The most important characteristic of an entity is its primary key, used to uniquely identify each entity instance.

<h3>What is primary key?</h3>

A column, or group of columns, known as a primary key in a table uniquely identifies each row of data. For instance, CustomerNo, which displays the ID numbers assigned to individual customers.

The primary key of a relational database, often called the primary keyword, is a key that is unique to each entry. It is a unique identification number, much like the ones on a driver's license, phone with an area code, or car (VIN). A relational database's primary key must always be distinct.

JulijaS [17]

In interdependence theory, the term <u>rewards </u>refers to anything within an interaction that is desirable and welcome and that brings enjoyment or fulfillment to the recipient.

Costs, on the other hand, are painful, unpleasant experiences.

According to the interdependent theory, people frequently show generosity to those who they depend on in the pursuit of positive outcomes since doing so is rational (and worthwhile).

According to the social exchange theory known as interpersonal interdependence, which is described as "the process through which interacting people impact one another's experiences," interpersonal relationships are defined through this process.

The Social Psychology of Groups, written in 1959 by Harold Kelley and John Thibaut, contained the first publication of interdependence theory.

This book presented crucial definitions and concepts crucial to the creation of the interdependence framework, drawing inspiration from social exchange theory and game theory. Specifically, Interpersonal Relations, their second work.
