Abstract

In the current research, we introduce two operations of a “symmetric difference” type over three-dimensional extended index matrices, and investigate some of their basic properties. An example of the implementation of symmetric difference-type operations is presented in the field of relational databases, aiming to demonstrate the operations’ efficiency by comparing sets with dissimilar attributes.
