Application object model for engineering information systems

Abstract An object model for application development is introduced in the context of Engineering Information Systems (EIS) 1 . The model shares features with several popular models and offers some less common ideas, such as operation-dependent state closure. The model is also unique in its position within the environment: it acts as a portability view independent of the underlying storage servers. The view-mapping is made most efficient however, if the object model of the underlying servers matches the structure of the EIS Application Object Model (AOM).
