Indexing is a crucial technique in database management and information retrieval that enhances the speed of data retrieval operations by creating a data structure that allows for efficient querying. It involves maintaining an auxiliary structure that maps keys to their corresponding data entries, thus reducing the time complexity of search operations.

Indexing

Database management involves the use of software to store, retrieve, and manage data in databases, ensuring data integrity, security, and accessibility. It is crucial for supporting data-driven decision-making and efficient operations across various applications and industries.
