What methods should be used to build the database structure for high concurrency applications?

For high-concurrency applications working with a database, it is important to:

• Use transactions to ensure data integrity
• Apply locking mechanisms (e.g., optimistic or pessimistic locking)
• Use a connection pool for efficient resource management
• Design the database structure considering indexes and normalization to minimize conflicts
• Consider using thread-safe ORM or libraries

For example, in Android with Room, you can use the @Transaction annotation for atomic operations and LiveData for updating the UI without locks.
