Hi, I have a couple of sqlite dbs (i'd say about 15GBs), with about 1m rows in total - so not super big. I was looking at mongodb, and it looks pretty easy to work with, especially if I want to try and do some basic natural language processing on the documents which make up the databases. I've never worked with Mongo in the past, no w...

I am currently in a personal learning project where I read in an XML database. I find myself writing functions that gather data and I'm not sure what would be a fast way to return them.
