webMethods, the company, offers several products. The so-called “EAI” product is webMethods Broker. I assume that’s what you’re referring to. It is a message broker.
webMethods does not have a database product. Rather, it has adapters that can be used to connect to database products from Oracle, Microsoft, IBM, etc. With these adapters, integration solutions can interact with those databases to read and write data.
What specifically do you mean by “…use…as the main database for the trade application?”
