If the name of the'CS' (Computer Science) Department changes to 'CSSE' (Computer Science and Software Engineering) Department and the corresponding prefix for the course number also changes, identify the columns in the database that would need to be updated. 2. Can you restructure the columns in COURSE, SECTION, and PREREQUISITE tables so that only one column will need to be updated?

Why would the other architectures not be a good choice? [4 points] 2.15 Consider Figure 2.1. In addition to constraints relating the values of columns in one table to columns in another table, there are also constraints that impose restrictions on values in a column or a combination of columns within a table. One such constraint forces that a column or a group of columns must be unique across all rows in the table. For example, in the STUDENT table, the StudentNumber column must be unique (to prevent two different students from having the same StudentNumber). Identify the column or the group of columns in the other tables that must be unique across all rows in the table? Figure 2. Schema dagram for the database in Figure 12.
