Can Datamartist replace all data warehouses and data marts?
Absolutely not. Very large (and expensive) server based systems will always be required to one degree or another in most enterprises. What Datamartist does is provides a way to avoid creating unneeded server based, or custom developed database systems for a wide range of data transformation needs. Every time a data mart or data warehouse project is avoided, huge cost savings result. Datamartist provides a tool that allows data transformation (and then the follow up analysis in an analysis tool) that would never have happened, because the data transformation was too complex for Excel, but IT resources did not exist to implement it in a database.
