indeksskanning
Indeksskanning, also known as index scanning, is a method used in database management systems for retrieving data efficiently. This technique involves using an index—a data structure that improves the speed of data retrieval operations—rather than scanning the entire table sequentially. Indeksskanning allows for quick access to specific rows based on key values, significantly reducing query response times.
The process begins with the database engine consulting the index to locate the position of the desired
Indeksskanning is particularly advantageous when queries involve search conditions on indexed columns, such as WHERE clauses,
In summary, indeksskanning is a fundamental technique that enhances database performance by utilizing indexes for rapid
