Class diagrams, when used in conjunction with sequence diagrams, provide an extremely effective communication mechanism. You can use a class diagram to illustrate the relationships between the. Sequence Diagram is an interaction diagram that details how operations are carried out - what messages are sent and when. Sequence diagrams are organized according to time. The time progresses as you go down the page. The objects involved in the operation are listed from left to right according to when they take part in the message sequence. Sequence diagrams show object interactions arranged in a time sequence (refer Figure 5.10). The flow of events can be used to determine what objects and interactions are required to accomplish the functionality. Sequence diagrams are great tools at the start of a project as it shows the user what has to happen in a step-by-step fashion.

SequenceDiagram.org is an online tool / software for creating UML sequence diagrams. Founded in 2014 with the purpose to improve the efficiency when creating and working with sequence diagrams by combining text notation scripting and drawing by clicking and dragging in the same model.

The benefit of this is that SequenceDiagram.org is fast and convenient to work with; it also doesn’t transfer your diagram data over the Internet like many other sequence diagram tools on the market.

The tool is developed, maintained, and used by people who create a lot of sequence diagrams in their daily work. If you have any question / comments / suggestions / bugs please contact info@sequencediagram.org. The more feedback we get the better we can prioritize.
