Introduction to Big Data

Following is the introduction to Big Data slide deck I presented at Colombo Java meetup this month. You can find the slides from Introduction to Big Data. 

Here I am taking a detailed look at the analysis, looking beyond the basic analytics and basic figures. We do analysis for three reasons.

1. To know what happened (Analytics)
2. To  explain what happened (Models, theories)
3. To predict what will happen (Neural networks, Numerical models )

Also the slides discuss much about existing predications like weather we are doing very well. It also includes a typical big data architecture and discusses different parts of that architecture. 

Finally, the slides goes on to discuss Hadoop and CEP and provide some of the examples.
