theories  models  and application scenarios. Divided into three main parts  it addresses what
data science is  how and where it is used  and how it can be implemented using modern open
source software. The book offers an essential guide to modern data science for all students 
practitioners  developers and managers seeking a deeper understanding of how various aspects of
data science work  and of how they can be employed to gain a competitive advantage.
