Abstract
Constructing reliable enterprise software systems remains one of the most difficult problems in Software Engineering. Our experience is such that from the engineering perspective this is attributed to an impedance mismatch between software architecture at the micro (objects) and macro (system components) levels, and from the utilisation perspective -- to an impedance mismatch between the business domain model and its perception by different system's stakeholders. We argue that these two factors are related, and can be resolved at the level of information systems architecture. Fractal Objects is an approach to software architecture with the domain orientation and holistic object-oriented architectural style at its core. It formalises a way for designing and provides technical means for constructing resource-oriented software systems with a transparent domain (ontological) model. The domain model transparency empowers all system stakeholders (including end-users and developers) to better utilise and support evolution of an enterprise software system.
