The indexed sequential access method (ISAM) provides the flexibility to use both sequential and random access to records. Records can be accessed sequentially or randomly, depending on the number being accessed. The method uses an index to locate records quickly, which allows for fast random access. Sequential access is still an option for accessing records in order, which can be useful for certain operations. Therefore, ISAM provides the advantage of both sequential and random access in a single method.
