It all leads to logic
-(Doctor Who, The Wheel in Space, 1968)
-(Doctor Who, The Tomb of the Cybermen, 1967)
And so, we come to the most important tool to connect all these systems together –logic apps.
The Microsoft Azure Logic App is an example of no-code development. The idea is that a non-technical person who has not learned a programming language can still produce logic in much the same way that a business analyst may structure a sequence of events in a Visio flowchart.
Note
Sadly, I once lost a government teaching contract due to the change toward no-code development. I delivered a Visio training course and mentioned that the aim for Microsoft was to allow non-programmers to create program code. The initial idea was that a Visio diagram of an application would contain logic, and that could be turned into a skeleton of modules and functions within Visual Studio.
Not so far out. The eventual product was Logic Apps.
