LAYERING OF BUSINESS OBJECT MODELS VIA EXTENSION TECHNIQUES

摘要

An extension node can be defined in a second layer of a software architecture for a first business object existing in a first layer and originally having an association with a second business object that is also in the first layer. The extension node can be defined to have an association with the second business object existing in a second layer of the software architecture. The association of the second business object can be altered from the first business object to the extension node so that at run time, metadata defining one or more nodes of the first business object and the extension node can be read from a metadata repository and a run time version of the first business object can be constructed at run time in a run time business object load based on the metadata.
