This document discusses trends in big data, including what big data is, how it is used, and its impact. It notes that big data refers to large volumes of diverse data from sources like social media, sensors, and scientific experiments. Examples are provided where analyzing big data in real-time has provided insights, such as how sensor data helped a sailing team optimize performance. The document also discusses how big data is changing organizations to be more outwardly focused and responsive to customers, and how IT systems need to integrate big data with traditional data warehouses and business intelligence tools to provide fast access and answers.
6. Big data: what is it (or not)
• Social data.
• Sensor data.
• unstructured data.
• A hype
• Hadoop
• Real-time
• ………………
• The four V's: Volume, Variety, Velocity, Value
9. Wat exactly is the trend ?
• “a lot of data” isn’t new:
• Governments
• Stock exchange.
• Real-time isn’t new:
– Railway management
• Level of detail increases
• Data is no longer in possession
• Open Data intiatives.
10.
11. Example 1:
on-board sensor data
• America’s Cup 2013
• On-board sensors
• Off-board sensors
• 30.000 dp/s
• Oracle Team USA won 9-8 after 8-1 down, because of ‘insight’.
12. Example 2:
medical
• personalized healthcare
• n=1 treatment.
• Bring down cohort-size by
means of more personal
data.
17. Value of data
• The higher up in an
organization, the lower the
value of an individual
datapoint.
• The lower (more operational)
in an organization, the higher
the value of an individual
datapoint.
• Big data offers more (real-time)
insight on
operational level than on
strategic level.
18. • Big Data is mainly a CX ‘thing’.
• 360-degree view of
• Patient
• Customer
• Supplier
• …
• …
28. Datawarehouse, Big Data and Business Intelligence
– Storage of Big Data: Hadoop
– Storage of ‘traditional’ data: RDBMS
– necessity: transparant access.
– necessity: high-end usertools: Self Service BI.
– necessity: fast back-end.
32. Conclusions
– Big Data
– Large Volume (Volume)
– Fast (Velocity)
– In different shapes and sizes (Variety)
– Huge information potential (Value)
– Data grows exponentially
– Data is extern
– Data must lead to faster insights
– Fundamentallly datawarehouse redesign
– In-memory
– Demands organizational changes
Editor's Notes
Opmerkelijk: dit gaat over aantallen, over groei.
Detailniveau wordt groter: “Logistiek voorbeeld: waar is de vrachtwagen nu ?, versus aan het eind van de dag een bon afleveren.”
72.000.000 datapunten per race.
