Reception, service and charging may all use the same file, but the information required for each position is different. Dividing purposes when creating a file can reduce repeated entries and unnecessary information display. The number of fields is not the only criterion for file integrity.

File scope

Separate contact information, service records and health information collected with authorization. Fields should not be copied just because they are used by other organizations. First ask who provides the information, in which service link it is used, and whether the absence of this field will affect work.

Role access

Reception staff need appointments and contacts, and nursing positions need records related to current services. One complete profile page cannot satisfy all roles, but the list, details, modification and export scope should be planned separately.

Change traces

Addresses, contacts and service status may change. Important fields must be able to view the modification time and responsible person. Historical records should be kept interpretable to avoid overwriting old work orders with new data and causing them to lose their current business context.

Scene verification

For example, the same file can display only appointment contacts on the reception page and current task information on the service page. First draw the information scope of the two types of pages to help find unnecessary fields and permission overlaps.

Specific verification method

Use the reception account to query the file and check whether only the information required for the appointment is displayed; after changing the contact person, check the old work order to confirm that the current information can still be found; then export it as a service position and check whether the field exceeds its access scope. There should be clear feedback for unauthorized requests.

The file fields should correspond to the actual usage. Data that does not have a job position or reason for preservation can be postponed for collection; important changes should be recorded with the effective time for subsequent review.
