Data science has evolved in the recent years into new industry. Definitely we will see more demand for data skills in every job. I will suggest you to start with www.coursera.com where you can register and audit the data science courses for free. These course will give you idea of theories and application of data science. But, I will warn you that the theory is more mathematics intensive. In practice you may end up with some programming libraries to work with.
Even before you start , here is a basic division of the data industry..
Data acquisition, Data management and Data processing ( or Data interpretation)
Data acquisition is from sensors, or websites, or human surveys. This is where most of the work force is required.
Data management is about how to save in servers, access large data and often different types of data. This requires in depth knowledge of servers and administration, and some new file systems like hadoop(many more).
Data processing this is where many people use the statistical and machine learning tools to take meaningful actions from the data. This is often referred as data science or persons who program this is referred as Data scientist.
I know this a lot to go over, but if you are interested in this field this basic explanation gives idea on what to search for in the internet.
