Abstract: A software customization framework based upon an enterprise platform comprises a metadata framework, a service layer, and an object layer. The metadata framework comprises a generic domain class. The generic domain class defines one or more extension classes. The service layer receives one or more requests from a client and processes the requests via a dispatch service which forwards a call to a generic executable object. The object layer generates the generic executable object at run time. The generic executable object uses the extension class to identify data, an operation, and a select dispatch scheme. The generic executable object also invokes a handler responsive to the call. The handler uses the select dispatch scheme to implement a desired operation in the data structure responsive to the data and the operation from the executable object.
