When a database index is created on a column or a set of columns, the database system creates a separate data structure that organizes the indexed values in a sorted manner. This structure allows the database to quickly locate the desired data based on the indexed column's value. Think of an index as a reference guide that helps the database find relevant information without having to read every row in the table.
