Overview
Previous versions of this doc called its top-level organizational categories "Phases". That was a bad name outside of the "Core Planning" category, b/c while that matched up with the first software delivery interval, everything else was more of an abstract set of feature groupings that happened to be listed in perceived priority order, but could technically be reordered with minimal design impact. So I've switched out "Phase" for "Feature Set".

| Column | Type | Notes |
|---|---|---|
| id | uuid | Self-explanatory |
| plan_id | uuid | Pointer to the plan which owns this course-term binding. Formal FK to map_plan.id |
| person_id | uuid | Pointer to the person to whom the plan applies (as opposed to the author). Formal FK to person.id. Must always match map_plan.person_id for a given plan_id. This is a denormalization for performance. |
| term_code | varchar | Pointer to the term in which the course is planned. Informal FK to external_term.code. Integrators are strongly encouraged to use term_codes with business meaning, e.g. FA12 not 1234. This seems common enough that taking a copy of the term name/title is not necessary. |
| course_code | varchar | Pointer to the course being planned. Informal FK to external_course.code. Recall that this is a potentially opaque value, not something like "MAT101". |
| formatted_course | varchar | Copy of external_course.formatted_course. Should be something like "MAT101". Needed to produce a useful plan export should external data go missing. |
| course_title | varchar | Copy of external_course.title. Needed to produce a useful plan export should external data go missing. |
| course_description | varchar | Copy of external_course.description. Needed to produce a useful plan export should external data go missing. |
| credit_hours | varchar | Copy of external_course.min_credit_hours (per email from Jason). |
| is_dev | bool | Copy of external_course.is_dev. Needed to produce useful plan export should external data go missing. |
| order_in_term | int | Ordinal representing desired on-screen position relative to other map_plan_course records in the same plan and term. Ascending order. |
| {audit-fields} | -- | Standard stuff |
Feature Set 1 Operational Data Model Notes
No roll-up hours total on map_plan b/c that's presumably an optimization we don't know that we need. But we will support output of totals on-screen, in APIs, and in reports. Just not going to require the persistent sum until we know we need it.

Feature Set 2 Operational Data Model Notes
UI is expected to pre-populate contact_* form fields with the currently authenticated user's attributes. We intentionally take copies of those values into map_plan at Russ's direction. Advisors are sometimes reluctant to expose certain attributes to students. We choose to accept the potential for out of sync attributes as a result.
...
Restricted access to the various contact_notes fields must be handled server-side. I.e. the API can't just always return contact_notes whenever looking up a plan and hope the UI enforces permissions correctly. Same for writes, but in the other direction.

Feature Set 3 External Data Model Notes
We don't need a list of programs without courses to support search features, but we require external_program anyway b/c we know we need that feature for plan templates (Feature Set 4). The denormalization of program names into external_course_program is an optimization to help search, though, which really only does need the list of programs having at least one required course. This lets that lookup avoid one join. And denormalization in external data is OK as a general rule.

Values for requisite_code were discussed on the dev list.
TBD
| Code | Definition |
|---|---|
| PRE | requiring_course_code requires that required_course_code be taken in a previous term |
| PRE_CO | requiring_course_code requires that required_course_code be taken in a previous term or concurrently |
| CO | requiring_course_code requires that required_course_code be taken in concurrently |
Trying to use only two requisite_code values to model a bi-directional "Co" restriction will not work. E.g. BIO+BIO_LAB must be taken as a pair. If you model BIO->BIO_LAB (Pre-Co) and BIO_LAB->BIO (Pre-Co), then you'll catch cases where they're taken independently and *only* independently. But if you have a plan where they're taken as a pair in one term, but then BIO is added again in a later term, the mistake won't be caught.

The basic requirement is to indicate to the end user whenever viewing a plan or adding/editing a course to/in a plan when that course already appears in the user's transcript. Per Jason, "The business requirement is to check the planned courses to see if the student took them....Speed and accuracy are the keys." Because of that (esp the "accuracy" part), we're not going to copy a "transcripted" flag/status onto the operational model. Determining whether or not a planned course is already transcripted will always be a transient join/lookup.
...
Our transcript table/s do not know about course code. We accept the potential ambiguity despite the stated priority of "accuracy". That value is likely just not available in transcript feeds.
