The hierarchical data model

How did the "HIERARCHICAL DATA MODEL" start? What are its constraints?

Please provide more context with this question. The hierarchical model can refer to hierarchical storage management (HSM) or to hierarchical structured databases (typically prior to relational databases). For the most part, neither is that interesting today. HSM is probably a little more relevant, but the implementations are difficult and problems can be very difficult to resolve. It began as a tool for managing relatively expensive disk storage in mainframe systems.

Today it can be argued that disk capacity is so cheap that HSM no longer has a purpose.
