Question

How can the \(4 - \)ary relation containing names of students, their addresses, telephone numbers, majors and the \(4 - \)ary relation containing names of students, their student numbers, majors and numbers of credit hours be combined into a single \(n - \) ary relation?

Short answer

We can multiply both the ary and we get the result.

Step-by-step solution

Given data

The \(4 - \)ary relation containing names of students, their addresses, telephone numbers, majors and the \(4 - \)ary relation containing names of students, their student numbers.

Concept used of set and subset

Set - A collection of objects. The specific objects within the set are called the elements or members of the set

Set\(A\)is said to be a subset of Set\(B\)if all the elements of Set\(A\)are also present in Set\(B\). In other words, set\(A\)is contained inside Set\(B\).

Define relation

It is possible as \(n\) - ary is the subset of the product of the given sets. We can multiply both the ary and we get the result.
