Before delving into the topic, let's gain some understanding of what a repository is........... What is a repository? A repository is a centralized storage location where data, files, documents, or other digital assets are stored and managed. It serves as a single source of truth for organizing, versioning, and accessing these assets. In the context of software development, a repository typically refers to a version control system, where developers store and manage source code, configuration files, documentation, and other project-related files. Version control systems like Git, Subversion (SVN), and Mercurial are commonly used repositories in software development. In addition to version control systems, repositories can also refer to databases, file systems, content management systems (CMS), or any other structured storage system used to manage digital assets.

Now, suppose you realize that a particular recipe's key ingredient needs to be changed, and you've already written down all the specific instructions for that recipe. If you catch this mistake right after creating the recipe, you can simply erase the instructions, change the key ingredient, and rewrite the instructions. However, if you discover this error later, after many copies of the recipe have been shared (analogous to rules being locked in an old version), things get trickier. In the digital world, this is like having a database table with predefined rules (recipe instructions) and realizing that you need to change the key (key ingredient). It's not as simple as starting from scratch, especially when the rules are already locked...
