hierarchical database

(database)
A kind of database management system that links records together like a family tree such that each record type has only one owner, e.g. an order is owned by only one customer. Hierarchical structures were widely used in the first mainframe database management systems. However, due to their restrictions, they often cannot be used to relate structures that exist in the real world.

hierarchical database

A database organization method that is structured in a hierarchy. All access to data starts at the top of the hierarchy and moves downward; for example, from customer to orders, vendor to purchases, etc. Contrast with relational database and network database.
