DESL (DEE-zel), the Data Engineering Scripting Language,
provides a flexible command interface to its powerful underlying
engine
that can be used by the user to manipulate and visualize
spreadsheet-style numerical data
in a variety of ways. DESL is the successor to the package
known as HyperDAS.
The roots of DESL are in the aeronautical industry,
particularly having been associated with NASA wind tunnel data reduction
and data manipulation and display. In such an environment data is
collected and stored in a "point by point" sequence. Such data, thus
collected, can easily be dealt with with the DESL software system.
Other engineering and experimental endeavors which must deal with
data of a similar form, can benefit equally well
from the simple, effective building-block approach to dealing with
data which DESL allows.
Through a set of user specified stages of data manipulation - i.e.
data engineering - DESL can provide the means
whereby user goals can be easily achieved.
Although the roots of DESL are in the aeronautical industry
other engineering and experimental endeavors can benefit equally well
from the simple, effective building-block
approach to dealing with data.
For each command
issued, the user-specified options and
option arguments can direct DESL to do
exactly
what is desired.
The
name-oriented nature
of the binary
Standard Interface File (SIF),
which DESL uses to
internally
store and process data,
is the key to the convenient and flexible manner in which
particular variables are
identified, coordinated and used
.
DESL can be used to accomplish such
commonly-occurring goals
Before you go any further, please take the time to get a
flavor of DESL.
And, please review the latest updates that
have been made to DESL. Some feature(s) you have been waiting
for may have been added.
DESL's scripting nature
Scripting tools (languages) allow the user to provide
high level
specifications (commands and arguments) to an underlying package in
order to accomplish goals.
The
command line,
scripting nature of the DESL interface allows all of
its file-oriented
power and functionality to be directly brought to bear by the user.
