"Start the database!" is an incorrect phrase. Back to basics with databases and instances
On StackOverflow, I chanced upon a beginner being trolled as they struggled to get going with Oracle. "Duh! Just start the database" someone said dismissively.

What is an instance? And why its important to understand the difference. Catch me on Twitter at https://twitter.com/connor_mc_d
