Question 4. (20 points) Consider the table below where a certain firm is keeping track of temporary worker assignments. This is their only database, they store all relevant information in its single table. Each row corresponds to a single assignment, which is performed by a temporary worker who is identified by "Temp ID" and with name "Temp Name". Each assignment is done for a certain department identified by "Dept Code" and with name "Dept Name", and it consists on doing a certain job identified by "Job Code" and "Job Description". Each assignment also has a "Date", a certain number of hours ("Hours Spent"), and it is paid at a certain rate per hour ("Rate/Hour"). The rate per hour is negotiated separately for each assignment. Your goal is to redesign their single table database Below you have some rows of the table to help you understand the kind of data it stores, and how the data relates with itself.
