Source system
The source system supplies data for a particular transfer path. That role alone does not establish who authoritatively maintains all business information.
A source system is the system from which data originates for a particular transfer path. The term describes a role in the data flow. It does not automatically mean that this system authoritatively manages all information about the business object concerned.
Name the source for each data flow
In a fictional product data exchange, the PIM supplies descriptions to the shop. For stock messages to the same shop, the ERP is the source instead. A blanket statement that “the PIM is the source” would hide these different responsibilities.
Distinguish supply from data authority
Microsoft describes reading from a source and writing to a destination when copying. For your integration, also define which information may be adopted and which system should change it. Document the source, data scope and direction for each transfer path. A system supplying a value does not alone authorise overwriting other values at the destination.
