Data store
A data store is a data repository of a set of integrated objects. These objects are modeled using classes defined in database schemas.[1] Data store includes not only data repositories like databases, it is a more general concept that includes also flat files that can store data.[2]
Some data stores do represent data in only one schema, while other data stores use several schemas for this task. An example are RDBMS-based data stores like MySQL or PostgreSQL.
Types
Data stores can be of different types.
- The widely used data store type are relational databases. (Examples: MySQL, PostgreSQL, Microsoft SQL Server, Oracle Database)
- Object-oriented databases, like Caché or ConceptBase. They can save objects of an object-oriented design.
- Operational data stores
- Schema-less data stores, like Distributed data stores (e.g. Apache Cassandra or Dynamo).
- Paper Files
- Data Files (spread sheets, flat files etc)
