About data processing with data types (System of Record, External System of Record, No System of Record)
Hey, so I'm trying to understand the difference between this three types of data storage.
I read the APPLICATION DATA PROCESSING WITH DATA TYPES from the System Archit Essentials and I do not understand these concepts, can anyone give me a simple explanation about Pega System of Record, External System of Record and No System of Record? And if it is possible to give me some littles examples when we use this type of data storage.
The System of Record (SoR) pattern is used when a case needs access to data that is stored in another
system or application. The case does not own the reference data. Data is referenced as needed by the
application for context or to populate rules. For example, a loan application or credit card dispute
accesses customer account information and history.
Data loaded from the SoR pattern usually comes from an external data source. The SoR pattern helps to
ensure that data displayed in the Pega application is current. For example, if the account holder has a
new phone number, the updated number is displayed when the data is accessed from the case.
