  Big data is no more "all just hype" but widely applied in nearly all aspects
of our business, governments, and organizations with the technology stack of
AI. Its influences are far beyond a simple technique innovation but involves
all rears in the world. This chapter will first have historical review of big
data; followed by discussion of characteristics of big data, i.e. from the 3V's
to up 10V's of big data. The chapter then introduces technology stacks for an
or-ganization to build a big data application, from
infrastruc-ture/platform/ecosystem to constructional units and components.
Finally, we provide some big data online resources for reference.
