Lock-Based Version Control
Lock-based version control is a system where files are locked for exclusive editing by one user at a time to prevent conflicts. It operates by requiring users to 'check out' a file, which locks it for their use, and then 'check in' the file to release the lock and save changes. This approach is simpler but less flexible than modern version control systems, as it serializes access to files.
Developers should learn lock-based version control when working in environments with binary files (e.g., images, design documents) or legacy systems where merge conflicts are difficult to resolve. It is useful in scenarios where strict control over file access is needed, such as in small teams or for non-text assets, but it can hinder collaboration due to its blocking nature.
