Difference between cartesian product and full outer join?
Full outer join will fetch at maximum 'addition of 2 tables' Ex: Table A - 2 rows; Table B - 3 rows. Full outer join will fetch in 2+3 = 5 rows. Where as in Cartesian product will fetch in 'product of 2 tables'. Ex: Table A - 2 rows; Table B - 3 rows. Full outer join will fetch in 2x3 = 6 rows
What is difference between Cartesian product and natural Join Operation?
Difference Between CARTESIAN PRODUCT & NATURAL JOINT Cartesian product is like the cross product ie every element of one row of one table/entity is multiplied to every column of another table for solving linked queries of two tables ... Where as natural Join is simply joining two or more entities eliminating the common attributes or columns.. @nayan answered it :)

Is the product of any two irrational numbers is an irrational?
No. The product of sqrt(2) and sqrt(2) is 2, a rational number. Consider surds of the form a+sqrt(b) where a and b are rational but sqrt(b) is irrational. The surd has a conjugate pair which is a - sqrt(b). Both these are irrational, but their product is a2 - b, which is rational.
Which Expression represents the product of a number 5 and b?
The product of '5' and 'b' is '5b' Product is another word for multiplication. '5b' means '5' multiplied to 'b' NB The multiplication sign is never shown in algebra. NNB The number/coefficient always comes before the letter.
Cartesian product of sets A and B is finite then does it follow that A and B are finite?
The number of elements in a Cartesian product is equal to the product in the number of elements of each set. The idea of a Cartesian product is that you combine each element from set A with each element from set B. If the product set (the Cartesian product) of sets A and B has a finite number of elements, this may be due to the fact that both A and B are finite. However, there is another possibility: that one of the sets, for example, set A, has zero elements, and the other is infinite. In this case, the Cartesian product would also have zero elements.
A set of ordered pairs is called?
Cartesian product is the name that refers to the set of the ordered pairs. The Cartesian product of two sets A and B is AB.
What is the Cartesian product?
A Cartesian product of two sets is a set that contains all ordered pairs, such that the first item is from the first set and the second item from the second set. (It can be the same set twice, instead of two different sets.) For example, the Cartesian product of the sets {A, B} and {1, 2, 3} is the set of pairs: {(A, 1), (A, 2), (A, 3), (B, 1), (B, 2), (B, 3)} In general, the Cartesian product has a number of elements that is the product of the number of elements of the two products that make it up. A Cartesian product can also be defined for more than two sets. Cartesian products are very important as the basis of mathematics. For example, relations are subsets of Cartesian products. Note that functions are a special type of relation.
What is the magnitude of cartesian product?
The Cartesian product of two sets, A and B, where A has m distinct elements and B has n, is the set of m*n ordered pairs. The magnitude is, therefore m*n.
What is the Cartesian product of two sets?
If S and T are any two sets, then their Cartesian product, written S X T, is the set of all of the ordered pairs {s, t} such that s Є Sand t Є T.For some basic set theory, follow the related link.Also, the Cartesian product is used in the definition of "relation" and "metric." Follow the corresponding links for more information.
What are the set of operation?
operation set
What is the set of all ordered pairs?
It is the set of all ordered pairs - nothing less, nothing more.The set may be represented by the coordinates of all points on a plane. But the coordinate plane is not the set.This result is a so-called product set and is called a Cartesian product.
Difference between cartesian product and full outer join?
Full outer join will fetch at maximum 'addition of 2 tables' Ex: Table A - 2 rows; Table B - 3 rows. Full outer join will fetch in 2+3 = 5 rows. Where as in Cartesian product will fetch in 'product of 2 tables'. Ex: Table A - 2 rows; Table B - 3 rows. Full outer join will fetch in 2x3 = 6 rows
What can be graphed as a point or set of points?
Cartesian coordinate system
How is a relation between two sets defined?
A relation between two sets is defined to be any subset of the two set's Cartesian product. See related links for more information and an example.

What are the four operations of sets?
The four basic operations of sets are unions, intersections, complements, and the Cartesian product.UnionsA union is essentially the act of 'adding' multiple sets together to combine their elements into a single set.example: if A={1,3,5} and B={2,4,6} then the union A∪B={1,2,3,4,5,6} however, the same elements are not counted twice so if A={1,2,5} and B={1,2,4} then A∪B={1,2,4,5}IntersectionsAn intersection makes a new set from the common elements of the sets involved.example: for A={2,3,5,7,11}, B={2,5,8} and C={5,9,11} then the intersection A∩(B∩C)={5}Notice that even though A and B have 2, and A and C have 11, the intersection of the three sets is 5 as that is the only common element between all three.Also notice that if you take the intersection of two sets with no elements in common you end up with the empty set.ComplementsThere are 2 complements, the relative complement and the absolute complement.The relative complement is the 'subtraction' of multiple sets. The relative complement of A in B, written B\A, is the set of all elements that are in B but aren't in A.example: A={1,2,3,4,5,6}, B={5,6,7,8,9} then B\A={7,8,9}This property does not commute, B\A≠A\BGiven a universal set U, defined as containing all the elements in that area, the absolute complement is the complement of A in U, and is denoted as Ac. i.e. Ac is the set of all elements in U that aren't in A.example: let U={1,2,3,4,5,6,7,8,9,10}, and A={2,3,5,7}. Then Ac={1,4,6,8,9,10}bigger example: if U={x∈ℕ} (the set of all positive integers not including 0) and A={x=2k|k∈ℕ} (the set off all positive and even numbers) then Ac is the set of all positive and odd integers.Cartesian ProductThe cartesian product is the combination of elements from multiple sets.example: Let A={1,2,3} and B={red, blue} then the Cartesian product AxB={(1,red), (1,blue), (2,red), (2,blue), (3,red), (3,blue)}This property generally does not commute, AxB=BxA if and only if A=B.
