In a COBOL application that manages inventory data, you encounter a situation where multiple entries with the same product code exist. How would you handle these duplicate records to calculate accurate inventory quantities?
- Implement a COBOL program to aggregate quantities for each product code
- Sort the inventory data based on product codes to identify duplicates
- Use a database query to identify and merge duplicate entries
- Utilize a COBOL array to store unique product codes and their quantities
Utilizing a COBOL array to store unique product codes and their quantities is an effective approach. This allows for easy comparison and aggregation, ensuring accurate inventory quantities for each product code in the COBOL application.
