Question:
- Write five questions that can be answered from the data in your database (read the query code requirements).
- Write query code to find answers to your questions. Your code must include the following:
- At least one union (justify why this was needed over a join).
- At least two joins. Provide an explanation of which type of join you used and why it was the best option.
Even if you aren't building or maintaining databases in your job, you might still have to query them. This assignment will provide practice finding answers from your data. Be sure to review the Unit 6 Toolbox for an explanation of concepts.
