3. Using these data presented in the list, state assumptions about functional dependencies among the columns of data. Justify your assumptions on the basis of these sample data and also on the basis of what you know about service businesses. Indicate what assumptions need to be checked with the users (GG) and what suggestions you may have about the determinants/keys (e.g., do you need a surrogate key?)
4. Based on the above analysis and assumptions, split the sample list into tables such that each has only one theme. Demonstrate that the modification problems you identified in E have been eliminated.
5.Assume that based on your suggestions and their additional requirements, Garden Glory designs a trail database saved as Garden_Glory.accdb in MS Access 2013. Query the trail database using SQL statements and answer the following questions. For each SQL statement you write, show the results based on your data (you could press the "PrtSc - Print Screen" key to capture the results image) .
5.1) Write SQL statements to list all columns for all tables.
5.2) Write an SQL statement to list the LastName , FirstName and CellPhone for all employees having an experience level of Master .
5.3) Write an SQL statement to list the LastName , FirstName and CellPhone for all employees having an experience level of Master and a FirstName that begins with the letter J .
5.4) Write an SQL statement to list the Name of employees who have worked on a property in New York .
5.5) Write an SQL statement to list the names of employees who have worked on a property owned by a Corporation .
5.6) Write an SQL statement to show the name and sum of HoursWorked for each employee.
5.7) Write an SQL statement to show the sum of HoursWorked for each ExperienceLevel of EMPLOYEE. Sort the results by ExperienceLevel in descending order.
