This is my idea of a generic infrastructure for Realtime Risk (RR).Ideas are not entirely mine and have been gathered through severalassignments I have held in Capital markets.If I had my way with sufficient funding this is how I would implementA financial risk management environment for an enterprise.I have tried to build a case around basic and essential requirementsto achieve seamless integration within the orgamization and with externalparties.customers have a different view of risk. I also believe it ishard to capture what exactly customers mean. Best practice in my opinionis to allow them to interact, discover and set their own risk parameters.Given all the data that is available from Yahoo and other internet outlets andgiven technologies like R and XML, Unix it is possible to engineer an easy toinstall, customize and create value. Free Software (GNU Style).
