Consider the data about students in your university's database as a huge table containing a row for each student and a column for each data element. Sort the data into main categories such as contact information, medical information, financial information, and academic information. Which employment categories should be accessible to which groups of people? Who should have access to a single row within a group, who should have access to multiple rows but not to all rows, and who should have access to all rows in the table? Should anyone have the ability to view data but not alter it?
