Principles

All development MUST follow the following principles:

• DDD

• CQRS

• Event sourcing

  • One event stream per aggregate instance (minimises contention with positive locking)
  • Events from Event Sourcing (Source Events) SHALL NOT be shared externally
  • Only Domain Events are available to klients

• Privacy by Design

  • PII is stored only one place
  • New PII uuids are generated for each shared context of aggregate roots (aka. Incident)
  • Only PII uuids are stored in streams
  • PII CAN be stored in memory in Aggregate roots (lookup from PII context using uuid)

Aggregates

• Tenant
  • AppConfig
  • BaseMap
• Incidents
  • Subjects
  • Clues
• Operations
  • Objectives
  • Missions
  • Units
  • Allocated Personnels
  • Allocated Transports
• Tracking
  • Devices

• Personal Identifiable Information (PII)
