| Zusammenfassung: | A table can be replaced with a view transparently to the application. For example, a data dictionary can specify that the view is to be substituted for the table. At runtime, application operations on the table are redirected to be performed on the view. Validation can be performed to ensure congruence between the table and the view. Can be useful for situations where a view with enhanced functionality is desired to be used in place of the table without re-coding the application. |
