The integration direction between the systems is one-way integration from the SIS to Salesforce for

the IT department that is determining its integration needs between a Salesforce implementation, its

SIS, and its housing system. One-way integration is a type of integration that allows data to flow in

one direction from a source system to a destination system. The SIS is the source system and

Salesforce is the destination system for the contact information and the housing mailing information

of the students. The IT department should set up a one-way integration from the SIS to Salesforce to

ensure that the data is consistent and accurate in both systems. One-way integration with Salesforce

to the housing system, one-way integration with the housing system to Salesforce, or one-way

integration with Salesforce to the SIS are not correct integration directions between the systems.
