QA reports on mortgaging

In order to reduce risks associated with financing real estate by using suitable control instruments, it is necessary to identify those risks. These risks include, for example, delays in paying interest and repayments, or a complete failure to repay on the part of the borrower. Data on the history of real-estate credits and other information about real estate (e.g. the borrower's credit rating, sales of parts of the real estate) collected over a long period of time are evaluated and these evaluations are grouped together into reports that help identify risks. The data that is needed for the evaluations is stored in a data warehouse and it comes from numerous upstream systems.
