Source Code Control Models

Last Modified: April 10, 2020

Source code control systems are built using either a centralized or distributed model.

  • Centralized Model

    In centralized source code control, a project exists in a single central repository, usually on a server. Users create a local repository on a client where they make modifications to the project, then upload their changes directly to the central repository.

    Apache Subversion® (SVN) is one example of an open-source system using the centralized model. The SVN Toolkit add-on for LabVIEW NXG adds icons to the files pane of LabVIEW NXG to show the status of files in your SVN repository. You can download and install the SVN Toolkit using NI Package Manager.

  • Distributed Model

    In distributed source code control, a project exists in a single central repository. Clients have two local repositories: a clone of the central repository and a working repository where users make modifications. Users submit modifications to the working repository often during development. When users finish development work, they push their changes to the central repository.

    Git™ is one example of an open-source system using the distributed model.
