Hi All,

 

i am new to LeanIX, as well to community. i am working on Data flow diagram and having lots of challenges. we have SFTP service which is used by multiple application for file transfer. I added my SFTP application as an application factsheet and added sftp as a provided Interface. below are my questions if anyone can help.

  1. let's assume one application is only sending the file outbound and second file only receive the file incoming, how i can showcase it? in interface factsheet i can select either incoming, outbound or bidirectional. 
  2. If i add an arrow manual (like we add in free flow diagram) we can link to any factsheet like interface etc. For eg. we can add a manual added box to any application factsheet.
  3. is there any way i can get a label based on data flow like inbound file transfer or outbound file transfer based on direction of the arrow automatically.

Thanks

Hi

The approach with having the SFTP-server as an application will create these challenges and remove the ability for end-to-end visibility of interfaces and data flow. Colleagues of mine also had this modeling-reflex (coming from a technical perspective), but it does not create much value from my point of view.

I would go with SFTP (or any other interface protocol / format / technical speciality that is relevant) as an IT-Component and linked to the interface. Because the SFTP-server is not the data provider, it’s just a transfer mechanism.

The data providing and consuming application have an interface (which then can be classified like you described) and that interface has the IT-Component like SFTP added to it.

Like that you have the complete view of information:

  • Which application provides and consumes which data (provider / consumer in the interface)
  • In which direction the data is flowing (direction in the interface)
  • Which technical implementation is used for this specific interface (SFTP, REST, File, etc.)

Cheers
Jochen
