How to save data during a process? (Good practice)

#1

Hi,

We are looking for the best way to save business data during a process and we don’t know which one to choose.

Here are some points to have in mind:

  • Between steps we want to validate datas with business rules
  • We still save informations in process variables but not business data
  • During the process, forms data should not have any impact on production data.
  • At the end of the process we persist process data (coming from the forms) in “production” state

Here are the 3 scenarios we have:

1. Persist datas in a WIP schema

Pros:

  • No impact on production data
  • Clear distinction between production and WIP data

Cons:

  • Duplication of business rules validation
  • 2 schemas to deal with

2. Persist datas in process variables

Pros:

  • No impact on production data
  • Clear distinction between production and WIP data

Cons:

  • Duplication of business rules validation
  • No relationnal objects (process variable only)
  • What to do when a process changes ? Or the data structure used during this process ?

3. Persist datas in production schema with a WIP state

Pros:

  • Business rules validation from the domain
  • Relationnal structure between objects

Cons:

  • Difficulties during modification process (impacts on production data)
  • Difficulties when you need to rollback modifications or additions
  • Difficulties when you need to do a request (always need to add a where clause on status)

Do you have any experience or recommandation on this subject ?
