Clarifications on the difference between Transaction Processing and Event-driven architectural style #343

Closed yienyoong closed 3 years ago

yienyoong commented 3 years ago

Transaction Processing: https://nus-cs2103-ay2021s2.github.io/website/se-book-adapted/chapters/architecture.html#transaction-processing-architectural-style

Event-driven: https://nus-cs2103-ay2021s2.github.io/website/se-book-adapted/chapters/architecture.html#event-driven-architectural-style

After studying these two architectural styles for some time, I am still unable to understand the differences between the two. From what I understand so far, they work the same way just that event-driven is specific to events, whereby events have a certain definition.

Could someone shed some light regarding the differences? If possible, maybe in relation to examples either from the textbook or further examples?

Thank you in advance!

@damithc Thank you so much for the reply.

I think I understand but just to clarify again, the architectures work the same way but one works with events (requiring listeners/observers) and one works with transactions (which exhibit different behaviours from events). Am I right to say this?

Yes. More like the two looks the same, but works differently.

I understand. Thank you Prof!

I will leave this issue open for a while longer for any discussion.
