Designing Object Oriented Models through UML diagrams for Hotel Front Office System

Abstract

Design patterns are recurring solutions to software design problems you find again and again in real-world application development. Patterns are about design and interaction of objects, as well as providing a communication platform concerning elegant, reusable solutions to commonly encountered programming challenges. The proposed system deals with the object-oriented design model through Unified Modeling Language (UML) for a Front Office process of the Hotel. The FO process includes Room reservation, Check-in, accumulation of expense during the guest stay, Check out and Management reports. This system implements with the five design pattern classes. UML diagrams of Adapter, Singleton, Proxy, Visitor, Observer design patterns are used to build object-oriented models for developing the Hotel FO system. The designed objects are implemented to classes using C#.NET programming language.
