Connecting oracle with unity tutorial, Steps or a way?

is there no tutorial or anyway to connect unity with oracle database?
searched & googled for how to do it so many times and found Only 4 to 6 links with no answers or tutorials.

is it even possible to connect unity with oracle :`(?

What’s wrong with, for example:

using Oracle.DataAccess.Client; 
...
OracleConnection con = new OracleConnection();
con.ConnectionString = "User Id=scott;Password=tiger;Data Source=oracle";
con.Open();
