Data store

Repository for data collection storage and management

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.[1]

A database is a collection of data that is managed by a database management system (DBMS), though the term can sometime more generally refer to any collection of data that is stored and accessed electronically. A file is a series of bytes that is managed by a file system. Thus, any database or file is a series of bytes that, once stored, is called a data store.

MATLAB[2] and Cloud Storage systems like VMware,[3] Firefox OS[4] use datastore as a term for abstracting collections of data inside their respective applications.

## Types

[edit]

Data store can refer to a broad class of storage systems including:

* Paper files
* Simple files like a spreadsheet
* File systems

* Object-oriented databases. They can save objects of an object-oriented design.
* NoSQL databases
* Key–value databases
* Wide-column stores
* Graph databases
* Distributed data stores
* Directory services
* VMware uses the term datastore to refer to a file that stores a virtual machine[5]
