What is Relational Algebra Basics Explained about?

This document introduces relational algebra, which provides operators to retrieve data from relations. The core operators include set operations like union and intersection, renaming attributes, and selecting or projecting tuples to decompose relations horizontally and vertically. Relational algebra draws analogies to arithmetic algebra by treating relations as sets that can be combined using defined operators to express queries and derive equivalent expressions.
