How to use database on Safe?

@happybeing Thanks for the tips. Anyway I have 2 problems:

  1. The Safe Web API code link which you gave is showing that page not found.
  2. In the SAFE Network API page, there are a few webapp example that demonstrates to do several things. However, where do I place the code for it to work? Is there anything I need to download first?
    Sorry that I may asking some simple questions but I am a totally beginner of doing this. Hope you can help!
