Introduction to Database Design

Database Design involves structuring a database to efficiently store, retrieve, and manage data supporting various business processes. It entails defining how data is stored, organized, and accessed in systems ranging from simple single-user databases to complex multi-user systems. An example scenario illustrating this is a retail company aiming to optimize inventory management, where Database Design ensures product information, stock levels, and supplier data are systematically organized for easy access and analysis.
