Dependency management, often referred to as dependencykezelést, is the process of managing the dependencies of a software project. Dependencies are external libraries, frameworks, or modules that a project relies on to function. Effective dependency management is crucial for maintaining the stability, security, and performance of a software application.

Dependency management involves several key activities:

1. **Identification**: Recognizing and documenting the dependencies required by a project. This includes both direct dependencies (those explicitly declared) and transitive dependencies (those required by other dependencies).

2. **Versioning**: Specifying the versions of dependencies to ensure compatibility with the project. This can include using version ranges, exact versions, or version constraints.

3. **Resolution**: Automatically or manually resolving dependencies to ensure that all required versions are available and compatible. This may involve downloading dependencies from repositories or using a local cache.

4. **Conflict Resolution**: Handling situations where multiple dependencies require different versions of the same library. This can involve selecting a compatible version or modifying the project's dependencies.

5. **Updating**: Regularly updating dependencies to benefit from new features, bug fixes, and security patches. This process should be carefully managed to avoid introducing breaking changes.

6. **Verification**: Ensuring that dependencies are secure and do not introduce vulnerabilities. This may involve scanning dependencies for known vulnerabilities and using tools to assess the security posture.

7. **Documentation**: Maintaining clear documentation of dependencies, including their purpose, versions, and any relevant configuration details.

Dependency management tools, such as Maven, Gradle, npm, and pip, automate many of these processes, making it easier for developers to manage dependencies efficiently. However, manual intervention may still be required for complex projects or special cases.

Effective dependency management is essential for modern software development, as it helps ensure that projects are built on a solid foundation of reliable and secure components.
