Business Open Source Blog. Business Open Source Blog. Rückblick auf ein ereignisreiches Jahr. Letzten Monat ist es genau ein Jahr her, dass ich zu it-novum wechselte, um das openATTIC-Projekt. Zu leiten. Wie die Zeit verfliegt, wenn man an spannenden Aufgaben arbeitet! Ich hatte die Stelle mit dem Ziel angetreten, die Entwicklung der Storage-Plattform offener zu gestalten und die Community auszuweiten und stärker einzubinden. Interview: 30 Jahre IT in Österreich. Die meisten Administratoren im IT-Sektor ...

S approach is not longer to use hard disks for storage of data, but instead to use RAM. By shifting the data in RAM, the access time can be reduced by factor of 1000, thus making the Read-/Write- operations significantly faster. Fast access to data in memory, enabling significant performance improvements in analysis and planning compared to data stored on hard drives. Memory size significantly less and more expensive than with traditional hard drives. Data is lost in case of power failure or reboot.

About this Benchmark - olap-benchmark.de
http://www.olap-benchmark.de/en/benchmark/index.html
The benchmark presented on this website was created as part of a master thesis written at University of Applied Science, Karlsruhe. The starting point was the fact that the performance plays very important role in almost all BI projects, but there is no objective benchmark which potential customers and users could use to determine which product is the fastest. All this is happening although Analytical Processing Benchmark (APB-1). However, it was possible to draw important conclusions.

Performance matters - olap-benchmark.de

Performance is certainly only one of many criteria in selection and operation of a BI system, but it is also one of the most important. Yearly BI Survey. Showed in recent years performance as no. 1 problem in BI projects and systems. It was only in 2010 that data quality pushed performance into second place. So performance is not everything, but without good performance everything else doesn’t matter. Without doubt, in worst case scenario performance can bring BI project to halt.

To obtain comparable performance results for different products, the basic conditions must be as identical as possible. In order to draw practical conclusions, the data models. Should be based on real-world scenario. All OLAP products were installed on the same hardware. And the data used in models was based on analysis of customer applications in the field. 2010 - 2011 Imprint and Contact.
