I often use query's to pull in datasets into my components, and wanted to know where are these datasets being stored in ignition?

I ask because I want to know is it possible to create a dataset somewhere in the designer outside of the components, and then call it later into a component ?

Just in java memory, as long as some property somewhere references them. Or they are referenced by a long-lived variable in a project script module.

Yes, this can be done with project library scripts. Commonly with `system.dataset.toDataSet()`.
