Receiving Tracking information

When receiving Tracking information, the following steps need to be completed to process the data

flowchart TD
    receiveTracking(["Receive Tracking"])
    findContainerAndShipment["SELECT container JOIN Shipment"]
    updateShipment[/Update shipment\]
    isArrivingSoon{{"Is arrival estimate between now and now + 24h?"}}
    hasArrived{{"Is arrival estimate <=now?"}}
    isDelayed{{Is arrival estimate > original arrival + 24h?}}
    sendNotification[/Send notification\]

    
    receiveTracking -- "`
    **Tracking data**
carrierName:**string**
destinationUnLoCode:**string**
departureDate:**string[_datetime_]**
arrivalDateEstimate:**string[_datetime_]**
containerNumber:**string**
`" -->  findContainerAndShipment
    findContainerAndShipment --> |WHERE containers.containerNumber = :trackingData.containerNumber| updateShipment
    updateShipment --> isArrivingSoon & hasArrived & isDelayed
    isDelayed -->|set delayed flag| sendNotification
    hasArrived  --> |set has arrived flag| sendNotification
    isArrivingSoon -->|set is arriving soon flag| sendNotification
    
%%    isArrivingSoon -->|yes| sendArriveSoon

Possible improvements

• Sending the actual notification, there should be a more general way to setup notifiers
• Moving some variables to config files
  • when is a shipment "arriving soon"
  • database credentials (via an .env)
  • mock date
