[phpesp-general] Table relationships

[Neil P. <ne...@uw...>]

Hello,
   I have 16 tables in my phpESP 1.7.2 database. I was examining table 
'Access' and noticed records where values of 'realm' are not in the 'realm' 
table and corresponding 'survey_id' values are not in the 'id' field of 
table 'survey'. Is there a document that describes how all the tables are 
related? Is there a process which would identify orphaned records such as I 
expect exist in the Access table? Is there a cleanup process?
