In the ADDRESS table, the CITY column is defined as the primary key.

  1. The database system inserts the data record after the last data record on the leaf page.

    If there is not enough space on the respective leaf page of the B* tree for the new data record, the database system adds a new leaf page and redistributes the data records. More information: Rebalancing
