Commonly, there are large quantities of data that are collected on a periodic basis to assist with monitoring and evaluation and/or reporting to external funding agencies. Often, the reports in question are a combination of aggregate patient data (to be retrieved directly out of patient records) and aggregations of other data that is not directly captured at the patient level in the system. Allowing a mechanism for recording this "other data" in the system facilitates our ability to create reports that easily combine all data into one report, regardless of it's source.
