FAQs on DSA 1.46 Part 2 : Index Sequential File Organization with Example Video Lecture - Database Management System (DBMS) - Computer Science Engineering (CSE)

1. What is Index Sequential File Organization?
Ans. Index Sequential File Organization is a method of organizing data in a file where records are stored in sequential order on the disk, and an index is created to efficiently locate records based on a key value.
2. How does Index Sequential File Organization differ from Sequential File Organization?
Ans. In Index Sequential File Organization, an index is created to facilitate quick access to records based on a key value, whereas in Sequential File Organization, records are stored in a sequential order without an index.
3. What are the advantages of using Index Sequential File Organization?
Ans. Some advantages of using Index Sequential File Organization include faster access to records through indexing, efficient searching based on key values, and support for sequential access to records.
4. Can records be inserted or deleted easily in an Index Sequential File Organization?
Ans. Inserting or deleting records in an Index Sequential File Organization can be more complex compared to Sequential File Organization due to the need to update the index structure to maintain integrity and efficiency.
5. How is a search operation performed in an Index Sequential File Organization?
Ans. In an Index Sequential File Organization, a search operation is typically carried out by first looking up the key value in the index to find the location of the record on the disk, followed by retrieving the record based on the location.
