•See and work with data from another (or the current) table in its most up-to-date state. For example, you can display data in related fields when you need current data from a related table, such as the current price of an item.

•Set up and manage data efficiently and with flexibility. Instead of creating many database tables or files with duplicate values, you store single occurrences of values and use relationships to make those values available. You can then make changes to data in only one place, which eliminates data duplication and promotes data accuracy.

•Save disk space, because data is stored in only one place.
