INTRODUCTION
UML stands for unified modelling language that standardized language which mainly
consists of an integrated set of diagram. In order to develop the system and developers for

users and different use cases. In above figure: 1, it has been represented the use diagram where
system, system and employee are performing the different action for exchanging data between
them. It is way to establish the relationship between them (Dadeau, Fourneret and
Bouchelaghem, 2019).
By using use case diagram, it is mainly understanding the behavior through diagrams and
describe to set of action that some system. It should be collaboration with one or more external
