This UML sequence diagram for Netflix shows how users interact and how their actions correspond to those of streaming services like Netflix. It begins with a user opening the app, signing in, and searching for content. The server that performs authentication checks user access data; meanwhile, the content server responds with media desired by users. The model contains valid and invalid login paths; some media options can be displayed afterward when someone selects them for streaming. If someone logs in incorrectly, they will receive an error message.
