What is DESL ?

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.

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.

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.

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.

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 as :

  • general, conditional manipulation of the data
  • interpolation in the data
  • discovery of trends in data
  • preparation of data for subsequent analyses
  • graphic display and tabular reporting of data
