I do other things besides COBOL but I maintain and occasionally enhance many COBOL applications:
- Item Database (SKU, UPC, attributes)
- Stock Status (Sales, Onhands, process sales transactions from POS systems)
- Replenishment (Create vendor and DC orders to stores)
- Reporting (Report sales and other performance data by stores, departments, classes, etc..)
- Pricing (make and maintain current and future price changes, send to store when needed).
- Many other applications (15+)
They have been saying they are going to get rid of these applications for over 20 years now. I am still waiting...
