NoSQL Technology is a step back.

• Myth1: NoSQL Technology models Applications more closely than traditional Databases.
  • Data is scattered all over NoSQL land!
  • No (simple) way to ensure various quality domains of data
    • timeliness and appropriateness
    • correctness and consistency
  • Data Integration and Data Quality assurance becomes a full-stack concern!
• Myth2: There are no transactions in NoSQL because transactions do not scale. http://cs-www.cs.yale.edu/homes/dna/papers/calvin-sigmod12.pdf
• Myth3: NoSQL Data Stores are faster.
  • Yes, they are fast. Except the other guys do their homework, too.
