A data store is a repository of a set of data objects. These objects are modelled using classes defined in a database schema. A data store is a general concept that includes not just repositories like databases, but also simpler store types such as flat files etc.
Data stores can be of different types, including:
- Paper files
- Simple files like a spreadsheet
- File systems
- Email storage systems (both server and client systems)
- Distributed data stores, like Apache Cassandra, Druid (open-source data store) or Dynamo
- Directory services
- VMware uses "datastore" to refer to a file that stores a virtual machine
