Computer databases typically contain aggregations of data records or files, containing information about sales transactions or interactions with specific customers.

In a relational database, digital information about a specific customer is organized into rows, columns and tables which are indexed to make it easier to find relevant information through SQL or No SQL queries.

The hardware, operating systems or database applications in a heterogeneous distributed database may be different at each of the locations.

A cloud database is a database that has been optimized or built for a virtualized environment, either in a hybrid cloud, public cloud or private cloud.
