Question

Quizplus · Accepted Answer

The hierarchical data structure is a concept of organizing data in a tree-like structure with one parent and multiple children. This is a logical level of database architecture because it defines the relationships between data and how it can be accessed or manipulated. The physical level deals with how the data is stored and accessed on the hardware, the sequential level defines the order of access, and the conceptual level deals with the overall understanding of the data by the users.
