Identification and implementation of observer and state pattern in internet banking application

In the field of the software systems. the software architecture plays a important role in which we can frame the architecture of our system. Using software architecture we describe the elements involved in the system, the properties of each element and also about relationships between the elements. After developing the architecture of our system it is very important to evaluate the architecture of that particular system in order to check whether it satisfies the requirements of the stakeholders. The purpose of evaluating the software architecture is to identify the potential risks and also to check whether the business goals and the requirements of the customers are satisfied. We can achieve several quality attributes like performance, maintainability, testability by evaluating the software architecture. There are lot of methods available to evaluate the software architecture but in this paper we are going to discuss about the evaluation method called SAAM (Software Architecture Analysis Method), in which in this method we are going to evaluate using scenarios. In this paper we are going to deal with the internet banking system, And also we discuss about how the SAAM evaluation method is applied to this internet banking system.
