Transcript of NoSQL Controversy
30 years of standstill
Big database vendors and DBAs ruled
People forgot how to build databases (cf. prohibition in the USA, http://blog.8thlight.com/uncle-bob/2012/05/15/NODB.html) History repeates itself:
"[Teradata]'s very similar to the Tandem story: it's a sort of one-trick pony. It doesn't have referential integrity; it doesn't have all the fanciness. You give it SQL; it gives you back the answers, very fast, and presumably cheaply, because it's running on Intel processors and on commodity disks." http://www.mcjones.org/System_R/SQL_Reunion_95 Ted Neward (2004): "Object-Relational mapping is the Vietnam of our industry" https://twitter.com/DEVOPS_BORAT http://crudcomic.com/image/9606986184 Schema changes get easier
At least at first
Schemaless development is great
Schemaless ops are a nightmare Polyglott persistence is great
If you can handle it "Nobody gets fired for choosing IBM" http://xkcd.com/327/ RDBMS: What answers do I have?
NoSQL: What questions do I have? You don't always need multi-document transactions,
Different structure (embedded documents, arrays)
Add entity or do cleanup -> try-catch on unique attribute http://geekandpoke.typepad.com/geekandpoke/2011/12/the-hard-life-of-a-nosql-coder.html Application- vs data-view,
who is the gatekeeper? http://crudcomic.com/image/10538412809 "KnowSQL is the new NoSQL" Philipp http://browsertoolkit.com/fault-tolerance.png
