Denodo ITPilot allows creating programs (also called “wrappers”) that
perform automation and data extraction tasks on websites. These tasks
normally imply automating complex navigation sequences through Web sites
that may involve authentication processes, form filling, frame
NSEQL navigation sequences do not have to be manually written: Denodo
ITPilot allows to record new navigation sequences of any complexity by
entirely graphical means.
Navigation sequences are recorded using the “Navigation Sequences
Generator”, that takes the form of a toolbar that is installed in an
MSIE browser. Once installed, it can be used to generate any navigation
sequence on the user’s browser using a process very similar to normal
browsing, the recorded sequences are automatically translated into an
NSEQL program that replicates the navigation sequence.
It is important to note that the necessary events for running
a navigation sequence in a browser type do not always match those
necessary in another type. This means that the NSEQL programs produced
by the Navigation Sequence Generator may have to be adapted before being
run with a browser pool configured to use Denodo browsers.
This generator may also generate browse sequences using pattern http
requests; their characteristics and differences with NSEQL are explained
in section Advanced Options.
