Automated Student Enrollment Data Validation Pipeline

Create a comprehensive Bash shell script that processes raw student enrollment CSV files from multiple sources, performing real-time data validation, cleaning, and normalization. The script must handle edge cases like duplicate entries, incomplete records, and inconsistent formatting. Implement robust error logging, generate a detailed validation report, and automatically flag records requiring manual review. Include mechanisms for secure file handling, data integrity checks, and integration with a learning management system database.
