Hierarchical Model

A hierarchical model is a way of organizing information or data in layers or levels, where each level builds on the one below. Imagine a family tree: at the top are grandparents, below are parents, and further down are children. In data or decision-making, this structure helps manage complex relationships efficiently by grouping related items together. It simplifies understanding by providing a clear structure, making it easier to analyze, retrieve, and manage data by navigating from broader categories to more specific details.
