Sequence diagram for log in3/18/2023 Now the harderdest part, how do I model (4)? Loop doesn't seems right, cause it's not 3 iteration in the same instance of the procedure but three message of the same kind received after a sequence of three different istances. I'm myself very dubious that this goes anywhere near what I'm trying to describe, first of all (1) should be a termination point,the procedure must be restarted by the user, and I can't see how this is shown in the diagram, the same is true for (3), how can I state that the only right flow of events is 1.1, 1.3, 1.4?Īt (2) I've used an entity lifeline because I couldn't manage to find a way to add a message from a lifeline to an entity, in truth I've found that I can't add any kind of messages at all using the sequence tool menu, it only works if I use the recource catalog,to add the second response message I had to duplicate the first and rename it. Three "wrong password" signal cause a security procedure that block any login attempt for 12 hours(4) If the answer is "yes" then an "ok" signal is send to the now logged in user(2)(a different entity that the one which started the operation) otherwise a "wrong password" response is sent to the original user(3). First, we need to head over to the Gleek.io app Select sequence diagram from the dropdown. I wish to draw a sequence diagram for a very classic login operation on a web site: first the user submit a form with a username and a password, the controller check if there is a registered user with that username(1) and then see if the submitted password match the one saved for the user. This video will demonstrate how to make the sequence diagram for a login page. It's my first time working with visual paradigm and uml in general and I'm a bit confused about how I'm supposed to show certain behaviours.
