The Item_Categories field contains a set of values that represent entries in the Item Category table. Because the sets do not contain record IDs, this creates an indirect one to many relationship from these records to the records in that table.
Each Allergens_Present and Allergens_Absent field contains a set of values that represent entries in the Allergen Category table table. Because the sets do not contain record IDs, this creates an indirect one to many relationship from these records to the records in that tables.
Records in the Allergens and Availability tables have pointers to records in this table. Each record in the Establishment table can be pointed to by one or more records in those two tables. That is a one to many relationship from these records to those records.
The Modified_By and Created_By fields in these records each point to single records in the Food Detective table. Because a food detective can create multiple entries in the database, this can produce a many to one relationship between these records and the Food Detective records.
