When do we throw RecordNotFoundException?
My interpretation is that during every database operation, do a check of the record the client has with the same record in the database field by field, except in null values. If the check returns false throw a RecordNotFoundException.
is this ok.
thanks.

My assignment specifies the methods in the xfc that throw it. If yours doesn't I'd say any time you look for a record that is logically deleted or beyond the last record in the file, you'd throw one.

My earlier statement should have read, How to throw RecordNotFoundException . (Sorry about that)
What comparison should be done to identify that a particular record is changed.
Do we need to compare all the fields or just a primary key we assign to teh record.

How are u all implementing compare?
Client A is seeing bunch of records on his screen. Client wants to modify a record for eg. the size of the room.
ClientB: in the mean time has changed the size or some other field of the record.
Should client A be thrown a recordnotfoundexception? because the original record has been modified, but the record number is still the same.

thanks.
