Technology
QlikView's core technological differentiator is that it uses an
in-memory
data
model
,
which stores all of its data in RAM instead of using disk. As RAM is much faster
than disk, this allows for very fast response times, resulting in a very smooth
user-experience.
In a later part of this chapter, we will go a bit deeper into the technology
behind QlikView.
Adoption path
There is also a difference between QlikView and traditional BI solutions in the way
it is typically rolled out within a company. Where traditional BI suites are often
implemented top-down—by IT selecting a BI tool for the entire company—QlikView
often takes a bottom-up adoption path. Business users in a single department adopt
it, and its use spreads out from there.
