Conclusions

Review the decisions behind the case studies: how data is identified and stored, which work can be asynchronous, and what the user observes when a dependency fails. Use the comparison below to choose a problem for deliberate practice.

You have reached the end of the full-length design sequence. The case studies offer different ways to practice the same reasoning skills, not one architecture to reuse unchanged.

We explored System Design through the lens of basic building blocks. This approach allowed us to focus on specific business use cases without repeating recurring concepts.

We selected design problems from diverse domains. Each problem highlights unique aspects and challenges of System Design.
