Select two tables (not from the textbook) to demonstrate the following queries. (Query 1) - (Query5): Relational Algebra (Query 6) -(Query 7): Relational Calculus (QUERY 1) Build a query consisting SELECT (sigma) operation(s) and show the result set. (QUERY 2) Build a query consisting PROJE (pi) operation(s) and show the result set. (QUERY 3) Build a query consisting union operation and show the result set. (QUERY 4) Build a query consisting intersection operation and show the result set. QUERY 5) Select two tables and build a query consisting division operation. Show the result set. (QUERY 6) Rewrite (Query 1) using Tuple Relational Calculus. (QUERY 7) Rewrite (Query 2) using Domain Relational Calculus
