Buzzwords like Data Mining, Data Analysis, Big Data were buzzwords that the whole world has gone crazy about. Now, another one joined or even displaced the previous ones - Data Science. If you would like to get to know what it is, learn how it can be used in practice, you must see this presentation. Rafal Lukawiecki in an interesting way introduces us to the Data Science subject in an accessible and comprehensible way. He does that using SQL Server Analysis Services, Azure Machine Learning and R. I totally recommend watching it.
Sound in the first 6 minutes is not the best but it is fine later.
