Summary

Throughout this chapter, we have explored the definition and importance of cross-cutting concerns in software development. These concerns are FRs that affect multiple parts of an application and can have a significant impact on its overall design and quality.

We have examined various common examples of cross-cutting concerns, including logging, error handling and exception management, security and authorization, caching, performance optimization, transaction management, validation, localization and internationalization, and monitoring. These concerns often require repetitive code or modifications throughout the application, making them challenging to manage and maintain.

By properly handling cross-cutting concerns, developers can improve code maintainability, enhance system performance, increase security, and facilitate internationalization and localization efforts. Identifying and addressing these concerns early in the development process is crucial for building high...
