# Code Review Report for [PROJECT_NAME]

## Security Vulnerabilities
- **SQL Injection Risk**: The code uses string concatenation to build SQL queries. Recommend using parameterized queries instead.
- **Authentication Bypass**: The `authenticate_user` function does not validate user input properly. Recommend adding input validation.

## Coding Standards Compliance
- **Naming Conventions**: The function `calcTotal()` should be renamed to `calculate_total()` to follow [COMPANY]'s naming conventions.
- **Code Duplication**: The `process_data` function has duplicate logic. Recommend refactoring to a helper function.

## Performance Issues
- **Inefficient Loops**: The `generate_report` function uses nested loops. Recommend optimizing with list comprehensions.
- **Memory Usage**: The `load_data` function loads entire datasets into memory. Recommend using generators for large datasets.

## Recommendations
1. Implement parameterized queries to prevent SQL injection.
2. Add input validation to the `authenticate_user` function.
3. Refactor duplicate code in the `process_data` function.
4. Optimize loops in the `generate_report` function.
5. Use generators for large datasets in the `load_data` function.
