It is a query system where queries are expressed as variables and formulas on these variables. It is a non-procedural or declarative by nature. In this, the formulas describe the properties of the required result relation without describing how to compute it i.e., query represents only results and hides the procedure to find the result. Relational calculus is based on predicate calculus, which is used to symbolize logical arguments in mathematics. Relational calculus has two variants. The first one is called Tuple Relational Calculus in which variables take on tuples as values. The second one is called Domain Relational Calculus in which variables range over the underlying domains. Relational Calculus has strongly influenced the design of many query languages like SQL and QBE. 4.1- What Is Relational Algebra | Relational Algebra In DBMS | Relational Operators In DBMS    • 4.1- What Is Relational Algebra In dbms in...   4.2- Relational Operations In Relational Algebra | Relational Algebra- relational database operators    • 4.2- Relational Operations In Relational A...   4.9- Cartesian Product Operation In Relational Algebra | Relational Algebra In DBMS | DBMS Course    • 4.9- Cartesian Product Operation In Relati...   4.10- Division Operation In Relational Algebra In DBMS | Relational Algebra In DBMS | DBMS Course    • 4.10- Division Operation In Relational Alg...   4.11- Join Operation In Relational Algebra In DBMS | Relational Algebra In DBMS | DBMS Course    • 4.11- Join Operation In Relational Algebra...   4.12- Inner Join Theta And Equi Join Operation In Relational Algebra In DBMS | Relational Algebra    • 4.12- Inner Join Theta And Equi Join Opera...   4.13- Inner Join - Natural Join Operation In Relational Algebra In DBMS | Relational Algebra | DBMS    • 4.13- Inner Join - Natural Join Operation ...   4.14- Left Outer Join Operation In Relational Algebra In DBMS | Relational Algebra In DBMS    • 4.14- Left Outer Join Operation In Relatio...   4.15- Right Outer Join Operation In Relational Algebra In DBMS | Relational Algebra In DBMS    • 4.15- Right Outer Join Operation In Relati...   4.16- Full Outer Join Operation In Relational Algebra In DBMS | Relational Algebra In DBMS | Join    • 4.16- Full Outer Join Operation In Relatio...   Notes Link: http://www.tutorialsspace.com/Downloa...
