What are the key differences between a hierarch... - SS3 ICT Database Question

In a hierarchical database, data is organized in a tree-like structure with parent-child relationships, where each child can have only one parent. In contrast, a network database also uses a tree structure but allows each child to have multiple parents. Key differences include:

 

• Flexibility: Network databases are more flexible due to multiple parent-child relationships, while hierarchies are more rigid.
• Complexity: Network databases can represent complex relationships better.
• Data Integrity: Hierarchical databases are simpler to maintain in terms of data integrity, as they have stricter rules.
