System map

This page shows how the wiki domains connect. For the page/domain matrix and intentional exceptions, see the Wiki structure map.

Connection	Meaning
Master Data -> all domains	Enterprise/BU/Site/Account/Attendee/Program provide source data, scope, settings, and sessions.
Booking/Subscription -> Finance	Submit/confirm or billing schedules produce billing, invoices, credit notes, and projections.
Finance -> Payment	Finance owns documents/payment options; Payment collects through PayLater/PayNow/DD/Deposit/providers.
Payment -> Finance	Provider results and payment batch state feed reconciliation and invoice/projection status.
Business domains -> Platform	Domain state changes can publish events, write history, or create notification jobs.
Platform -> Communication	Notification jobs are rendered and delivered through the messaging pipeline.
Communication -> Users	Email, push, SMS, and in-app messages reach recipients.
Shared foundation -> all	Topi/Tuke/Tux, storage, timezone, and conventions support every domain.

One event across the system (example)

“An admin approves an invoice in Subscription” → what happens?

Current flows to locate quickly

Flow	Main path
Subscription Extend/Rollover	Customer/Admin → Subscription service → period/enrollment runtime → Finance reads the new schedule.
Closure Day reconciliation	Finance → issued-minus-active-credit → adjustment/projection → Xero event after commit.
Settings context change	Topi/Tuke → unified settings snapshot → hierarchy cache invalidation → client selectors.
Statistics	Dashboard/Booking Manager → IStatisticsService → shared provider/cache.
Notification trace	EntityEvent/action → NotificationJob → OutgoingMessage with SourceKey → delivery status.

Real-world example: If Dashboard and Booking Manager differ for the same period, check that both use IStatisticsService with the same context and that the cache was refreshed/invalidated.
