    Create a function for the adaptive learning platform that transforms database field names from snake case (e.g., student_performance_score) to camel case (e.g., studentPerformanceScore) to ensure consistent data handling between the backend learning management system and frontend student interface. The function should handle any valid snake case input string containing only lowercase letters and underscores, converting it to its camel case equivalent while preserving the original meaning of the field name.
