 Application Data 

The application data of a database comprises all data records of this database, together with their index entries. A data record corresponds to one row in a base table. This means that the application data comprises all rows of all base tables, plus the index entries created for the base tables.

As a minimum, the application data of a table or index can use just one data page . As a maximum, a table can extend across all data volumes of the database instance.A table increases or decreases in size automatically without administrative intervention. As a rule, database-internal striping distributes the data belonging to a table evenly across all the data volumes. This means that you cannot determine how the tables are assigned to the individual data volumes, but this is not significant.
