The data records for a database instance, including their index entries, are designated as application data. The application data in a table or an index occupies at least one page in a data volume. A very large table can extend across all data volumes of the database instance.
It is not possible to determine in which data volumes the application data in a table are located. However, it is not necessary to know this.
