From entry database in glossary Artificial Intelligence: humans at the heart of algorithms
A database is software that manages data including storing, indexing and performing queries. Some are internal to an application, but many run as a service used by multiple applications, either running on a central computer or using some form of cloud service. The most common forms are relational databases (effectively collections of large, interconnected tables), which typically use the SQL query language, and noSQL databases, which use simple key-value bindings to JSON objects.
