Data Hierarchy

Data hierarchy is the organized structure of data from broad to specific levels. It starts with a database or a collection of information, which contains files or records. Each record includes fields or attributes that store individual pieces of data. These fields hold specific data points, such as a name or date. The hierarchy helps organize and manage data efficiently, making it easier to retrieve and analyze information. Think of it like a filing system: the whole collection (database), individual files (records), and inside each file, individual pieces of information (fields).
