In which one of the following models are the records arranged in the form of a tree ?
Explanation
The Hierarchical Model is a data model in which the data is organized into a tree-like structure. In this model, records are connected through links in a parent-child relationship. Each child node can have only one parent, while a parent node can have multiple children (one-to-many relationship). The structure starts from a single "root" node and branches downward.
Comparison with other models:
- Relational Model: Data is organized in tables consisting of rows and columns.
- Network Model: Similar to the hierarchical model but allows a child node to have multiple parents, forming a graph-like structure rather than a strict tree.
