Get a database
You need an oracle, mysql, or postgres database with a user/pass where the user can do whatever they want in their schema (e.g. create tables)
Well, for this example, might as well go from scratch in aws, but this could be on prem or wherever. Create a free-tier database in AWS. Mysql RDS, publicly accessible.
RDS → Create database → Standard create → MySQL → Free tier → T2 micro → 20g → publicly accessible
Allow from everywhere (just for poc)
Create a database, user, and pass with sqlyog (or whatever db client)
Note: maybe your DBAs will do this for you
Allow user to access database
