- BM-Core is BlueMind's core component. It serves a a single management center for data and business rules. It is the only component that accesses the database.
All functionalities are exposed as Web Services and can therefore be driven by other applications.
All components, whether internal or external, use Web Services. This is useful for limiting incoming and outgoing BlueMind Mail flows (which are restricted to Web Services flows and mail flows) and ensuring the use of consistent management rules whatever the point of entry of a modification.
