This chapter describes the Cartesian products of sets, relations, and functions as relations. The set of all ordered pairs (x, y) such that x ∈ X and y ∈ Y is called the Cartesian product of the sets X and Y and is denoted by X × Y. Cartesian products of sets occur very often...
Noun1.Cartesian product- the set of elements common to two or more sets; "the set of red hats is the intersection of the set of hats and the set of red things" intersection,product set- a group of things of the same kind that belong together and are so used; "a set of books"; ...
Cartesian product finds its uses in many real-life objects such as a deck of cards, chess boards, computer images, etc. The digital images that we see on our computers and mobile phones are represented as pixels which are graphical representations of cartesian products. In mathematics, the cart...

cartesian products of sets properties some of the important properties of cartesian products of sets are given below. (i) two ordered pairs are equal, if and only if the corresponding first elements are equal and the second elements are also equal. (ii) if there are m elements in a and ...
Luckily, we canusuallyavoid cartesian products through careful aggregate design. Still, sometimes we truly do want to join multiple 1:N relations. Of course, we would rather not risk a huge data set caused by an incidental high number of child entities. ...
Summary: Sesquicartesian categories are categories with nonempty finite products and arbitrary finite sums, including the empty sum. Coherence is here demonstrated for sesquicartesian categories in which the first and the second projection from the product of the initial object with itself are the same...
