Explaining the difference between hierarchical and network database models in IMS

In IMS, the hierarchical database model organizes data in a tree-like structure with parent-child relationships, where each child can have only one parent. This model is focused on representing relationships between entities in a one-to-many manner, making it efficient for handling simple data structures.

On the other hand, the network database model in IMS allows for more complex relationships between entities by allowing each record to have multiple links to other records. This model offers more flexibility in representing many-to-many relationships and is suitable for handling interconnected data.

In summary, the hierarchical database model is based on a top-down approach where data is organized in a tree structure, while the network database model allows for more complex relationships between entities through multiple links.
