Abstract
Software is often constructed using a layeredapproach to encapsulate various functionality in correspondinglayers. Individual requirements of each layer demandlayer specific data structures. These data structures typicallyprovide redundant information with respect to the datasource.Providing a Model Driven Software Development approachfor creating these data structures leads to overlappingdata models, each containing data structures definedby the data source. Because putting all various requirementsof the software layers in a single data model can leadto difficulties, each software layer should only extend thebasic data source model with its specifically needed modelelements.The approach presented in this paper applies a mechanismfor a dynamic extension of a data model. Thisextension mechanism is used in the implementational activityof a software process, and allows the changing of a modelwithin a local scope. Using this mechanism, a basic datamodel can be used by every layer, being extended byadditional attributes and classes for satisfying layer specificrequirements.
