> If you're EVER going to read the data back and do anything with it, it has a schema.

You are giving the NoSQL crowd too much credit. Some abominations have no recognizable schema at all. The data store will just contain arbitrary dump of data which different developers decided their "schema" should be. The number of "columns" will vary, the "columns" will have arbitrary formats, so on and so forth.

If one developer decided to separate name into "first: John", "last: Doe", you will have that. If another decided to have "name: John Doe". That's what will be there. If one developer decided social security should be "SSN: 123-45-6789" and another decided it should "SSN: 123456780", well you are going to have fun cleaning up the data at the business or even application layer.

But that's not even the big issue with MongoDB. It's their lack of ACID compliance!
