There are thousands of big data tools out there for data analysis today. Data analysis is the process of inspecting, cleaning, transforming, and modeling data with the goal of discovering useful information, suggesting conclusions, and supporting decision making. To save your time, in this post, I will list out 30 top big data tools for data analysis in the areas ofopen source data tools, data visualization tools, sentiment tools, data extraction tools and databases.
Open Source Data Tools

For each topic you get a pie chart showing current real-time sentiment, a list of the latest news headlines, a few thumbnail images, and a tag cloud of key semantic concepts that the public associates with the subject. The concepts allow you to see what issues or events drive the sentiment in a positive or negative way.
