Bases
I think the most important concept to grasp is that with Obsidian Bases you are not creating someΒ _new data_Β with a new Base, you are creating a newΒ _view_Β of your Vault. There is only ever one "database" (the Vault) no matter how many Bases you create, and all of the data lives in the notes themselves, not elsewhereΒ _describing_Β the notes.
