We prepared a small 30 min workshop for the Dutch Java User Group to introduce MongoDB basics. This slideshow contains the mongoDB concepts, which will be workout basic in labs . The labs could be found at: http://mongodb.info/labs/

1. db.NLJUG.insert(
{ “presenters” : “Maikel Alderhout & Bas van Oudenaarde”,
“type” : “JFALL”,
“datum” : ISODate(31/10/2012) } )

2. NoSQL Hype
• Not only ... of No SQL
‘not only’ relationele data opslag

3. Database evolution #1

4. Database evolution #2

5. Database evolution #3

6. De huidige trends hebben een behoorlijke impact in het
traditionele database landschap

7. Hoezo Java problemen?
• Schaalbaarheid 3-tier architecturen
• ORM, mapping vanuit domain objecten.
Lekker alles aan elkaar knopen
• Caching, niet te veel naar de database
• Alles in memory, dan maar?

8. NoSQL oplossingen
Key-Value Column Document G
Key-value store Document
bv.Voldemort, Dynomite, Tokyo bv CouchDB, MongoDB, Riak
ColumnFamily /
Column Document
BigTable clones Graph Graph databases
bv Google BT, HBase, Hypertable, Neo4J, Sones, AllegroGraph
Cassandra

10. MongoDB is a scalable, high-performance NoSQL
database.

11. JSON Document
Person

"group" : [ "Open Source", "mongoDB", "Big Data" ]
}

12. Replication
Sharding
Durability

13. Replicatie
read
read/write
Asynchronous
Replication
read
Automatic election
of new Primary

14. Sharding

16. Sharding features
• Automatic partitioning
• Automatic Load-Balancing across shards
• Range-based
• Convert to sharded system with no downtime
• Fully consistent
• Application code unaware of data location
• Zero code changes

17. Durability
