Sequential File Organization in Database
How are the sequential files stored?
A sequential file can be stored on a sequential access device such as magnetic tape or on a direct access device such as magnetic disk.
What are the components of sequential file?
The indexed sequential file architecture comprises three components which includes the main file where the records are stored sequentially, an index allowing quick access to records, and an overflow area for storing newly inserted records. This arrangement promotes efficient data retrieval and updates.
What are the purposes of file organization?
The purposes of file organization are: Records should be stored effectively so that storage expense must be least. The insert, delete, or update operations on the records should be quick. Inserting, updating, or deleting do not result in duplicate records.
Sequential File Organization in Database
Sequential file organization is the simplest type of file organization, where files are stored one after the other, rather than storing different files in rows and columns (in a tabular form), storing data in rows. In this article, we will learn about sequential file organization and its advantages and disadvantages in databases. We will understand various methods of sequential file organization.
