Normalization of Domain Modeling in Enterprise Software Development

Normalization has become traditional in database design theory and practice. One disadvantage of the model-driven development is that usage of concepts normalization, and functional dependency in the enterprise software engineering is limited to only one stage of system development life cycle (SDLC) the database design stage. The provided research of these concepts motivate normalization of the entire SDLC. The main part of the paper is devoted to the normalization of the enterprise modeling stage, which is based on the perceived causality of the target domain. The concepts of management functional dependency (MFD) and management transaction (MT) introduced for capturing causal dependencies within the target domain. The first step is the discovery of MFD of business activities. MT is an initial specification of MFD, which gives a basis for enterprise model normalization using the detailed frameworks. Enterprise model normal forms ENF1 – ENF5 defined and illustrated.
