The conceptual idea is, Null and Empty are different. for exmaple consider "telephone_number" is a variable i have to assign the value. if its EMPTY means, i didnot asked the person for "telephone_number" so its EMPTY now, means value is not collected. Suppose that i asked the person about his "telephone_number" if he dont have any telephone means i can assign NULL to the "telephone_number".
