3. Why MongoDB?
• Popular 
• Easy to use nosql
• Good for web projects
• High performance (No joins and embedding
makes reads and writes fast)
• High availability (Replicated servers with
automatic master failover)
• Easy scalability (Automatic sharding)

4. RDBMS => MongoDB
RDBMS MongoDB

6. Official C# Driver

7. Connecting to MongoDB
• If DB does not exists driver will create one for
you
• http://www.mongodb.org/display/DOCS/CSharp+Driver+Tutorial#CSharpDriverTut
orial-Connectionstrings
• mongodb://[username:password@]hostname[:port][/[database][?options]]

8. MongoCollection

9. What is BSON?
• MongoDB uses BSON as the data storage and
network transfer format for "documents".
• Short for Binary JSON
• http://bsonspec.org/
• http://www.mongodb.org/display/DOCS/BSON

10. Working with POCOs
• Things can be really easy for you if you follow
these rules for your pocos
– Has a public no-argument constructor
– Has a public get set property for each value you
want to have serialized

11. Let’s add the first item

12. Let’s find (Query) it

13. Demo

14. Creating indexes for performance

15. A tip for better indexing
• Run mongodb with notablescan parameter
and be sure your your queries are not making
full table scans...
– You get exceptions if a query needs a table scan,
it gives you a chance to fix your indexes on
development time.
