How to Domain Model – An example from manufacturing

Hendrik Lösch

Programming 25-million-euro machinery is like playing Sudoku on a Rubik's cube. Learn how Domain-Driven Design tames cyber-physical complexities. Isolate hardware dependencies and prevent catastrophic robotic misalignments.

#1 about 3 min

Introduction to cyber-physical systems and software

Combining hardware operations with tailored software enables advanced functionality in massive industrial machines.

#2 about 3 min

Controlling complexity caused by physical product variations

Mixing hardware suppliers and different workflow paths causes a combinatorial explosion of required software logic.

#3 about 4 min

Dividing problem space and solution space with DDD

Domain-driven design separates pure business constraints from technological frameworks to prevent premature implementation bias.

#4 about 4 min

Discovering domain elements using event storming workshops

Modeling reverse-chronological business outcomes and commands reveals natural system interactions without overcommitting to technical details.

#5 about 2 min

Defining bounded contexts for hardware operations

Grouping related physical workflow tasks isolates different subdomains to keep architectural responsibilities distinct.

#6 about 3 min

Resolving ambiguity with clear ubiquitous language terms

Standardizing definitions across interconnected models prevents confusing overlaps between geographic machine layouts and physical component states.

#7 about 7 min

Translating strategic domains into tactical code patterns

Tactical modeling elements like aggregates, entities, and factories encapsulate specific hardware initialization and coordination within the codebase.

#8 about 3 min

Customizing domain patterns for physical hardware states

Extending logic models to include actuators and finite state machines addresses the inherently stateful reality of mechanical systems.

#9 about 3 min

Insulating hardware dependencies via clean architecture layers

Service wrappers and structural abstraction mechanisms allow engineers to swap out proprietary hardware without rewriting core workflows.

#10 about 2 min

Final benefits of relying on strict domain models

Aligning software processes directly with the physical domain limits downstream code breakage when underlying infrastructure changes.
