Based on the below tables (Entity-Relationship Model), develop a Structured Query Language using MySQL for Walmart that contains the following items:

 

1. Provide the scripts needed to create the above tables.

a. Data Manipulation (DML) Scripts:

• Insert at least 10 records into each table.
• Delete a record from any table using its unique identifier (primary key) field.
• Update a record in any table using its unique identifier (primary key) field.
• Add 2 to 3 of your own DML scripts to manipulate data in your database.

2. Include scripts with the following queries for reporting:

• Total number of orders by customer.
• Total number of orders by product.
• Provide 2 to 3 aggregate function scripts to show use of AVG, MAX, MIN, COUNT or SUM.

3. Give a narrative of how this design fulfills the mission and goals of Walmart.
