Focusing on SQL queries.  discussion topic is data report.

focusing on SQL queries.  discussion topic is data report. I would like to ask everyone to share an example of data report you are familiar with. Ideally this is a report generated from an underlying database for health related applications. The discussioncan include the following items:

1. The specific data items in the report;
2. The underlying tables and data fields in the database that are used to generate the data report. Is the data source of the report from a single table or multiple tables?
3. How the data are entered into the system? In addition to generate the data report under discussion, are these data used for other purposes?
4. Potential issues you have found about the report (data completeness, consistency, timely update, etc.).
