Big Data-Scenario 1: Iterative Data Exploration
A common big data analysis scenario is to explore data iteratively, refining the processing techniques used until you discover something interesting or find the answers you seek. In this example of the iterative exploration use case and model, HDInsight is used to perform some basic analysis of data from Twitter.
Social media analysis is a common Big Data use case, and this example demonstrates how to extract information from semi-structured data in the form of tweets. However, the goal of this scenario is not to provide a comprehensive guide to analyzing data from Twitter, but rather to show an example of iterative data exploration with HDInsight and demonstrate some of the techniques discussed in the patterns & practices "Developing Big Data Solutions on HDInsight" guide.
