Schema-agnostic databases

Schema-agnostic databases are special kinds of databases that don't require you to decide on the design (or "schema") of the data you want to store before you save it. This means that you can just store data, no matter the type or how it's structured, and you don't have to think about the structure until you actually want to use the data. This makes it easy and fast to save data, and much more flexible for when you're not sure what type of data you might need to save.
