INTRODUCTION
Object oriented programming can be defined as the programming paradigm which
is based on the conceptions of objects which consists code in the form of procedures also known
as methods and data in the form of fields also known as attributes and properties. Its features
includes that its objects owns procedures which can access and alter the data field of itself
(Kanaki and Kalogiannakis, 2018). Here the scenario is to develop the system of online booking
for birthday party club which includes the necessary requirements such as the log in, log out,
payments, reservations, availability and many more as per the needs of the club management.
Therefore, the following discussion is made on the use case diagram, domain model, sequence
diagram and class diagram in context of the online booking system of birthday party club for
effective, efficient and potential management of the club with proper findings and conclusion.
MAIN BODY
Create a Use Case for the new Online Booking System
Use case diagram can be defined as the representation of the of the user's communication
or interaction with the system which depicts the relationship between the user and various cases
in which they are involved with the system (Elallaoui, Nafil and Touahni, 2018). Here the use
case diagram is of online booking system of birthday party club in which the actors are the
manager and the customers who are are responsible to operate the system in which managers will
handle database server side of the system and user will operate front end side of the system. Use
cases involved in such situation are log in to the program, customer's information, accepts and
confirms reservations, check in customers, income statement, check out customers and computes
customer bill. Some use cases are only for the managers or administrators of the club and some
are for the customers specific. They are labelled by three tags such as uses, initiates and depends
which means that uses are considered as all the uses combined for the managers and customers.
Initiates are considered as the uses which are used by both the parties that is the managers as well
as the customers and depends are considered as the extend function which expands the function
further more for the managers and customers also.
