Overview

Impact Analytics provides its customers with sophisticated predictive analysis and trending from a current, massive database of over 20000 media feeds and online data sources. Impact Analytics has the ability to accurately predict emergence and shifts in public perception and reaction intensity on customer selected issues such as stock price changes, technology trends, election outcomes, political movements, economic changes, product popularity and many others. Analyses that normally require weeks and hundreds of man-hours, can be constructed in only a few minutes, with depth and timeliness, and the help of business intelligence products from Impact analytics.

Challenge

Impact Analytics have developed a business intelligence tool IDXReduction, which was used in analyzing the media feeds and online data sources. This tool was developed in Visual basic. The real-time data that is being analyzed is massive and involves huge number of file/disk operations. As a result the tool was consuming large amount of the system resources and the performance was not satisfactory. More over this tool is affecting the performance of other applications running on the system as the system resources are shared among them.

Solution

PositiveEdge team has analyzed the tool that was developed in VB by Impact analytics and has proposed and ported this tool to Visual C++. C/C++ language provides efficient methods for file operations and optimized string manipulations using pointers. As the tool has to deal a lot with file operations and string manipulations, developing this tool in VC++ yielded best optimal performance. Results from the new version of the tool indicate that it is 3 times faster than the original version and around 50% better in resource utilization. This proved invaluable in giving the customers accurate shipping cost information.
