A friend recently asked me for examples and the differences of a relational database model, hierarchical database model, document database model and graph database model. Good question eh? SQL Server is a relational database but what about all the latest database models out there.
Here’s my short list of database models that have been and/or are currently used for production databases.
- Relational model
- Hierarchical model
- Network model
- Object-oriented model
- Object-relational model
- NoSQL database models
- Graph database model
- Multi-value model
- Document model
- Other database models
- Inverted file model
- Flat model
- Multidimensional model
- Semi-structured model
- Context model
- Associative model
- Less common database models
- Semantic model
- XML database
- Named graph
- Triple store
The following articles helped my friend to see actual examples and differences in the above database models.
