Colour Modelling - domain modelling with the 3rd dimension
- 1. Colour Modelling Modelling with the 3rd dimension by Doug English Co-founder & Head of Engineering @ Culture Amp
- 2. Object Oriented Modelling asks us to focus on ‘real world objects’ Aeroplane Passenger Flight Plan Airport
- 3. and their relationships * * Aeroplane Passenger * 1 * * Flight Plan Airport
- 4. but temporality causes us issues * * Aeroplane Passenger current historical * 1 * * 1 1 Flight Plan Airport
- 5. but temporality causes us issues * * ? Aeroplane Passenger current historical * 1 * * 1 1 Flight Plan Airport
- 6. and the more concepts we add the messier things get AirHost Pilot Customs Aeroplane Passenger Flight Plan Airport Luggage Hanger Airline Itinerary Country Ticket RunWay (Admit it, we’ve all seen domain models worse than this!)
- 7. my background Consulted as a Domain Modeller with large scale industry models (eg IFW, OFX) at multinationals (NAB, ANZ) Mentored by Jeff De Luca (Architect of Feature Driven Development) 5 years of experience applying and adapting my learnings to startups
- 8. what I’ve learned You can’t model a domain you don’t understand. It’s critical to work hand-in-hand with domain experts!! Don’t try and model the “entire” domain. Model only what your solution needs to care about. Your domain model must be the share language between all stakeholders - and used to name classes in the code!!
- 9. Colour Modelling categorises everything into one of 4 archetypes << party, place, thing >> << party, place, thing >> << description >> Description Party, Place, Thing << role >> << << moment-moment-interval interval >> >> Moment- Role Interval (They’re all ‘real world’ just some are ‘concepts’, not ‘objects’)
- 10. that tend to connect consistently << party, place, thing >> << party, place, thing >> << description >> Description 0.. * 1 Party, Place, Thing 1 0.. 1 << role >> << << moment-moment-interval interval >> >> Moment- 0.. * 1 Role Interval
- 11. and tend to have similar attributes << party, place, thing >> Description << description >> << moment-interval >> Party, Place, Thing Moment-Interval 0.. * << party, place, thing >> identityNumber name customValue getCustomValueOrDefault listRoles accessAcrossRoles << << role role >> >> << moment-interval >> Role 1 description itemNumber defaultValue listPPTs findAvailable calculateTotalFor assignedNumber status isAvailable listMIs assessAcrossMIs referenceNumber dateOrDateTimeOrInterval status addRemoveDetail calculateTotal complete 0.. 1 0.. * 1 1 << moment-interval >> << mi-detail >> << momentM-inI-tDerevtaali l>> quantity calculateTotal 0.. *
