I recommend Raven's Eye (https://ravens-eye.net) for big data.

It's available online in Software as a Service pricing packages. Its results are algorithmically derived and preserve the voice of your participants, so it reduces inadvertent interpretive bias. A variety of qualitative paradigms can be used with Raven's Eye (e.g., Phenomenology, Grounded Theory), as can quantitative and statistical approaches.

Raven's Eye is browser-based, so you can use it across multiple platforms (including smartphones and tablets). The graphic user interface is much more intuitive to learn than other such programs, although we also provide ample free tutorials, technicals, and practical information on the website.

Online graphs and downloadable results facilitate many types of visualization. There are plenty of examples online as well, including an analysis of everyday people's perspectives on the meaning of life, reasons for voter preference, analyses of U.S. political party platforms and inaugural addresses of U.S. Presidents.

Data can be analyzed in 65 different languages. This is a super great function if you are interested on doing research with people who speak varying languages other than English. But Raven's Eye analyzes English, as well.

Thanks Tapan ,shall check this PDF

Please suggest me a tool for analyzing the sensor data , and from where the sensor data repositories can be checked?

see this link its useful to u..

check this link  too..

hi, is there any link for sensor data (data repositories) and how can I make use of it for analytics, I mean is it possible using above tools?

It is relative on the database management system that you are using. for example ORACLE  12c integrates an important tools AWM for this also you can use OLAP or map-reduce with Hadoop. Also with MYSQL you can use phpmyolap ..etc     

Any text data, qualitative data, can be analyzed by Raven's Eye big data analytics. That is what I use for my big data projects. I have analyzed data sets with large population sizes, in many research projects. All you do is upload your data and Raven's Eye automated analysis gives fast analysis and graphics to explain findings even better.

You can use these analytics on any platform: computer, laptop, tablet or smartphone.

You can analyze text files and audio files with this cloud based data software.
