Question

Create a PlantUML sequence diagram with the following flow:

• ABC UI -> ABC service -> SU service(TMX)
• ABC service -> EFD
• Option flow: Load Test -> ABC service
• Option flow: e2e Test -> ABC UI

Answer

Here is the PlantUML sequence diagram with the flow:

@startuml
title ABC Sequence Diagram

actor User
User -> ABC_UI: Send Request
ABC_UI -> ABC_Service: Send Request
ABC_Service -> SU_Service: Send Request (TMX)
SU_Service -> ABC_Service: Send Response
ABC_Service -> EFD: Send Data
alt Load Test
    User -> ABC_Service: Send Load Test
    ABC_Service -> ABC_Service: Process Load Test
else e2e Test
    User -> ABC_UI: Send e2e Test
    ABC_UI -> ABC_Service: Send Request
    ABC_Service -> ABC_UI: Send Response
end

Explanation:

• The diagram starts with the User sending a request to the ABC_UI.
• ABC_UI then sends the request to ABC_Service.
• ABC_Service sends the request to SU_Service(TMX) and waits for a response.
• SU_Service(TMX) processes the request and sends the response back to ABC_Service.
• ABC_Service sends the data to EFD.
• The diagram has two optional flows, one for Load Test and another for e2e Test:
  • If it is Load Test, the User sends a Load Test request to ABC_Service, and ABC_Service processes it.
  • If it is e2e Test, the User sends an e2e Test request to ABC_UI, and ABC_UI sends the request to ABC_Service, which sends a response back to ABC_UI.

Here is the PlantUML component diagram with the above information:

@startuml
title ABC Component Diagram

package "User Interface" {
  [ABC UI]
}

package "ABC Service" {
  [ABC Service]
}

package "SU Service" {
  [SU Service (TMX)]
}

package "External Service" {
  [EFD]
}

database "Data Storage" {
  [Database]
}

[ABC UI] --> [ABC Service]
[ABC Service] --> [SU Service (TMX)]
[ABC Service] --> [EFD]
[ABC Service] --> [Database]

Explanation:

• The component diagram shows the components involved in the ABC system, including the ABC UI, ABC Service, SU Service (TMX), EFD, and Database.
• The ABC UI communicates with the ABC Service, which in turn communicates with the SU Service (TMX) and the EFD.
• The ABC Service also interacts with the Database for data storage.
