- Portable Database Image
The Portable Database Image, also know as [http://www.panoratio.com/204.0.html .pdi] file, is a
proprietary loss-less format designed foranalytics ,publishing and syndication of complexdata . The .pdi footprint is typically 100 to 1000 times smaller than the footprint normally found in structured data files ordatabase systems , and isrendered without any loss of detail. A .pdi runs in themain memory of a user's’computer without disk or networkinput/output (IO). There for the name of the file format is portable as in transportable.The .pdi is a digitally rights protected,
encrypted data source that can be accessed by any [http://msdn.microsoft.com/library/default.asp?url=/library/en-us/oledb/htm/oledbforolapoverview.asp ODBO (OLE DB for OLAP)] compliantOLAP tool, [http://www.microsoft.com Microsoft] [http://www.microsoft.com/office/excel Excel] and the [http://www.panoratio.com Panoratio] [http://www.panoratio.com/91.0.html Explorer GUI] .The .pdi presents detailed discrete or binned data without pre-calculation or
cardinality reduction. It allows for real-timecorrelation and relationship exploration of unrestricted bounds — throughout all dimensions. They (.pdi’s) have been tested in excess of 5,000 dimensions and 500 million rows of information, with query response times in the .1 to 8 second range.Additionally, because of patented techniques used in .pdi generation, patterns found in the data are summarily exposed, allowing for instant predictive and descriptive data mining. Yield optimizations, segmentation, outcome optimizations and simulations are all dynamically supported by the .pdi format. Users are constantly presented with the most changed and most highly correlated dimensions affected in every query as discovered in the patterns of the historical data.
The .pdi format, generation process, and GUI, were invented by Dr. Reimar Hoffman and Dr. Michael Haft from
Siemens AG Artificial Intelligence /Machine Learning .External links
