In the following example, three tables store information about the interactions between sales representatives and customers: Customers, Contacts, and SalesReps. Each sales representative sells to several customers. For some customers, there is a single contact, and for other customers there are multiple contacts.
For detailed descriptions of the tables, see Description of Contacts, Customers, and SalesReps tables.
A sales representative subscribes to a publication that provides a copy of the SalesRep table, a copy of the Customers table with the details of the customers assigned to them, and a copy of the Contacts table with the details of the contacts that correspond to their customers. For example, each sales representative subscribes to the following publication:
CREATE PUBLICATION SalesRepData ( TABLE SalesReps TABLE Customers SUBSCRIBE BY rep_key TABLE Contacts SUBSCRIBE BY (SELECT rep_key FROM Customers WHERE Contacts.cust_key = Customers.cust_key ) );
For a detailed description of this publication, see Using disjoint data partitions.
