Abstract: Sales-Performance Analysis strategy integrates the concepts of Data Mining, Analytical Processing and Data Warehouse to support organization`s decision-making process. In this study we have presented analytical-requirements and design-issues of sales-performance analysis for data warehouse design. For these requirements and issues, modern decision-design based experimental model has been anticipated and evaluated. For evaluation, two parameters (success, suitability ratio) has been defined and used. The present study shows, 1) The experimental model provides better scalability, for analysis, mining and reporting, than the formal decision designs 2) Experimental model can be used for various Sales-Performance Analyses like product profitability, channel analysis, product sales analysis etc.
