What are sequential access files?
The file(s) (data) which are accessed in a sequential or a orderly manner is called as a sequentially accessing a file.
Implementation of index sequential file organization?
Indexed sequential file organization. =In indexed sequential file organization, the records arestored in sequence according to a primary key and an index is created to allow random access of the file. This type of organization also allows the file to be accessed sequentially. Indexed sequential is the most commonlyused type of file organization. writer-k.k.b -montanna
Difference between direct sequential file and index sequential file?
Explain the difference between sequential and direct file access.A. Sequential access to data is used when the data has to be read from the start, in sequence. It is the normal method of access for magnetic tape. Direct access is used when it is possible to jump directly to a file or data item without reading through all the items stored before it. This is the normal method used for hard disks.
What is the 3 diff methods of organizing file?
Sequential, Relative, Indexed.

What are the advantages and disadvantages of indexed-sequential file organization?
Advantages of indexed-sequential file organization include efficient access to records through an index and sequential storage for faster retrieval. However, disadvantages may include increased complexity in managing the index and potential performance degradation due to index maintenance overhead.

What are the advantages of indexed-sequential file organisation?
Indexed-sequential file organization allows for efficient storage and retrieval of records by combining the benefits of sequential access (fast for batch processing) and direct access (quick for individual record retrieval). It provides faster access to records compared to purely sequential files while maintaining sequential organization for improved batch processing performance. The index allows for quick access to specific records without needing to search through the entire file.
What is the difference between the file maintenance and file organization?
file organization is of 3 types sequential,direct and indexed sequential where how data is accessed in eash file is decided where as file maintainence is
What are sequential access files?

What is a indexed sequential file?
An indexed sequential file is a type of file organization where data records are stored sequentially in the order of key values. An index is maintained to help locate records quickly. This combination of sequential storage and indexing allows for efficient access to data in both sequential and random access patterns.
What are the disadvantages of random access?
Assuming you're talking about tape storage.. mainly speed ! With sequential access, the medium has to be constantly rewound back to the start before the next relevant data can be accessed. The constant rewinding slows down the access time.
