I am in the process of modeling some automated data transfer and transformation processes and was curious if anyone had some suggestions on what's the best model type to use for this. The overall process we are modeling is basically data residing in a source system being sent to a receiving system. There may be several places between the source system and the receiving system where the data may reside for a period of time without being modified or where the data may reside for a period of time and be modified. The information we are interested in capturing for these processes are the hardware specs (i.e. servers, routers, firewalls, etc...) that the data passes through or resides momentarily and the application specs of the systems that actually transforms the data between the sending and receiving systems. Thanks in advance for any advice you can offer with this!
