Relational database systems are expected to be equipped with a query language that can assist its users to query the database instances

Relational algebra is procedural query language, which takes Relation as input and generate relation as output. Relational algebra mainly provides theoretical foundation for relational databases and SQL.

Relation Algebra is a widely used procedural query language. It collects instances of relations as input and gives occurrences of relations as output. It uses various operations to perform this action. SQL relation algebra query operations are performed recursively on a relation.

Relation Algebra is a widely used procedural query language. that's why relational algebra used in DBMS

Relational algebra used in DBMS because relational algebra is a theoretical procedural query language that takes an instance of relations and does operations that work on one or more relations to describe another relation without altering the original relation.

The Relational Algebra is very important for several reasons such as:
-It provides a formal foundation for the relational model operations...
-It is used as a basis for implementing and optimizing queries in the query processing and optimization modules that are integral parts of RDBMSs...
-Some of its concepts are incorporated into the SQL standard query language for RDBMSs
