Description: The ‘Fetch Operation’ refers to the action of retrieving data from a database, a fundamental process in information management. This process often involves the use of cursors, which are structures that allow navigation through a result set from an SQL query. Data retrieval is essential for interacting with databases, as it enables users and applications to access stored information efficiently and effectively. Fetch operations can vary in complexity, from simple queries that return a set of records to more complex operations involving the manipulation of large volumes of data. Optimizing these queries is crucial for improving database performance, especially in environments handling large amounts of information. The way queries are structured and how indexes are used can significantly impact the speed and efficiency of data retrieval. In summary, the ‘Fetch Operation’ is a key component in database management, allowing users to access and manipulate data effectively.
