A set is not an operation.
The main operations of relational algebra are 1. The select Operation 2. The projection operation 3. The union operation 4.The set different operations 5.The Cartesian-product operation. 6.The rename operation. 7.Additional operations. 8.The Set-Intersection operations. 9.Natural-join operations. 10.Division operation. 11.The Assignment operation.
Relational set operators in dbms uses algebra to manipulates contents in a data base. there are many different operation in Dbms ,they are :- 1.Union 2.intersect 3.Product 4.select 5.Project 6.divide
operation set
operation set
A set is a set and does not need an arithmetic operation.
The law of closure states that a set of numbers is closed under an operation if when the operation is performed on any two elements of the set the result is an element of the set
what happens when pollution alarm set point reached during operation
natural number
A set of number with a defined operation (e.g. addition, multiplication etc.), such that the outcome of the operation between any two numbers is also a member ot the set.
The main set operations are: union, intersection and complement.
In Set Theory: a set is closed under an operation if performance of that operation on members of the set always produces a member of the same set.In Topology: a closed set is a set which contains all its limit points.
