Database Design is the process of creating a structured framework for storing and managing data in a database. It involves defining how data will be organized, how different data elements relate to each other, and how they can be accessed efficiently. A well-designed database ensures data integrity, reduces redundancy, and improves performance. Key components of Database Design include identifying the data requirements, creating Entity-Relationship Diagrams (ERDs) to visualize relationships, and normalizing data to eliminate unnecessary duplication. Effective Database Design is crucial for applications ranging from small websites to large enterprise systems, as it directly impacts usability and scalability.
