For us we have giant database like applications that consume data across the entire bank to calculate risk indicators. There are all kinds of risk at a bank so it gets pretty complicated with all the products we have. They either generate views for downstream business partners or directly generate reports. The views are frequently over 1000 columns wide and are at an account level (the data is initially transaction level). We also have some web apps to provide a user interface or off the shelf customizable reporting like tableau or microstrategy.
