SQL Script To Create The Premiere Database And Associated Ta

SQL script to create the PREMIERE database and associated tables and then load the data

This assignment requires creating a database named PREMIERE using MySQL, along with several tables: rep, customer, orders, part, and order_line. The process includes defining the structure of each table, establishing primary keys and foreign key relationships to maintain referential integrity, and then populating each table with the provided data. The dataset includes representatives, customers, orders, parts, and order line details relevant to a retail or wholesale context. The structured approach begins with creating the database and switching to it, followed by table creation, setting appropriate data types, and inserting data entries into each table to reflect realistic business data, enabling complex querying and analysis.

The process of designing and populating a relational database in MySQL begins with defining a suitable schema to store the necessary information about representatives, customers, orders, parts, and order details. This comprehensive approach ensures data consistency, efficiency, and the ability to generate meaningful reports and insights. The first step involves creating the database named PREMIERE, which serves as a container for all related tables and data.

Following database creation, each table is carefully constructed with appropriate columns, data types, and constraints. The rep table captures data about sales representatives, including their number, name, address, commission, and rate, with rep_num as the primary key. The customer table stores customer information—including their unique number, name, address, credit details, and an associated sales representative—linked via a foreign key to the rep table. This relational link maintains referential integrity between customers and their reps.

The orders table records purchase transactions, with each order linked to a customer through a foreign key. The part table holds details of inventory items, including description, stock on hand, classification, warehouse location, and unit price, with part_num as the primary key. The order_line table details the specific parts included in each order, recording the quantity ordered and quoted price, with composite primary key comprising order_num and part_num. This setup allows capturing multiple items per order, along with their associated transaction details.

Once the schema is established, the next phase involves populating the tables with the provided data. Data insertion includes sample representatives like Valerie Kaiser, Richard Hull, and Juan Perez, with their addresses and commission rates. Customers such as Al's Appliance, Brookings Direct, and Ferguson's are linked to these representatives. Orders are created with references to customers but without specific dates (left blank in sample). The inventory includes parts like iron, home gym, microwave oven, and treadmill, with quantities and prices. Order lines reflect actual purchase quantities and quoted prices, providing transaction details essential for reporting and analysis.

This database enables handling typical retail operations, including tracking sales performance, inventory stock levels, and customer transactions. The relationships between tables support complex queries such as identifying top-performing representatives, monitoring customer balances, analyzing sales by product or location, and more. The initial setup with integrity constraints ensures data consistency, while the extensive data entries allow testing various real-world business scenarios within the MySQL environment.
