Creating a new version
As previously discussed, we can decide to mark a new milestone for a certain table;
in other words, we can start a new version. We will now create a new version as
an exercise.
In the Tracking panel for the author table, we see the dialog for creating version 2
(as the highest one is currently version 1):
We notice that each version can track its own set of statements; versions are
independent from each other in this matter. Here, we have decided that version 2
will track only data-definition statements. We now see something interesting relative
to the status of these versions, as shown in the following screenshot:
Indeed, version 1 was automatically marked as not active ; it went into some kind of
historical status. We can also have a look at version 2's snapshot, which reflects that
the name column is a VARCHAR(40) .
