In this example, we will pretend that the student table in the university database is indexed by StudentID (the primary key), Major, Age, MaritalStatus, and HomeZipCode (all secondary keys). Let's pretend a university needed a list of students from the 45462 zip code who are either above the age of 25, married, and majoring in MIS or computer science OR who are under the age of 25 and majoring in computer engineering. Is there a way to use indexes to restrict results to to those entries that fulfill this condition?

Refer to the film and inventory tables of the Sakila database. The tables in this lab have the same columns and data types but fewer rows.

. Let's say that this restaurant only takes customers if they made a reservation, and each reservation is used to represent a party of people. Add a table to the database containing each individual food item that was ordered by a party of people. Hint: you will want to use two columns as the primary key for this table. This table should represent each food item that was ordered by a party of people. You may create a third column in this table called 'quantity', so we know how much of a food item a party of people ordered. *Enter 3-4 test records of data for each table. . Design the database tables for the scenario described above. Think of some possible attributes for each table. . Write "PK" above each column that is a Primary Key and "FK" above each column that is a Foreign Key. ●
