Hierarchical databases are set up in a tree-like structure, with each node having a parent and several child nodes. This structure is often used for storing data that has a clear hierarchy or organizational structure, such as file systems or organizational charts. Relational databases, on the other hand, use tables and relationships between those tables to organize data. Object-oriented databases use objects and classes to organize and store data, and multidimensional databases organize data into cubes or hypercubes. However, neither of these database types rely on a hard-wired hierarchical structure like hierarchical databases.
