What type of model do you like DBAs?


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.
