A perspective on Oracle’s development architecture
When I wrote my first PHP book, I felt silly explaining the recursive acroynm because PHP could call HTML and HTML could call PHP. I also included the discussion (misnomer or not) on Paul’s Home Page (PHP).
It struck me when I wrote it that Oracle SQL*Plus environment set the pattern for recursvie call environments. It provided the ability to interactively work with the database or call the database through another program unit (whether internal or external).
You’ll find a diagram that hopefully helps you visualize how Oracle implements SQL*Plus, SQL, PL/SQL, and external libraries in this post.
