Data Schema

A data schema is a structured blueprint that defines how data is organized, stored, and related within a database or information system. It specifies the types of data (like names or dates), how they are categorized, and how different data pieces connect. Think of it as a detailed map or plan that ensures all data is consistently recorded and easy to find, update, or analyze. This structure helps maintain data integrity and makes sure everyone using the system understands how the information is arranged.
