"Big Data"

• Great buzzword!
  • But imprecise when put to action
• Computational performance depends on other factors
  • Computational complexity of methods used
    • Issues for all sizes of data
  • Hardware computing power
    • More machines ≈ more power

"Big Data"

  • But imprecise when put to action
• Definition
  • Small Data - memory
  • Medium Data - single hard drive
  • Large Data - multiple machines, distributed
• Computational performance depends on other factors
  • Computational complexity of methods used
    • Issues for all sizes of data
  • Hardware computing power
    • More machines ≈ more power
