1.	What are the problems associated with using ordered sequential files?
Answer» The main nature of ordered sequential files is that the records are arranged BASED on some key field(s). When a user wants to perform OPERATIONS like insert or deletion, then the order based on the field(s) should be maintained at all times. This is attained only by creating a new file where we insert or update or delete the records within the new file and then maintain the ordered nature. All these take PLACE on the disk directly and the time required to access data on disk is the main bottleneck while processing any functionality. This reduces the SPEED of computation and slows down the SYSTEM unnecessarily if we try to use ordered sequential files whenever not needed.
