Do you have practical experience in designing database table structures?

Yes, I have practical experience in designing database table structures. This includes:

• Analyzing data requirements and relationships
• Designing database schemas with normalization to eliminate redundancy
• Defining data types and constraints (e.g., primary keys, foreign keys, unique indexes)
• Creating ER diagrams to visualize structure
• Optimizing structure for performance and scalability

For example, when designing a user table, I defined fields like id (PK), username (unique), email, password_hash, and relationships with other tables such as roles or profiles.
