What is Relational Algebra Operations Explained about?

Relational algebra is a procedural query language that uses operators to perform queries on databases, producing new relations as output. It includes operations such as selection, projection, union, intersection, difference, Cartesian product, and join, each serving specific purposes in data retrieval. Additionally, relational calculus offers a non-procedural approach to formulating queries, focusing on what results to obtain rather than how to achieve them.
