An exception should be raised if there is no record containing the primary key provided in the Transfer Object. • delete(primaryKey:ID):void Delete a record given a primary key. An exception should be raised if there is no matching record. • find(constraint:TransferObject, relOp:Comparator): Iterator Find Transfer Objects having attribute values matching the values provided in the constraint. Comparator interface is provided to compare the constraint with the Value Objects retrieved from the data source.

Find(query:Query):Iterator 35 36 Return an Iterator object containing all records matching the query. The query must evaluate a set of Transfer Objects of the same class as managed by the Data Access Object. An iterator containing zero records is a valid result and should not raise an exception. In cases in which some methods cannot be implemented due to limitations in the persistent store, the method can either raise an exception or provide a default implementation. It is important to note that all Transfer Object instances passed to or returned from these methods in a particular Data Access Object must be of the same class the Transfer Object class that is managed by the Data Access Object.

4. Deposit amount x to account A. 5. Look up event at t0 (yesterday's final balance) for account A. 6. Recalculate average balance for account A using event log entries between t0 and tN event at time tN 1. 7. 8. 00 transferred to A This transaction accurately calculates the correct interest by using the event log to recalculate the average balance, omitting the event at t1 that otherwise would cause the interest amount to be incorrect. Note, however, that to meet possible legal requirements for audit logging, the event log is kept intact in order to preserve a record of all account movements, regardless of whether they are rolled back or not.
