Don't forget to specify appropriate primary and foreign keys when you do so! You are welcome to pick data types of your own choice.For each table, include a justification of why you picked each data type, and any other decisions taken. (This is worth 30 points).2) Next, insert the data you see here into each of the tables created in step 1) using INSERT statements.Remember, not your own data, but the data that i've presented above. (This is worth 30 points).3) create appropriate SQL queries to answer the following questions.(16 points per question for a total of 96 points + 4 points for cleanness of presentation = 100 points).For each department, list department number, department name and number of employees in these departmentsList department number, department name, and number of employees in departments that have two or more employees, ordered by department number. List employee names (first_name and last_name) of each male employee, together with their department name.List the distinct name of employees who are not working in "Research"List the name and number of departments whose employee average salary is between 30000 and 60000.List the name of employees who works (department location) in Salt Lake City and whose last name start with 'D'.4) This question consists of four parts, and is worth 40 points. Please note that you need to work on this individually even if you are working as part of a group.

As an example, lets say that my organization is a bank.Imagine that your organization already has the three tables that we just created. List three additional tables that would be of use to your organization, and provide a rationale.Write create statements for your table using SQL. The better your SQL and design, the better your grade!Identify one logical question that you would be able to answer for your organization if you had these new tables populated with data. In this case, i'm not looking for SQL, but rather, a meaningful question that you could answer using queries on the new tables. Please note that the questions need to be as objective and specific as possible!Save the file as a pdf or word doc,
