Why Do We Need Databases?

Most medium and large businesses rely on databases to store customer information. Because this information is accessible wherever Internet access is available, customers don't have to go to a local banking branch, for example, to access their account information.

Databases are also used for scientific research. Instead of having to track down hundreds or thousands of weather stations, researchers can rely on databases that store weather information from around the globe. This greatly reduces the workload needed to calculate statistical information.
