FAQ / examples of supported local data stores?

I am learning iOnic and using Creator.
Is there an FAQ or some examples on how the following (these are core to ANY real application):

  • What databases / object stores are supported ?
  • Do you have examples ?
  • How do I upload a pre-populated datastore from my machine to use in Creator ?
  • What is the best way to initialize a datastore in an iOnic / Creator app ?

Thanks in advance for any help you can offer,
Stephen
