Sequence Diagram Templates and Examples.In this sequence diagram tutorial you will learn about Among the three, sequence diagrams are preferred by both developers and readers alike for their simplicity. These diagrams are used to illustrate interactions between parts within a system. There are 3 types of Interaction diagrams Sequence diagrams, communication diagrams, and timing diagrams. I have more productivity hacks on the website – you can start at this page if you like.This sequence diagram tutorial is to help you understand sequence diagrams better to explain everything you need to know, from how to draw a sequence diagram to the common mistakes you should avoid when drawing one. I hope this helped you speed up your day. Nice to get the code to do the heavy lifting! Conclusion See how I’ve added a note, and deleted irrelevant classes, all through a nice GUI. This original diagram has a lot going on:īut now it’s in PlantUml format on SequenceDiagram, it’s easy to modify. With that PlantUML file saved off to my file system, I have a template I can then load it into and change my diagram to suit my needs.

Luckily, as well as generating images for export, it can also export to PlantUML, which is a format used by the popular website. I don’t want every single low level detail, and I want to be able to add notes where needed, change class names in the diagram etc. I want better control over the sequence diagram from my code. However the sequence diagram plugin can generated quite ‘noisy’ output initially. The problem is, I want to show some, but not all of the AWS operations to my colleague. Later I’ll use to add notes, and remove superfluous classes to make my point clearer.

Here I’m illustrating a concept from the AWS DynamoDBLocal libraries to a colleague using the Intellij Sequence Plugin. To start with, I can use the popular IntelliJ Sequence Diagram plugin. For example, I have a new idea for something, but it’s quicker to use existing code to create the high level components in Intellij. Sometimes you just want something to do the grunt work, which you can refine later. Then you can use a better editor to refine the content you wish to share with your colleagues. The sequence diagram plugin is the best way to stay within Intellij to generate the first cut.

A useful combo for using the IntelliJ Sequence Diagram plugin to generate sequence diagrams and then handing off to an online editor.
