Create a uml sequence diagram.
Login uml state diagram. Type a name for the action. Use pdf export for high quality prints and svg export for large sharp images or embed your diagrams anywhere with the creately viewer. I m particularly interested in your use of design patterns and which patterns you would use how you. State machine diagrams can also be used to express the usage protocol of part of a system.
Use a state machine or statechart diagram to show the sequence of states an object goes through during its life. In the uml state properties dialog box click entry or exit and then click new. Choose the action type you want and then click ok. Example state diagram for an online order figure state diagram for an online order.
Using our collaborative uml diagram software build your own state machine diagram with a free lucidchart account today. A behavioral model comprising actions and states or state transitions the diagram provides for an initial and final state and at least one intermediary state for each object within the model. On a statechart diagram or activity diagram double click the state shape you want to add an entry or exit action to. The object can be a computer program device or process.
A state diagram sometimes known as a state machine diagram is a type of behavioral diagram in the unified modeling language uml that shows transitions between various objects. Two kinds of state machines defined in uml 2 4 are. I m sure its a poor design and full of flaws but i m hoping to learn from you guys how you would design a simple login like this.

Here is just an example of how an online ordering system might look like. The uml diagrams we draw depend on the system we aim to represent. On the event of an order being received we transit from our initial state to unprocessed order state. State machine diagram is a behavior diagram which shows discrete behavior of a part of designed system through finite state transitions.
The diagram below is my very first attempt at creating a uml class diagram describing a user login into a website. Use an activity diagram to describe the internal behavior of a method and represent a flow driven by internally generated actions.
