You must have the Oracle Rdb READ privilege for a database to use
    the INTEGRATE DATABASE statement.

    If the data dictionary was not installed when a particular
    database was created, you can use the INTEGRATE statement to
    build the dictionary definitions from the database.

    You can also periodically use the INTEGRATE statement to
    ensure that the database and data dictionary definitions remain
    synchronized with each other.

    INTEGRATE starts a transaction which can be completed by a COMMIT
    or canceled by a ROLLBACK statement.
