The I/O from an instance of the SQL Server Database Engine includes logical and physical reads. A logical read occurs every time the Database Engine requests a page from the buffer cache. If the page is not currently in the buffer cache, a physical read first copies the page from disk into the cache.
Maintaining a version of a database opens a lot of possibilities, especially if an automated process can easily grab the current version, at runtime, using just SQL. You might, for example, have a routine that is only appropriate after a particular version. It is also very handy to be able to associate entries in an event log or bug report with the database version. No more desultory quests, when dealing with support issues, or when bug fixing, to find which database version was running when the bug happened.
