Declarative Business Logic - Seperate project: rulez.io #8

Open 0xgeert opened 11 years ago

Similar to #7 (discussing controllers), would it be possible to have declarative business logic? Especailly when we have a notion of a declarative workflow a lot should be possible. (where leaf-nodes should result on repo-actions)

e.g: the following should be possible:

Domain Model: Fat model with business logic, operates on a single or multiple data entities (i.e. entity A in a given state than action on entity B)
Data Model: Storage-aware model, logic contained within a single entity relates only to that entity (i.e. if field a then field b) -> EAGER CALCULATED FIELDS. (lazy would be on RESOURCE, i.e: calculate JIT)

Some 'halfway there' thoughts:

declarative business rules (rule engine / inference engine / expert system / business process management)
can all business logic be defined as business rules?
- search for "rule engines" and DDD to check if DD pees thinks rule-engines are enough.
- HINT: they don't. But I'm not sure the're right.

More general: workflow implementations in NODE

If you are building a completely new system composed of many discrete API applications, each of them with a clearly defined area of responsibility, or if you are trying to assemble a collaboration channel between a heterogeneous set of unrelated API applications, you need a means to orchestrate interactions between these applications.

MACHINA.JS looks like a nice basis for RULEZ.io

noflo

i.e: fsm for business logic?
