Hierarchical Model of Data

The Hierarchical Model of Data organizes information in a tree-like structure, where data is arranged in records, and each record contains related fields. These records are connected in a parent-child relationship, meaning a parent record can have multiple child records, but each child is linked to only one parent. This model reflects real-world relationships and allows efficient access to related data. For example, a company database might have a "Departments" record as the parent, with multiple "Employees" records as children. It helps organize complex data logically but can be rigid if relationships change frequently.
