Data sources: The times and dates are internally generated by MySQL based on the data types used in the table. The remaining fields, with the exception of the Incident_num which is internally generated, are determined by the HTML form inputs. Some form inputs are not inserted into the database but just used to guide processing [like the reporters indication as to whether they want an email copy of a submitted report, or not]. Some inputs like the email address, and the reporter (name) and password are already in database tables, and are only accessed [retrieved] for purposes of controlling authentication or email authorization. Some database columns, like the email limit for a reporter and their current number of sent emails, are entered manually using phpMyAdmin. They may be accessed for decision-making [like the email limit for an address] and update by the program when an email is sent.
