3. Copyright © 2014 Oracle and/or its affiliates. All rights reserved. | Agenda A bit of history and what is NoSQL Data Model Architecture Consistency When to use Community Edition vs Enterprise Edition What’s new in release 3.0

4. Copyright © 2014 Oracle and/or its affiliates. All rights reserved. | Reasons for creating NoSQL technology The appearance in the early 2000s: •Google - web search engine •Facebook – social network •Amazon - online retailer Common features of these systems: •Constantly changing structure •Unpredictable data growth •A huge number of users

5. Copyright © 2014 Oracle and/or its affiliates. All rights reserved. | What is NoSQL? NoSQL = Not only SQL. Do not have a structured scheme -Frequently the data is stored in the scheme of key-value -The structure of the database schema is created by the application Allow almost infinite horizontal scale -The data is stored in the copies on different servers -Node failure does not result in data loss -Reading is done from the master or a copies Working with data through a simple operations (no SQL) -CREATE -RETRIEVE -UPDATE -DELETE

7. Copyright © 2014 Oracle and/or its affiliates. All rights reserved. | Oracle NoSQL Database Horizontally Scaled, Key-Value Database for Web Services and Cloud •Simple Data model Based on Key-value scheme with two parts key – major + minor Simple operations read/insert/update/delete •Scalability Optimized data access Smart division and distribution of data •High Availability & No-Single Point of Failure single-master, multi-replica database replication automated fail-over election •Transparent Load Balancing Read from master or/and replicas Network topology and latency-aware Storage Nodes Data Center A Storage Nodes Data Center B Application NoSQL DB Driver Application NoSQL DB Driver

8. Copyright © 2014 Oracle and/or its affiliates. All rights reserved. | Key – Value pair Oracle NoSQL Database hashes keys to provide good distribution over a collection of computers that provide storage for the database. A key is the concatenation of a Major Key Path and a Minor Key Path, both of which are specified by the application. A minor component does not affect the distribution and can be empty. Key

9. Copyright © 2014 Oracle and/or its affiliates. All rights reserved. | Key – Value pair Oracle NoSQL Database stores value as byte array. Mapping of the byte arrays to data structures is done by application. There are no restrictions on the size or structure of the value field. Value

17. Copyright © 2014 Oracle and/or its affiliates. All rights reserved. | Consistency of data BASE Basically Available Soft state Eventual consistency ACID Atomicity Atomicity requires that each transaction is "all or nothing": if one part of the transaction fails, the entire transaction fails, and the database state is left unchanged. Consistency The consistency property ensures that any transaction will bring the database from one valid state to another. Isolation The isolation property ensures that the concurrent execution of transactions results in a system state that would be obtained if transactions were executed serially, i.e. one after the other. Durability Durability means that once a transaction has been committed, it will remain so, even in the event of power loss, crashes, or errors.

18. Copyright © 2014 Oracle and/or its affiliates. All rights reserved. | Consistency of data Oracle NoSQL Database – ACID or BASE system? Can be configured for the whole system and for a particular operation!

19. Copyright © 2014 Oracle and/or its affiliates. All rights reserved. | In which case you should use Oracle NoSQL Database?  Terabytes or petabytes of data  The application should not have a single point of failure  The use of multiple low-cost servers  Short response time of simple queries  Unstructured or semi-structured data model

20. Copyright © 2014 Oracle and/or its affiliates. All rights reserved. | Potential systems for Oracle NoSQL Database  LDAP like systems Why? It’s fast! User personalization Why? No clear data model and constant addition of new features! Collection of different types of data from the sensors Why? A lot of concurrent sessions! Logging of Internet traffic (CDR GPRS, web logs) Why? Huge amount of data! File storage (like Dropbox, Google disk) Why? Cheap store of large amounts of unstructured data!
