Delete objects according to state machine

the following aims to give rules for deleting main objects : person, contract and part

PERSON

A person can be deleted if some conditions are met. The deletion (physical or not) will depend on the status of the person.

1. CONDITIONS

   • it is not contained in another person. For instance a natural person can be member of union => If contained, return no deletion possible.

   • it is not part of a contract. E.g. a person can have a bank account (contract) => If part of a contract, return no deletion possible

   • it has no accounting entries related. A supplier can be stand alone, without any contract but can have accounting entries => If has entries, return no deletion possible

2. STATUS

   Once conditions above have been checked, the deletion will take place according to the status

   • DRAFT : the record can be removed from the DB

   • ACTIVE : no physical deletion possible. The status of the person will be set to : ARCHIVED

3. DIAGRAM

CONTRACT

• BANK CONTRACT

  A bank contract can be deleted if some conditions are met, and also depending on the status of the contract.
  note : a bank contract never triggers change of person status

  • CONDITIONS : the bank contract must NOT be used in another contract (e.g. in a rental contract)
  • STATUS : a physical deletion (only) can occur only if status is : DRAFT

• LEGAL REPRESENTANT CONTRACT (04/2021 : old version, to be updated)

  a legal representant contract can always be deleted
  note : a legal representant contract never triggers change of person status (as of april 2021)
