I am very curious as to how databases are used in the real world, whether you’re using MySQL and what not, how does it all come together in a real world business? Banking and gaming I know, but is it something that gets stored on data centres and then put into a VM?
I might be overcomplexing this but I understand the good use cases with VMs and containers etc just not with databases.
I’d google, but I’d like a ELI5 due to my smooth brain with these concepts, thank you.
If I understood your question correctly,
A database is a base for your data, its where your data lives.
A data is the most important thing for most modern applications. You have an account in Lemmy. You have made posts and comments. All that post texts, images, etc has to be recorded somewhere in the server. Thats what a database does.
