ABSTRACT FACTORY AND SINGLETON DESIGN PATTERNS TO CREATE DECORATOR PATTERN OBJECTS IN WEB APPLICATION

Software Design Patterns are reusable designs providing common solutions to the similar kind of problems in software development. Creational patterns are that category of design patterns which aid in how objects are created, composed and represented. They abstract the creation of objects from clients thus making the application more adaptable to future requirements changes. In this work, it has been proposed and implemented the creation of objects involved in Decorator Design Pattern. (Decorator Pattern Adds Additional responsibilities to the individual objects dynamically and transparently without affecting other objects). This enhanced the reusability of the application design, made application more adaptable to future requirement changes and eased the system maintenance. Proposed DMS (Development Management System) web application is implemented using .NET framework, ASP.NET and C#.
