Team-based development is the integration of the Model repository with a third-party version control system. The version control system saves multiple versions of objects and assigns each version a version number.

You manage object versions through the Developer tool. You can perform actions such as checking objects out and in, viewing and retrieving historical versions of objects, and undoing a checkout.

The Model repository protects objects from being overwritten by other members of the development team. If you open an object that another user has checked out, you receive a notification that identifies the user who checked it out. You can open a checked out object in read-only mode, or you can save it with a different name.

When the connection to the version control system is active, the Model repository has the latest version of each object.

The Model repository maintains the state of checked-out objects if it loses the connection to the version control system. While the connection with the version control system is down, you can continue to open, edit, save, and close objects. The Model repository tracks and maintains object states.

When the connection is restored, you can resume version control system-related actions, such as checking in or undoing the checkout of objects. If you opened and edited an object during the time when the connection was down, the Model repository checks out the object to you.
