The role of a database schema is to define the structure, organization, and relationships of data within a database. It acts as a blueprint, outlining how data is stored, including tables, fields, data types, and constraints. By establishing a clear schema, database administrators ensure data integrity and facilitate efficient querying and reporting. Well-designed schemas help optimize database performance and support the application’s functionality by enabling accurate data retrieval and management. Furthermore, a robust schema facilitates collaboration between developers and stakeholders, providing a clear understanding of the data landscape and ensuring consistency in data handling practices.
