hierarchical database model

A hierarchical database model organizes data in a tree-like structure where each record (or node) is connected to one parent record and potentially many child records. This structure reflects a set hierarchy, with relationships similar to an organizational chart or family tree. It allows for efficient retrieval of related data but can be inflexible if relationships change or become complex. Think of it as a family tree where each person (record) is linked to their parent and children, making it straightforward to see how data is connected within a strict hierarchy.
