The index of a database is a data structure that improves the speed of data retrieval operations by providing quick access to specific data. Here are some key points about indexes in the context of database management systems like SQL:

Example Use Case:

Suppose we have a table called employees with columns employee_id, name, and department. We frequently query this table by employee_id. We can create an index on employee_id to speed up these queries:
