Indexed Sequential Access Notes:
Indexed Sequential Access is a method that modifies the direct access method. Basically it combines both, the direct and sequential method. In this method, the index is nothing but a pointer to the memory block. The direct access is used to access a record in a file. The main advantage of this method is that both direct and sequential access of files is possible.
