System of record
A piece of information, for example, a customer address, is maintained by only one system, which is the system of record (SOR). The SOR publishes all changes for that piece of information to Infor ION through a Sync message. Other applications that want to add or update that piece of information must make a request to the System of Record by using a Process message.
The system of record does not need to know which applications require the information. The entire contents of the document are published in the Sync message. All applications that subscribe to the message receive a copy of the message from ION.
