1. Fast & powerful Scalability and performance Depth of
functionality key/value stores MongoDB RDBMS Focus on performance
{ _id: <document identifier>, key: “value”, subDocument: {innerProp: null} }
JSON/BSON, 16MB Basic types, arrays, embedded documents, ObjectId, other 2. Document-‐oriented
3. Schema-‐free { _id: ObjectId("4B980A6DEA2C3F4579DA141E"), user_id: ObjectId("4B980A6DEA2C3F4579DA4F54"), shipping_address: {

{$lt: 10}} $gt, $lt, $or, $not, $type, $exists, $in, $all, $elemMatch $where – JavaScript expression db.books.find().skip(50).limit(10).sort({name: 1})

fields, Arrays Unique, Sparse, Background Geospatial indexes (2d) db.places.find({loc: {$near: [50,50], $maxDistance: 5}}).limit(20)
Atomic modifiers ($inc, $set, $push…) Upsert FindAndModify Capped collections MapReduce
GridFS 6. Useful features
