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

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

Paper files
