Here are five common database models: Flat File: Data are stored in files, but there is no connection between the files. This model takes the form of a graph, where relationship types are arcs, and object types are nodes. There were two popular data models in this decade: a network model called CODASYL and a hierarchical model called IMS. Object Relational Model: These models have created an entirely new type of database, which combines database design with application program to solve specific technical problems while leveraging the best of both worlds. Depending on the type, structure, data model, data store, and intended use case of your data, different systems are likely to be better suited to your needs.

The data model is a simple network, and link and intersection record types (called junction records by IDMS) may exist, as well as sets between them . Each piece of data is given a name, called a “key.” That key is used to find and retrieve that data. Document databases work on this model. The schema or querying mechanism required, your consistency or latency requirements, or even transaction speed (including real-time) can also influence your decision.
