Engineers can use Labview data storage VIs to document their test data; TDM search-ready file formats to capture important test information; and now Diadem 10.0 to mine their test data
National Instruments says it is changing the way engineers manage and mine test data with the release of NI Diadem 10.0, the latest upgrade to the interactive software for inspecting, analysing and reporting test data.
The new version includes the revolutionary Diadem DataFinder, which gives engineers and scientists the power to perform internet-like searches across their data files, regardless of format.
Diadem DataFinder brings sophisticated data management and data mining functionality to the desktop at a fraction of the cost and without the maintenance challenges found in traditional IT-supported data management solutions.
Diadem has a long history of saving customers time.
"By using NI Diadem, we can turn our data into usable results in minutes rather than days," said Jim Knuff, principal systems engineer at Raytheon Missile Systems.
"We have documented an overall time reduction of 90 percent since we integrated NI Diadem into our system".
Engineers managing data face multiple challenges, whether they are working with too many data formats or relying on an inflexible data format.
The Diadem DataFinder uses the NI technical data management (TDM) data model as its internal data structure.
TDM files, written natively using NI Labview data storage VIs or NI LabWindows/CVI storage functions, provide three levels of hierarchy to structure test data - file, group and channel levels.
Having a rich set of attributes increases the range of possible search conditions.
Although optimised to work with TDM files, the Diadem DataFinder is capable of searching across all data files for which there is an associated DataPlugin.
The Diadem DataPlugin technology accommodates for legacy file formats, making them searchable.
Engineers can perform simple searches or even more advanced searches based on key descriptive information.
For example, engineers can use the Diadem DataFinder to search for all tests with a specific serial number, status and test type.
After narrowing the data set, engineers then can use Diadem to perform further analysis and reporting.
Diadem DataFinder also gives engineers and managers the ability to establish and uncover anomalies or trends that previously went unnoticed.
This feature is especially beneficial to technical professionals who are required to analyse and report measurement and simulation data, make recommendations based on results and share their findings with coworkers.
Diadem 10.0 enhances the suite of test data solutions offered by National Instruments.
Engineers can use Labview data storage VIs to document their test data; TDM search-ready file formats to capture important test information; and now Diadem 10.0 to mine their test data.
