  4. 4. The Definition Data science incorporates varying elements and builds on techniques and theories from many fields, including mathematics, statistics, data engineering, pattern recognition and learning, advanced computing, visualization, uncertainty modeling, data warehousing, and high performance computing with the goal of extracting meaning from data and creating data products.

  16. 16. Data can be accessed easily…
  17. 17. … but, it‘s hard to analyze it.
  18. 18. Other areas of application SOCIAL MEDIA PRODUCT REMOMMENDATION RETARGETING PREDICTIVE MAINTENANCE PREDICT RISKS areas of application SALES PREDICTIONS CUSTOMER ANLYSIS DYNAMIC PRICING DISPOSITION
  19. 19. How does this fit to Big Data?
  20. 20. Our starting point… Structured data Unstructured data Harmonize and generate Information (Role of „Data Scientist“) „BIG Data“ Volume, Variety, Velocity
  21. 21. Typical Big Data Architecture Big Data Analytics Excel Big Data Advanced Analytics PowerPivot Big Data Preparation (SQL, Map Reduce) Unstructured data Structured data Massive Parallel Processing Big Data Storage Platform
  22. 22. “[Facebook] started in the Hadoop world. We are now bringing in relational to enhance that. We're kind of going [in] the other direction.” “We've been there, and [we] realized that using the wrong technology for certain kinds of problems can be difficult. We started at the end and we're working our way backwards, bringing in both.” Ken Rudin, Source: http://tdwi.org/articles/2013/05/06/facebooks-relationalplatform.aspx?j=192038&e=marcel.franke@pmone.com&l=50_HTML&u=3967541&mid=1060748&jb=84&m=1 Director of Analytics for Facebook
  23. 23. Some word to „R“ • R is a language and environment for statistical computing and graphics • R is Open Source under GNU general public license • Most widely used statistical software • Everything happens in-memory • Comes with a package manager (~5000 packages) • Provides also graphical functionalities
  24. 24. Samples of R
  25. 25. How to approach projects?
  26. 26. Starting Point Problems, which we know from the BI world already, are further exacerbated by big data. • Complexity of systems constantly grows • Amount of data growth exponentially (= Big Data) • Need for change is more frequent and is increasingly delving deeper into business rules • Solutions can no longer be thought ahead
  27. 27. Solution Option 1 – Classic Deterministic Everything can be planned and design at the drawing board…
  28. 28. How does a system with products & components and their relationships behaves with each other? Quelle: Cesar Hidalgo
  29. 29. Solution Option 2 – Learn from „mother Nature“ • How does nature deal with complex non-linear systems? • Evolution – Variation and selection – „Trial and Error“ „It is not the strongest of the species that survives, nor the most intelligent but the one most responsive to change.“ (Charles Darwin)
