Business entities are the basic building block of Framework applications. They encapsulate the business data as defined by the fields and present the data to the user in a panel.
Business associations are the links between business entities. They allow data to be related to each other, and easily be associated and disassociated. They are defined as foreign key relationships in the database.
Framework business events are ways to add custom actions to your application. A business event is generated whenever an event external to the system occurs (e.g., a user clicks on a button, an external device signals that a message has arrived, or a scheduler signals that it is time to do a backup).
