- Hierarchical database model: This was the first database model to be created. It was created in 1960. The hierarchical database model arranges data in a tree-like form like an organogram. The structure allows representing information using parent/child relationships: each parent can have many children, but each child has only one parent. All attributes of a specific record are listed under an entity type.
