Framework development using design patterns

Creating and maintaning a product of good quality quickly is one of the main goals of the engineering applications. This goal is also examined in software engineering concepts. Using software frameworks, which provide the basic components for the software applications of the same domain, helps in creating and maintaining applications of good quality. However as the frameworks provide the main concepts for lots of applications, a framework must be reusable, maintainable and expandable for each application. Developing a framework which has these properties is a hard job. Using design patterns in framework development process, makes the process easier and helps achieving reusable, maintainable and expandable frameworks. In this work, developing a design patterns based framework for the applications, which will be developed for the financial departments of the universities, is examined and a sample framework is developed. In the framework modules, the purposes of the chosen design patterns are explained and the effects of using design patterns on the reusability, maintainability and usability characteristics of the framework is also explained.
