Relation algebra

Relation algebra is a way of representing information from a database. It uses symbols and formulas to represent the information.Think of it like a math equation. A relation algebra equation might look like this:

(A + B) - C = D

This equation means that if you add up two collections of information (A and B) and then subtract another collection of information (C) from the total, you’ll get a result (D). Relation algebra can be used to answer a variety of questions about a database, such as how many items it includes, what items are related to each other, and more.
