Nosql databases for the .net developer
1 like2,293 views
The document discusses how the database world is changing with the rise of NoSQL databases. It provides an overview of different categories of NoSQL databases like key-value stores, column-oriented databases, document databases, and graph databases. It also discusses how these NoSQL databases are being used with cloud computing platforms and how they are relevant for .NET developers.
Nosql databases for the .net developer
- 3. The Database World is changing
- 6. Data is growing exponentially
- 7. Unstructured data is becoming mainstream in the enterprise
- 8. Fast reads and scalable writes are the norm
- 9. Data mashups are common
- 10. Agility is not an option anymore
- 13. Key value stores
- 14. Key Value Stores • Focus on scaling to huge amounts of data • Designed to handle massive load • Based on Amazon’s Dynamo paper • Data model: (global) collection of Key-Value pairs • Dynamo ring partitioning and replication • Examples: − Voldemort − Tokyo (Cabinet, Tyrant….)
- 15. Big Table Clones
- 16. Big Table • Like column oriented Relational Databases • Tables similarly to RDBMS, but handles semi- structured • Data model: ‣Columns → column families → ACL − Datums keyed by: row, column, time, index − Row-range → tablet → distribution • Examples: − HBase − Cassandra
- 18. Document Databases • Similar to Key-Value stores, but the DB knows what the Value is • Inspired by Lotus Notes • Data model: Collections of Key-Value collections • Documents are often versioned • Examples: − MongoDB − CouchDB − Redis
- 19. Graph Databases
- 20. Document Databases • Focus on modeling the structure of data – interconnectivity • Scales to the complexity of the data • Inspired by mathematical Graph Theory ( G=(E,V) ) • Data model: “Property Graph” ‣Nodes − Relationships/Edges between Nodes (first class) − Key-Value pairs on both − Possibly Edge Labels and/or Node/Edge Types • Examples: − MongoDB − CouchDB − Redis
- 21. NOSQL & Cloud Computing
- 22. NOSQL Cloud Databases • Azure Table Service • Amazon SimpleDB (Dynamo) • Amazon Map Reduce (Hadoop) • Hosted options for NOSQL databases − MongoHQ (MongoDB) − Cloudant (CouchDB)
- 23. NOSQL is not only for internet vendors
- 24. NOSQL Databases for the .NET Developer
- 25. NOSQL in .NET • Key Value stores have been popular in the .NET world for a while − Memcache • Most popular document databases enable .NET interfaces − MongoDB − Redis − RavenDB • Other databases enable interoperable REST-based interfaces − CouchDB − Cassandra • Map Reduce engines have seen slow adoption in the .NET world − Dryad
- 28. Tellago & NOSQL
- 29. Tellago & NOSQL • Cloud implementations using Azure Table Services, Amazon SimpleDB, etc • Logging platform on CouchDB • Notification system over MongoDB • Real time analytics solution using MongoDB and Memcache
