I am concerned whether Rails can handle the types of complex aggregations that are needed for a financial application and particularly whether the ORM can handle these effectively. In a financial application that I am thinking of using this for, there is a need to do lots of reporting of detailed financial data, aggregated in various ways. Without support in the Rails ORM, I would need to write direct SQL. But I am concerned that once I start this, other parts of Rails may not work as well and that as a result I may end up mostly using Rails for its routes and very little else. Is this a valid concern or am I worrying needlessly?
