Single source of truth
Architecting for a single source of truth means designing a system where each component pulls from a single authoritative location for data and all updates flow back to that central system. This practice is typically referred to as MDM. Although it is helpful to be familiar with this concept when designing a B2C solution architecture, this approach alone cannot create an integrated B2C solution on Salesforce.
The primary reason why we need to integrate products together rather than leverage a single source of truth is that each component product in the Salesforce B2C solution architecture ecosystem is designed to rely only on its own internal representation of data. Because these are SaaS solutions, there’s no way to change the underlying data model. By building custom components using tools like Lightning Platform LWCs or B2C Commerce SFRA changes, the user experience can be de-coupled from the platform data model, but this introduces significant complexity...
