This documentation outlines the database architecture and flow within the GymBrah application, focusing on the athlete onboarding process facilitated by the athlete_code system. The following diagram illustrates the interaction between key tables:

1️⃣ Gym Registers an Athlete

• Creates a new athlete record with a unique athlete_code.
• Sends an invitation email/SMS containing the athlete_code for the athlete to join.

2️⃣ Athlete Signs Up

• If the athlete's email matches an existing invite, the user is automatically linked to the athlete record.
• If not, the athlete can manually enter the athlete_code to associate their account.

3️⃣ Workout Assignment & Tracking

• The workout_athlete table manages the association between workouts and athletes.
• Gyms can assign workouts to athletes even before the athletes have completed their signup process.

• Prisma Migrate: Use Prisma Migrate to handle schema changes smoothly. Run npx prisma migrate dev to apply migrations.
• Client Generation: After updating the schema, generate the Prisma client with npx prisma generate to ensure type safety and access to the latest models.

• Relations: Utilize Prisma's relational mappings to maintain referential integrity between tables.
• Transactions: Use transactions for bulk operations to ensure atomicity and consistency.

• Unique Codes: Ensure athlete_code uniqueness by enforcing constraints in the Prisma schema.
• Validation: Implement front-end and back-end validation for athlete_code during the signup process to prevent errors.

• Indexing: Index frequently queried fields such as user_id, athlete_code, and foreign keys to enhance query performance.
• Lazy Loading: Utilize Prisma's lazy loading features to fetch related records only when necessary, reducing initial load times.

• Authentication & Authorization: Protect sensitive endpoints with robust authentication mechanisms and ensure proper authorization checks.
• Input Sanitization: Sanitize and validate all inputs, especially user-generated content and athlete_code, to prevent injection attacks.

• Database Backups: Regularly back up your PostgreSQL database to prevent data loss. Consider automated backup solutions.
• Performance Monitoring: Use tools like PgAdmin or other PostgreSQL monitoring solutions to keep an eye on database performance and identify bottlenecks.

• Version Control: Keep your Prisma schema and migrations under version control to track changes and collaborate effectively.
• Environment Management: Use environment variables to manage different configurations for development, staging, and production environments.

By adhering to these guidelines, you can ensure a robust, secure, and maintainable database structure that supports the GymBrah application's growth and scalability.
