I have a particular business case and wanted to know if Pentaho Reporting would help me in achieving this functionality. It's a J2EE based project and pertaining to Financial data that we get from Bloomberg Terminal in XML format, which we apply some mathematical models and forecast the stock price of the company 3y, 5y, 7y down the line generating dynamic spreadsheets which include pie charts, bar graphs on which we further run (time series) regression models and generate the speculated risk and returns of the firm as juxtaposed with the benchmarks used.
Let me know if Pentaho has some each solutions to this.
Business Intelligence tools definitely address this type of scenario. Kettle, Pentaho's ETL tool, can be used to extract the data from bloomberg and populate an internal data mart, Weka, Pentaho's Data Mining tool can be configured to run standard models for forecasts, and Pentaho Reporting can be used to generate your excel documents including charts.
