Applying and evaluating architectural patterns on a stock trading case study

Teaching architectural and design patterns is a difficult task and not easy to understand by the students as patterns are expressed at a higher abstraction level than programming language constructs or graphical UML notations. Also there is a lack of detailed examples of how patterns are applied to realistic projects and how the impact of using such patterns is evaluated. To address this issue, this paper presents detailed application and evaluation of two architectural patterns to a real Stock Trading application. The presented examples were helpful to students to get a deeper understanding of the topic.
