ABSTRACT
Today’s hotel management refers to the professional hospitality sector rendered by host continents. This can include administrator, accounted, marketing and room keeper, beverage management catering and maintenance of hotel. Many Hotel Loyalty Programs can be used to entice guests into becoming a regular guest at the hotel. These programs are especially beneficial to hotel chains, where the benefits of the program can span over their entire hotel chains. The proposed modeling methodology is based on the principle of object identification and aspect discovery, which allows explicit description of software functionalities. Furthermore, it is illustrated how the well-known object-oriented specification language unified modeling language can be adopted, to provided an adequate formalization of its semantics, to describe structural and behavioral aspects of hotel database management system related to both rational and physical parts. It is a proven fact that flaw in modeling process can substantially contribute to the development cost and time and the operational efficiency may be affected as well. Hence attention is focused on developing the models so as to obtain a clear vision and understanding of the implementation aspects of the same and the knowledge of integration with recent emergent technologies.
INTRODUCTION
The Unified Modeling Language (UML) is a standard visual modeling language intended to be used for modeling the business and similar processes and analysis, design, and implementation of software-based systems. UML is appropriate for both new system developments and improvements to existing systems that can be implemented in UML pad. It is a fallacy that in order to use a new modeling technique on an old system, the old system will have to be completely re-documented in the new style in order for any change to take place. The designing in software engineering lifecycle has been developed for a software product can have a large impact on the maintenance of the product.
USE CASE DIAGRAM
First and most importantly, I will define what a use case is. A use case is a tactic used in system analysis to identify, clarify, and categorize system requirements. This is the simplest way to understand what use cases are in software engineering and what they do. Actors could be anybody from persons who are the users of the system to organizations and computer systems too. The use case is made up of a set of possible sequences of interactions between systems and users within an environment and related to a particular goal. The use case should contain all system activities that have significance to the users within a given system. They are basically initiators of the system.
ACTIVITY DIAGRAM
Activity diagrams are typically used for business
process modelling.It is used for modeling the logic
captured by a single use case , or for modeling the
detailed logic of a business process where it can be
implemented in an efficient manner. Activity diagram
is also used to describe the dynamic aspects of the
system. Activity diagram is basically a flow chart to
represent the flow form one activity to another
activity. The activity can be described as an operation
of the system. Activity diagrams deals with all type of
flow control by using different elements like fork, join
etc. The activity diagram is very suitable for modeling
the activity flow of the system where they can have
multiple systems. Activity diagram also captures these
systems and describes flow from one system to
another. This specific usage is not available in other
diagrams. These systems can be database, external
queues or any other system.
CONCLUSION AND FUTURE
WORK
The paper has focused on the essential and extended
Object Oriented features of a Hotel Management
System. Various models of UML have been employed
to analyze the static, dynamic and functional view of
the system. In spite of several user-friendly, timesaving,
cost-effective, convenient and flexible options
provided by banks in the virtual space, Hotel
Management System has not achieved a major breakthrough
that it deserves. However if an Object
Oriented approach is adopted while building the
software, an explosive growth in Hotel Management
System arena could be traced. As part of future work
we have planned to implement the same with Java as
front end and any reliable online database system such
as MySQL, as back end, and Rational Test Manager
could be employed for testing. We also focus on
integrating high end modern technologies such as iris
recognition and modern finger print authentication
system to be integrated with the implemented system
so as to provide secured confidentiality of the
customers.
