Normalization of Domain Modeling in Enterprise Software Development

Abstract

Abstract. 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.

The Requirements Enhancement Based on a Problem Domain Model

“…In brief, the concept of Elementary Management Cycle (EMC) [16] is a formalised description of the Enterprise management control as the interaction between the Function and the Process -as two core components of enterprise from the control point of view [17]. The interaction between the core elements a Function and a Process is formally assumed as a Control Process [18] with the Feedback Loop between the Function F(i) and the Process P(j). Life cycle model of the study program content formation as modified Value Chain is presented in Figure 1.…”

Modelling Subject Domain Causality for Learning Content Renewal

“…There are two different systems modelling paradigms: external modelling (a black box approach based), and internal modelling (a grey-box approach and white box approach based) (Gudas and Valatavicius, 2017). The level of awareness of the subject domain is increasing when moving from black-box models towards a grey-box and, finally, to a white-box model.…”

“…Most of the systems modelling methods belong to the external modelling paradigm (Gudas and Valatavicius, 2017). Business process modelling languages BPMN (OMG specification), Data Flow Diagrams (DFD), IDEF, UML, SysML, Event-Process Chain (EPC) based ARIS method designed to describe the results of the external observation, but not internal causation dependencies.…”

“…Transactional workflow refers to a model in which a sequence of interactions goes from one workflow task (step) to another (from one subsystem to another) and back to the first one. A topology of the generalized transaction is a wheel graph (Gudas and Valatavicius, 2017).…”

“…The unified representation (normalization) of captured knowledge is a reasonable condition for comparison of distinct knowledge structures. Normalization in this approach is based on the usage of MT and EMC frameworks (Gudas and Valatavicius, 2017) as the pre-defined causal models of the subject domain.…”
