A software dependency is a library or framework that a software application requires to function correctly. These dependencies provide essential functionality and resources, enabling developers to build applications more efficiently. However, managing software dependencies can pose challenges, as updates or changes to a dependency may introduce compatibility issues, vulnerabilities, or alter the application's behavior. Effective dependency management involves tracking and updating these components to ensure that applications remain secure, performant, and compliant with current standards. Understanding and addressing software dependencies is crucial for maintaining robust and reliable software systems.
