Using any RDBMS preferably (MySQL), create the physical data model for the logical data model provided in the attachment. This should include all of the data definition language SQL. This should be based upon the previous ERD created (see figure below) for the final solution of an RDBMS.   Provide justification for the RDBMS you chose and created.

As you are designing and developing the database, you think to the future and want to be able to grow the database as required, not only expanding the data model as needed, but also in the event that the company wants to open remote data centers and have replicated copies of the data. Describe distributed databases and how they might be used.

Include all DDL needed to:

  • Create the tables
  • Create the primary keys
  • Create the foreign keys
  • Add DML statements with discussion / explanation to:
    • Add data of 1 customer who buys from the company
    • Provide the DML to add 1 employee who interacts with customers
    • Give DML to change data of the employee, giving the commission a 25% increase
    • Give DML to delete the customer and employee data
  • Write 3 SELECT statements with discussion / explanation
    • To select the customer details
    • To select the employees details
    • To show which employee services which customer

The solution should contain the following:

  • Screenshot of the ERD, logical (updated/modified from attachment)
  • The DDL to create the tables, including the table definition and the primary and foreign key definitions.
  • SQL to add data to the tables
    • Add data of 1 customer who buys from the company
    • Provide the DML to add 1 employee who interacts with customers
    • Give DML to change data of the employee, giving the commission a 25% increase
    • Give DML to delete the customer and employee data
  • Write 3 SELECT statements:
    • To select the customer details
    • To select the employees details
    • To show which employee services which customer
