An index is a basic building block of a database that is used to improve the speed and efficiency of data access. It works like an index in a book, organizing data based on specific fields. This allows for faster searching and sorting of data. Tables represent the actual data, constraints enforce rules on the data, and timestamps track when data was last updated but do not directly improve data access speed.
