Data store

"Datastore" redirects here. For the cloud database, see Bigtable.

A data store is a repository for persistently storing and managing collections of data which include not just repositories like databases, but also simpler store types such as simple files, emails etc.

A database is a repository of data objects where the objects are modeled using a database schema. Also, a file system is nothing but a repository that stores files. Thus any database management system or file system can be stated as an example for a data store.

MATLAB and Cloud Storage systems like VMware, Firefox OS use datastore as a term for abstracting collections of data inside their respective applications.
