If you design complex systems, you'll love sequence diagrams
Complex system architectures can quickly become tangled and hard to follow. Enter sequence diagrams! They keep your design neat and easily understandable.
For example, check out the diagram below. It depicts a client/server interaction, clearly differentiating between a cache hit and a cache miss. This is a prime example of how visual aids simplify complex interactions.
Sequence diagrams are a must when you aim to:
- Map out end-to-end system workflows.
- Clarify interactions between components.
- Produce clear and concise documentation.
- Identify design flaws.
I have two favorites for creating sequence diagrams. WebSequenceDiagrams and Mermaid (links in comment). You can make sequence diagrams easily with just text.
Do you have a go-to tool for crafting good-looking sequence diagrams? Drop your suggestions below!
