What is the main objective of file organization in a database system?

The correct answer is Facilitating data retrieval.

Key Points

• The main objective of file organization in a database system is to facilitate data retrieval. This ensures that data stored in the database can be accessed efficiently when needed.
  • File organization determines the physical layout of data on storage devices such as hard drives or SSDs.
  • Proper file organization minimizes data access time, improving the overall performance of the database system.
  • It helps optimize the use of storage space and ensures faster query execution by arranging data in a systematic way.
  • Techniques such as sequential, indexed, and hashed file organization are used based on the nature of data and retrieval requirements.
  • Efficient data retrieval is critical in applications requiring real-time data access, such as e-commerce platforms, banking systems, and search engines.

Additional Information

• Other objectives of file organization include:
  • Efficient storage of data: Ensuring optimal use of storage space by organizing data compactly.
  • Enforcing data security: Protecting data from unauthorized access or corruption.
  • Ensuring data integrity: Maintaining data accuracy and consistency over its lifecycle.
• However, facilitating data retrieval remains the primary focus, as it directly impacts database performance and user experience.
• Modern database systems often use advanced indexing and caching mechanisms to further enhance data retrieval efficiency.
