A Critical Study on Idempotent Matrices and Its Significance |

ABSTRACT:

Looking up some customer's name and address in a database aretypically idempotent (in fact nullipotent),since this will not cause the database to change. Similarly, changing acustomer's address is typically idempotent, because the final address will bethe same no matter how many times it is submitted. However, placing an orderfor a car for the customer is typically not idempotent, since running themethod/call several times will lead to several orders being placed. Cancelingan order is idempotent, because the order remains canceled no matter how manyrequests are made.
