1. The DBA asks for your help in planning the data archive for the following Alexamara database:
Marina (MarinaNum, MarinaName, Address, City, State, Zip)
Owner (OwnerNum, LastName, FirstName, Address, City, State, Zip)
MarinaSlip (SlipID, MarinaNum, SlipNum, Length,
RentalFee, BoatName, BoatType, OwnerNum)
ServiceCategory (CategoryNum, CategoryDescription)
ServiceRequest (ServiceID, SlipID, CategoryNum,
Description, Status, EstHours, SpentHours,
NextServiceDate)
Determine which data from the database to archive; that is, for each table, specify whether data needs to be archived. If it does, specify which data to archive, when it should be archived, and whether it should be archived with data from another table.
2. The DBA denormalized some of the data in the Alexamara database to improve performance, and one of the resulting tables is the following:
MarinaSlip (SlipID, MarinaNum, MarinaName, SlipNum,
Length, RentalFee, BoatName, BoatType, OwnerNum,
LastName, FirstName)
Which field or fields cause the table to no longer be in third normal form? In which normal form is the denormalized table?
3. Interview the DBA at your school or at a local business to determine the security and access privilege procedures used to safeguard data.
