Abstract
In a database, a database manager can generate a view, which can be considered as a subset of the database, and which is placed outside the database for use without disturbing the database. However, if the database changes, the views will not reflect those changes, because the views are separate from the database. To solve this problem, a process called “refreshing” keeps the views consistent with the data within the database. But different refreshing approaches are used: some views require immediate refreshing when the database changes, other types can be refreshed at later times, and still other types can be refreshed at different times and intervals. The invention presents a system which keeps data consistent among the views and the database, despite the different times of refreshing undertaken.
