data-storage

I'm starting to learn about COBOL. I have some experience writing programs that deal with sql databases and I guess I'm confused how cobol stores and retrieves data that is stored in a mainframe for example. I know that it's not like relational databases but every example program I've seen takes data straight from the command line and I know thats not how real world COBOL programs process the data. Can someone explain or show me a good resource that can explain it?
