Getting global objects
To "Get" a global object means that you can retrieve a copy of the object without putting a lock on it or formally checking it out. You can also get an object even if it is locked to another user.
Note:  Both getting and checking out an object overwrite any existing
		  copies in the run-time database with the version currently in the master
		  database. This means that you cannot make changes made to a "get" version
		  permanent, as you cannot check in a "get" version, and any changes you have
		  made are overwritten when you check it out.
