Autosave
The system always keeps the
data in the main memory synchronized with the data on the disk (or database).
In other words, the user does not need to constantly save the changes to avoid
losing his work.
Example 1: Memos in Palm Pilot
The user simply opens and
closes memos in the Palm Pilot. He never explicitly saves them, but they are saved
automatically by the system.
Example 2: Autosave in Word++ [Laakso01]
The Word++ prototype writes
the user’s changes continuously to the disk, i.e. the data between the main
memory and the disk is synchronized. Users do not have to face the
implementation model, and when closing a document, they never get the error-prone
“Do you want to save changes?” dialog box that breaks their work flow.
