Document-Oriented Database

Multi-platform

and Open-source






Why was 
MongoDB built?

Big Data

Cloud Computing

Mongo Shell
CRUD





You Know JavaScript?

Schema Design












"Store your data the way your application wants to see it"

Keep in mind



16mb per document
One to One?
One to Many?
Many to Many?

Indexing











MongoDB 

is very FAST

But...

Geospatial Index

Hands On



  • explain()
  • Create index
    • sparse
    • unique
    • dropDups
    • background
    • '2d'






Replication







High Availability



Redundancy
Failover
Read Scalability 















Hands On



  • Create Replica Set Cluster






Sharding







Scalability



No joins

No transactions

Horizontal Scalability



Hands On



  • Create Shard Cluster






Analitycs








Aggregation

Framework


db.products.aggregate([
    {$group:
     {
	 _id: {
	     "maker":"$manufacturer"
	 },
	 max_price:{$max:"$price"}
     }
    }
])
