Software patterns provide solutions to recurring design problems, provide a way to reason about the quality attributes, and support stakeholders in understanding the system. Naturally, the use of software patterns emerges from the requirements of the software. Use Cases have been a traditional and authentic approach to document these requirements. We propose a way to mine these patterns by sing use cases and advocate their significance in saving resources and time. For this purpose, an open-source system is discussed and four design patterns are mined with the help of use cases elicited from the documentation and literature available for the selected system. Patterns mined in this…
