and a work address), the case study states that there is only a need to record the home address. There will be only one date of birth per Student ID. This means that Student ID functionally determines every other attribute in the table; therefore there are no repeating groups. There is a single simple candidate key, therefore no partial dependencies are possible. Name cannot be used to functionally determine any other attribute in the table since two different students may have the same name; likewise for address and date of birth, therefore there are no transitive dependencies in the table. Therefore it meets the requirements of first, second and third normal form.

• Create all the relations in a Microsoft Access database. Consider each attribute in every table and make appropriate choices regarding data types and sizes, indexes, required/not required, and validation rules. Your choices should be appropriate for each attribute and should support data integrity. (Note: see the Data Integrity section below for specific data integrity requirements.)

• Create relationships as appropriate. Enforce referential integrity for all appropriate relationships in the database. Explore the possibility of cascade update and/or delete options.

• Review the default indexes created by Access for each table. You should ensure that the indexes follow the guidelines given on page 284-285 of the set text.

• Populate the database with sample data. You must include sufficient sample data to test your queries and report. You should aim for at least 5 or 6 rows in every table.
