MEAN Vs. LAMP: Finding the Right Fit For Your Next Project

snydeq writes: LAMP diehards take note: The flexible simplicity of MongoDB, ExpressJS, AngularJS, and Node.js is no joke and could very well be a worthwhile stack for your next programming project, writes InfoWorld's Peter Wayner. "It was only a few years ago that MongoDB, Express.js, AngularJS, and Node.js were raising eyebrows on their own. Now they've grown up and ganged up, and together they're doing serious work, poaching no small number of developers from the vast LAMP camp. But how exactly does this newfangled MEAN thing stack up against LAMP? When is it better to choose the well-tested, mature LAMP over this upstart collection of JavaScript-centric technologies?"

So much stupid

Among the great revelations of relational databases was the JOIN command. With JOIN, we could save disk space by removing repeated fields like city, state, and ZIP code. By storing this frequently accessed and repeated data in separate tables that can be included in future results through a JOIN, we keep our database tidy and our disks slim. But JOINs can be tricky for some and hard on RAM, and though it's still a good idea to isolate and access data in separate tables through JOINs, there's not as much need to save disk space now that disk drives are measured in multiple terabytes. The space is so cheap that some database designers end up denormalizing their data because the JOINs are too slow.

This is just so wrong. If you store, let's say, city/state/zip redundantly, then you run the risk of having the copies, that should be kept synchronized, diverge. This is especially true in the absence of all-or-none transactions. And not to mention the fact that having to update the "same" datum in multiple places is going to affect performance.
