Git – the single source of truth

In custom development projects, the source code is maintained in version control systems. These systems let developers work together on the same code base so that they can constantly introduce new features and/or fix bugs without conflicting with the changes of others. One of the reasons we use such code repositories (version control systems) is to provide end-to-end forward and backward traceability between code in production (the running application) and source code changes that have been made before pushing a version to production. In modern DevOps tools, in the project management part, the work items that need to be developed are directly linked to code changes that are made by developers. Version control systems provide a history of items and support transaction-like changes that span over multiple files and folders in repositories. These are very often represented as version or history trees.
