Data about sales of OTC health care products are processed separately by the National Retail Data Monitor, which is discussed in detail in another article in this issue of JAMIA. 23 The processing was kept separate intentionally because, in the future, the servers for the National Retail Data Monitor may operate in different physical locations than RODS. The RODS user interfaces can and do display sales of OTC health care products as will be discussed, but other user interfaces can be connected to the National Retail Data Monitor as well.
