RailsConf – Day 2 – MongoDB Metamorphosis

The MongoDB Metamorphosis: Data as Documents – Kyle Banker (10gen)

http://try.mongodb.com – mini tutorial

MongoDB tries to fit between key-value stores & relational databases

Data as Documents – documents are in BSON (binary json)

mongoDB operates on documents using special syntax

update() takes a query and an update (what to do) .. the update is applied to the results of the query

Embedded documents – i.e. Comments become embedded within Posts
Or you can normalize – Post id within each comment
Decisions to be made on what makes most sense for how you need to access the data

Embedded – fast queries, document always appears with parent

Hash is the object used to represent MongoDB objects

MongoMapper

Very informational, I want to try using this!
