I am not sure where the term "Data Bean" originated, however, IBM's early WebSphere work, including their Command and Format bean framework, was certainly one of the first technologies to use the term.
A Data Bean, as the name implies, contains only information or data and does not contain any business logic. Data Beans are Java Beans that are typically used as a means to pass data from a controller to a view, such as a JavaServer Page, in an MVC framework. An example of a Data Bean would be a Java Bean that represents a single row in a database table.
