Visualization without data access, data management, data analysis
and interaction is nothing more than a pretty picture.
THE PROBLEM
Decisions have to be made based on data that are voluminous, complex
and coming at a very rapid rate. The raw numbers, in records or
tables, are overwhelming.
That's why many engineers and researchers are turning to Visual
Data Analysis (VDA) software, such as PV-WAVE® from Visual Numerics,
to better analyze their data. These tools combine state-of-the-art
graphics, data access, data management and analytical techniques
into a highly interactive environment that can interpret large amounts
of data quickly.
THE SOLUTION
VDA integrates several components of technical computing in a few
simple steps:
- The first is importing the data from acquisition
equipment as data files, in industry standard comma-separated
values, spreadsheet output options or custom file formats.
- The VDA software then manages the acquired
data in internal data structures or links to commercial database
management systems (DBMSs).
- Analysis tools -- including descriptive
statistics, signal processing and image analysis -- are often
included with VDA software.
- Two-dimensional and three-dimensional graphing,
image display, real-time interaction tools, animation, window
management and other visualization tools are built into the VDA
software.
- High levels of interaction are critical
when technical analysts are sifting through data haystacks for
discovery needles. VDA transforms the data into discovery.
Process vs. Pictures
 Most
analysts in the scientific and technical disciplines collect and
store data in their own homegrown formats, propagating the lack
of data management standards. In commercial markets, transaction
or event-based data are often stored in commercial DBMSs with a
common data access and filtering path such as structured query language
(SQL).
 Once
data are acquired or simulated, they must be imported into analysis
and visualization software. Data import is often the most time-consuming
process because the analysts or the technical support team must
build interfaces for siphoning raw data into the analysis and visualization
package. Lacking easy-to-use data-import tools, the analyst has
had to act as a locksmith, developing special "keys" for
each data format that allow the data to be read into the VDA system.
RETURN ON INVESTMENT
Most data-analysis packages provide tools for this data cleansing
that eliminate or interpolate over erroneous values. Once cleansed,
data have been read into the data-exploration software, and analysts
can navigate through several exploration operations to look for
information.
Simulated data usually come from compute-intensive applications
such as materials testing or CFD. Acquired data may come from a
sampling device, a satellite or other sources from which data come
either at regular time intervals or as event-driven records.
When a meaningful discovery has been made, staff can store the
subset data, the visuals or both and prepare a hard copy of results.
The key success factors for these and other data-intensive applications
are integration and interaction.
Visualization without data access, data management, data analysis
and interaction is nothing more than a pretty picture.
