Database locking

All node and card properties are stored in a single OTM database. When Node
or Card Properties are opened, the data for a given node (including card
properties) is then locked. If a second user tries to access a property sheet in
the same node at the same time, the second user is given the option of
overriding the lock. If the second user decides to override the lock and the
first user has made changes and then clicked "OK" or "Apply", the first user
provided with a message that says that their changes have been lost (see the
second dialog box in Figure 137 on page 460). This message only appears if
changes have been made.
If an attempt is made to open a property sheet in the node after rebooting the
PC, the first dialog box in Figure 137 appears. In this example, a property
sheet was open when the database was taken over by another user.
