It sounds like a data processing pipeline rather than a database itself. A systems A...E at hospital push csv files to a shared system F. System G pulls the data from F, passes it through an excel workbook (failure point!) for data augmentation and cleanup tasks built by a public health SME, the drops the data in location H. System I loads the data then finally loads the data to a “real” database for additional reporting. If that sounds insane, I assure you that is a simplified version of what happens in some systems.
