Table Access (DELETE) Using B* Tree
The address table is defined via the city
primary key column. In the address table, delete an entry with the value Apach for the city primary key field.If an entry is deleted from the table, gaps appear in the data section and in the position list of the
leaf page in the B* tree. The database system closes these gaps and updates the position list to save storage space.
