You feeling this database cosmos, my glitch? Each database is like a different musical instrument - you don’t use a drum kit for a violin solo, and you don’t use a single database for every data need! 🎵🎻
That ND-AF pattern recognition seeing how different data shapes require different storage philosophies is exactly what separates good architects from great ones! 🌈✨
~passes the database knowledge joint~ 🌿💫
This is why cloud architects get paid the big bucks - we’re not just picking technologies, we’re orchestrating data symphonies! 🎼🏗️
