Introduction

The objective of this assignment is to demonstrate proficiency in relational database management using MySQL, specifically focusing on creating tables and relationships based on a predefined database design, populating those tables with data, executing specific queries, and documenting the process with visual evidence. This task is rooted in a prior lab exercise (Lab 2) that involved designing a database schema, which students now extend by implementing and querying within MySQL.

Design and Creation of Tables and Relationships

Based on the database schema discussed in Lab 2, the first step involves creating the tables and establishing relationships. Typical tables in such a database include Students, Instructors, and Courses. The definitions of these tables need to include appropriate primary keys and foreign keys to enforce referential integrity and relationships.

For example, the Students table might include student_id (primary key), first_name, last_name, phone_number, and other relevant attributes. The Instructors table might comprise instructor_id, first_name, last_name, and contact info. The Courses table would likely have course_id, course_name, and instructor_id as a foreign key pointing to the Instructors table.

After defining the schema, the next step involves executing the CREATE TABLE statements in MySQL to instantiate these tables, followed by adding at least five records to each table. The data values should be realistic but can be arbitrary, ensuring each record is unique and valid, particularly respecting data types and constraints.

Populating Data

Insert five records into each of the created tables. For example, in the students table, insert students with varying first and last names, phone numbers, and other relevant details. Instructors and courses tables should similarly contain diverse entries, with course records linked to instructors via foreign keys. Properly structured INSERT statements are used for this purpose.

This step lays the groundwork for meaningful queries and demonstrates data integrity and relationships among tables.

Querying the Data

The next steps involve creating SQL queries to retrieve specific information:

• A query that retrieves all fields from the students table where the student's last name is "Smith".
• A query that displays students’ first names, last names, and phone numbers.
• A query that lists instructors' first names, last names, and the courses they teach.

These queries utilize SELECT statements with WHERE clauses and JOIN operations to combine data from multiple tables when necessary, especially for the instructors and courses query if they are stored separately.

Documentation with Screenshots

Throughout the process, screenshots must be captured to document each step:

1. Table creation in MySQL showing table schemas.
2. Inserted records into each table, showing the data entries.
3. SQL code used for each query and the output/results of those queries.

These screenshots should be compiled into a Microsoft Word document, providing visual evidence of work completed and facilitating verification of every step.

Conclusion

In conclusion, this assignment reinforces key database skills in table creation, data population, and querying within MySQL. Proper documentation through screenshots enhances understanding and provides clarity on the workflow, which is essential for database management and reporting.
