The correct answer is E. query.
A query is a small program that can perform advanced operations on a database. It allows users to retrieve and manipulate data from one or more tables, making the database more powerful and user-friendly. Queries can be used to search for specific information, calculate values, create new tables, and more.
For example, let's say you have a database of student records with different fields such as name, age, and grade. You can use a query to search for all students who are above a certain age or calculate the average grade of all students. By using queries, you can quickly and efficiently extract the information you need from the database.
