    Write a function that converts database field names in the adaptive learning system from snake_case (used in the backend database) to camelCase (used in the frontend JavaScript code), maintaining data consistency across the learning platform's architecture. The function should handle any valid snake_case string containing only lowercase letters and underscores, and must preserve the semantic meaning of the field names while adapting them to frontend coding standards.
