Integration Catalogue

Every way the platform touches another system, with protocol, cadence and direction — including the two it is allowed to write to.

Mobile shares the web contract; the existing lake is mounted as a OneLake shortcut rather than copied. Only procurement and the workflow engine are written to, and only after an approval. v 1.0 · owner Data & AI Global Practice · date 2026-09

Decisions

  • Read integrations are pulled on a declared cadence rather than pushed. A source that pushes is welcome to, but the platform never depends on it, because a missing push is invisible and a missing pull is an alert
  • The existing lake is mounted as a OneLake shortcut rather than copied. Copying a customer's warehouse into the platform doubles the storage bill and creates a second version of the truth
  • Writes exist on exactly two interfaces. Every other arrow out is a notification

Numbers

  • Fourteen interfaces at go-live; the prototype takes three (ERP/finance, procurement, projects)
  • Cadences: seconds (events), 15 minutes (finance CDC), hourly (projects), 4-hourly (documents), nightly (HR, CRM, market)
  • Each interface carries a freshness contract, and the answer states which one it used

Risks

  • Legacy public-sector ERPs frequently have no CDC capability. The fallback is a nightly full extract, which changes what "what changed since yesterday?" can honestly mean — and the answer must say so
  • The workflow engine write is the highest-blast-radius interface in the platform. It is the one with a dedicated connector identity and a re-check at execution time (view 20)
