Overview

SSP "external" tables/views do not enforce referential integrity, but loose, logical dependencies do exist between them. In some cases, even when such a logical dependency exists, it may not necessarily be the case that the depended-on record actually exist in order for the system to function. So producing a completely accurate dependency graph would be a complex effort and likely frequently subject to change as the application evolves. But some deployers have requested guidance on a recommended order in which to update these tables to ensure the complete dataset is an internally consistent as possible at any given time. This document provides such a recommendation. Keep in mind of course that this is just that - a recommendation. Not all the tables listed are required and other orderings might be perfectly valid.

...

This document also provides a "primary use" column which tries to indicate the SSP subsystem that makes heaviest use of the data in any given table. This is intended to help provide implementation prioritization guidance when trying to decide which tables to "support first", inter-table dependency considerations aside. E.g., while external_faculty_course may be listed ahead of external_course, these tables have no logical dependency relationship. So if your deployment is more interested in the MAP subsystem than in the Early Alert subsystem, you needn't populate external_faculty_course before populating external_course.

external_department, external_division (You might think this table should precede external_student_transcript_course in a sort of master-detail relationship. But external_student_transcript_course uses a less strict definition of course and the application does not use external_course to provide additional context when rendering external_student_transcript_course records. There is a relationship between these two tables, but if anything it flows the other direction, i.e. at the app layer external_course records are checked against external_student_transcript_course to determine if a planned course has already been taken.)

external_person (Note that while this table refers to the same notion of a "course" as external_faculty_course and should use the same course and section identifiers, there isn't really even a logical dependency between the two tables because external_faculty_course should only contain "early alertable" courses whereas a student transcript should list all transcripted courses for any given student.)
