BIReady is intended for generating and maintaining a Business Intelligence and Reporting solution based on a Data Warehouse and Data Marts. It reads the structure of the source systems and together with user input about history settings it generates the data warehouse. Because of the sophisticated concepts and algorithms within BIReady it is not necessary to do extensive changes to your ETL processes when the structure is altered. If significant alterations are required, they are done fully automatically by BIReady with conservation of existing data.
