Change set
A change set is a set of changes that result from a change request .
In software development, a change set model is a special concept for managing changes to software within the framework of software configuration management (SCM). Changes to the software from the SCM system are not viewed primitively as physical changes at the file or source object level, but rather several changes to files, objects or components that logically belong together and the achievement of a single goal - for example the correction of a software error - serve, are registered as a clear change set, i.e. as a change set . This higher-level form of managing changes relieves the user, as he no longer has to memorize the logical relationships between individual physical changes.
Technically, a change set is saved by combining the deltas of those software components that have changed compared to the previous version or configuration to form a clear change set. If necessary, several change sets can be grouped, named and combined into higher-level entities, which can then be managed in the same way as the change sets themselves.
Today, a check-in (commit) is sometimes referred to as a change set. This set of changes to files, which is entered into a version management system (committed) in one step , can, however, be changed retrospectively in modern systems.
