I do a fair amount of work with Oracle SQL Developer on my Windows 10 laptop, by connecting to my employer's Oracle 19 installation. I have almost no understanding of the PL part of PL/SQL. I want to study PL/SQL in an environment I control completely, not my employer's installation.
Is it a good idea to install an oracle database onto my Windows 10 laptop?
BACKGROUND
I am trying to install Oracle database on Windows 10 in accordance with the prodedure documented at https://www.oracle.com/webfolder/technetwork/tutorials/obe/db/11g/r2/prod/appdev/sqldev/plsql_debug/plsql_debug_otn.htm Oracle SQL Developer is already installed on the laptop
WHERE I AM STUCK
I don't know how to install the oracle database onto my laptop. The instructions at https://www.oracle.com/webfolder/technetwork/tutorials/obe/db/11g/r2/prod/appdev/sqldev/plsql_debug/plsql_debug_otn.htm indicate I need Oracle version 10g with Oracle SQL Developer version 2.1. The version of Oracle SQL Developer on my laptop is 23.1.1.235. I have been unable to find place where Oracle 10g is downloadable.
Any information or advice you can provide will be appreciated immensely.
Thank you.
