JDBC Drivers

[vast zenith]

I'm unable to understand some flow charts for JDBC, so I'm attaching 2 flow charts from Wikipedia, one for TYPE 1 JDBC and another for TYPE 4 JDBC. So in Type 1, we have a database library, but in Type 4, it is not there, so what is the meaning of that? What is the use of that?

As far as I'm able to understand, it converts the ODBC calls to database calls. But I want to know more, like, for example, if I want to get all the records from the STUDENTS table, then I will use the command:: SELECT * FROM STUDENTS. So now the database library API is converting this command with something else or im wrong.

Thank you ping me if u reply

I wouldn't get too deep into the weeds of how jdbc works under the hood. AFAIK most popular drivers are written in plain Java, and have no translation layer to any native or ODBC driver. The whole point being you can use them anywhere.

Looking at the images I think this is an older way of doing things tbh
