1. NoSQL Concepts, Redis, MongoDB, CouchDB Svetlin Nakov Telerik Software Academy academy.telerik.com Manager Technical Training http://www.nakov.com

2.  NoSQL Databases Overview  Redis  Ultra-fast data structures server  Redis Cloud: managed Redis  MongoDB  Powerful and mature NoSQL database  MongoLab: managed MongoDB in the cloud  CouchDB  JSON-based document database with REST API  Cloudant: managed CouchDB in the cloud 2

3. NoSQL Databases Overview, Models, Concepts, Examples

4.  NoSQL (cloud) databases  Use document-based model (non-relational)  Schema-free document storage  Still support indexing and querying  Still support CRUD operations (create, read, update, delete)  Still supports concurrency and transactions  Highly optimized for append / retrieve  Great performance and scalability  NoSQL == “No SQL” or “Not Only SQL”? 4

5.  Relational databases  Data stored as table rows  Relationships between related rows  Single entity spans multiple tables  RDBMS systems are very mature, rock solid  NoSQL databases  Data stored as documents  Single entity (document) is a single record  Documents do not have a fixed structure 5
