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.

    I don’t think many businesses use MySQL when they can use PostgreSQL. Oracle is used very often. MSSQL in stupid cases.

    You obviously need databases to, eh, store data, index it, process it, access it.

    Also, as others say, it’s a wide concept. A file system is a database. In some sense BitTorrent DHT is a database.
