Do We Give Examples of Not All Applications That Need Transactions?

The book has made me like all the things that I've taken for granted for years related to, you know, my use of databases. And now I'm like, okay, well, how might I implement this? But what happens in that case where like, let's say,  you might have six tables, I think was your example. So yeah, talking about like, do we give examples of not all applications that need transactions? Nah, I haven't talked about that yet. Like just imagine how long these stock tickers have been online. There's no way they're tracing these movements every day and, and retaining it for years on end. They can't be.
