  • 2. What is this
    session
    About ?
  • 3. OK, actually I will tell you
    Two Important Facts

    I’m interested today in “NoSQL” Concept.
  • 6. so..?
    What is the relationship between

    What does it mean ??
    * Scaling is the ability to enlarge your DB
  • 9. Scalability
    is the facility of scaling
    the system according to
    requirements
  • 10. Types of scalability
    Verticalscalability (scale up) :
    * to add resources to a single node in a system
    * single point of failure
    *easy to be done, because it’s the same implementation only you scale hardware
    Horizontalscalability (scale out) :
    * means to add more nodes to a system
    * No single point of failure
    *complex in implementation
  • 11. Ok, lets get started
  • 12. So, What makes me leave
    MySQL for example and use
    NoSQL?
  • 13. NoSQL features
    that will suitable for
    your needs
    such as ..
  • 14. There is no joins

  • 16. Horizontal Scalable
    architecture
  • 17. New Data Modes
  • 18. Data Models
    Key/value
    memcached , Dynamo
    Tabular
    BigTable (Google)
    Document Oriented
