I’m working on a Computer Science question and need guidance to help me study.
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 PROJECT (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.
