Here is another presentation we did a the IBM Innovate conference in June 2014. Using HATS to create web services from 5250 or 3270 terminal applications is a common use case for HATS. You can also consume services either in the interface (i.e. RESTful or JSON), or through HATS macros or Business Logic (i.e. custom HATS Java code). HATS can also connect to relational databases using Business Logic. With the IBM i, you can also integrate with PCML (Program Call Markup Language) interfaced IBM i apps.
