Relational Algebra is a procedural query language that provides a set of operations to manipulate and retrieve data from relational databases.
- It works with relations (tables) and applies various operations to return a new relation as a result.
Relational Calculus is a non-procedural query language that focuses on what to retrieve rather than how to retrieve it.
- It specifies conditions that the result must satisfy without describing the specific steps to obtain the result.
