I'm a CS major, but my University only has the typical CS courses. There is a Data Mining course, but I found the course to be more theory than hands-on stuff. Also how much math training is required?
Have an Answer?
Data scientist with a solid foundation typically in computer science and application, statistics,analytics and math. From Math perspective, as far as you've have fundamental mathematics knowledge you should be good. You don't have to master linear algebra or discrete mathematics. Data scientists are strong business acumen coupled with the ability to communicate to business and to the IT department to approach a business case/solution. In academic courses, they offer clustering, load forecasting, Rules, datasets, analytics such as decision tree, ad optimization etc to understand the fundamentals so that you will be able to adapt to the real world scenarios. From IT corporate perspective , there are plenty of tools available depending upon the type of company and industry. Typically data with SQL interfaces or analytics tools will give visual representation not only spot trends but also to question the assumptions and the business process to give recommendations and conclusions. It is a very interesting and handy course in today's competitive world.

Please visit www.bigdatauniversity.com they have various free intro courses in Hadoop and data mining. Also visit www.tdwi.org/. Big data is useless unless it can answer relevant questions.
Data is stored is databases. Computer Science teaches you how to manage and access databases. Master CS and you can master data. Some math is required, databases don't typically require calculus ;-)
