Part 1 of 3 - Transitioning Use Cases into a Context DFD into a System DFD

What if you have many actors, what should i do?

In the video, there are many Actors. Customers and Hotel Staff are both Actors.

@@carusonj what i mean,is more than 2.. like 5 actors,and those actors have different use cases, they don't have duplicates. How can i turn it to a DFD?

@@skyenicholas6900 In the video, at 4:54, you can see the use case $5. Receive Confirmation only goes to the Customer. The Hotel Staff does not get that Use Case. You can have N number of Actors, with some of them sharing Use Cases, and some of them (like use case #5), only going to one Actor. You can have a new Use Case #8 Generate Sales Reports that goes to a new Actor = Hotel Executive. So it would be Hotel Executive -> #8 Generate Sales Reports.

How did create the diagram objects?

I've just started teaching this course. Looking at the best ways to share info with students. I use PPT for these. In professional settings I'd use Visio, but most people now have access to PowerPoint which makes it easier to share and use.
