Updated: 8/11/2023

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 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.

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 differences between serial file organization and sequential file organization?

Serial file organization stores records in a linear format, while sequential file organization stores records in a specific order defined by a key field. In serial file organization, records don't have to be retrieved in a specific order, whereas in sequential file organization, records are retrieved based on the key field's order.

What is difference between sequential file and index file?

the index file is more sicurity checked and contains more information about the acess . for example An indexed file is a computer file with an index that allows easy random access to any record given its file key.The key must be such that it uniquely identifies a record. If more than one index is present the other ones are called alternate indexes.The COBOL language supports indexed files with the following command in the FILE CONTROL section. however a sequential file isA file that contains records or other elements that are stored in a chronological order based on account number or some other identifying data. In order to locate the desired data, sequential files must be read starting at the beginning of the file. A sequential file may be stored on a sequential access device such as magnetic tape or on a direct access device such as magnetic disk. Contrast with random-file.Read more: sequential-fileContent of sequential file can't be accessed directly while index file content can be accessed directly through pointer. Sequential file is time consuming in comparison with index file.Example: Index of book - index fileExample: Bundle of plates - sequential file

What are the advantages and disadvantages of indexed-sequential file organization?

Well, honey, let me break it down for you. The advantage of indexed-sequential file organization is that it allows for quick access to records through the index, making retrieval faster than in sequential files. However, the downside is that maintaining the index can be a pain in the rear, especially as the file grows in size. So, it's like having a fancy sports car - it's great when it works, but it can be a headache to maintain.

Which file organization is most efficient for a file with a high degree?

sequential

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.
