Indexed Sequential Files

An index is inserted to the sequential file to provide random access. An overflow area required to be maintained to permit insertion in sequence.

Indexed Flies

In this file organization, no sequence is imposed onto the storage of records in the data file; thus, no overflow area is required. However, the index is maintained into firm sequence. Multiple indexes are allowed on a file to improve access.
