From this information we can indirect interpret growth of these tools in monetary terms and their number of users growth. More revenue means more users and more project they are handling.
SAS has achieved a business turnover of about 3.09 billion dollar as per 2014 report. R is free software, so we cannot get any business turnover for it. Excel is a part of Microsoft office package, so it very difficult to calculate business turnover only for excel. Python is again a freeware. Tableau – TABLEAU revenue as per 2013 is 232.44 million dollar
But if we have to rate these tools in contribution of total revenue, then on the scale of 1 to 5, where 1 id for least and 5 for highest:

- Handling Big Data capability
In terms of big data handling capability, SAS can handle any amount of data and process it for any statistical test. R can also work with big data but you need to keep higher RAM size. Excel can keep only around 1 million rows in one worksheet.
Tableau Desktop and Tableau Server can handle any limit of data depending upon RAM size, disk space, and type of database used. It does not have any enforced row or column limits for the amount of data. But by increasing volume of data their performance gets affected.
Python can also be used extensively in the field of big data. There are couple of packages that can be useful while working with big data using python. These packages are
- NumPy – The Fundamental package for scientific computing in Python
- SciPy – Mathematics, Scientific and Engineering package
