A database model is a type of data model that determines the logical structure of a database and fundamentally determines in which manner [[data]] can be stored, organized, and manipulated. The most popular example of a database model is the relational model (or the SQL approximation of relational), which uses a table-based format.

Common logical data models for databases include:
*[[Navigational database]]s
**[[Hierarchical database model]]
**[[Network model]]
**[[Graph database]]
*[[Relational model]]
*[[Entity–relationship model]]
**[[Enhanced entity–relationship model]]
*[[Object database|Object model]]
*[[Document-oriented database|Document model]]
*[[Entity–attribute–value model]]
*[[Star schema]]

An object–relational database combines the two related structures.

[[Physical data model]]s include:
*[[Inverted index]]
*[[Flat-file database|Flat file]]

Other models include:
*[[Multidimensional database|Multidimensional model]]
*[[Array DBMS|Array model]]
*[[Multivalue model]]

Specialized models are optimized for particular types of data:
*[[XML database]]
*[[Semantic data model|Semantic model]]
*[[Content store]]
*[[Event store]]
*[[Time series database|Time series model]]
