Indexed file: Indexed file accessing mechanism provides quick access to records for the database and it does not suffer from clustering issue. Indexed file does not contain collision leading to overflow. Hash file: The maintenance cost is low and it does not add this overhead. It provides low access as compared to the indexed file and clustering is the main issue in the hashed files. Collision leads to overflow of the bucket in the hashed files.
