business object
A business object is an entity within a multitiered software application that works in conjunction with the Data Access and Business Logic Layers to transport data.
==Function==
Whereas a program may implement classes, which typically end in objects managing or executing behaviors, a ''business object'' usually does nothing itself but holds a set of instance variables or properties, also known as ''attributes'', and associations with other business objects, weaving a map of objects representing the business relationships.
A domain model where ''business objects'' do not have behaviour is called an anemic domain model.
Business objects separate state from behavior because they are communicated across the tiers in a multi-tiered system, while the real work of the application is done in the business tier and does not move across the tiers.
