System complexity “Many integrations are required to make sure that an SOR has and easily promulgates the most up-to-date and accurate information.” For example, an MES might not only be configured to receive data from production lines, but also to connect with related supply chain management (SCM) systems to share information about required materials—and all of this might need to feed into a centralized single source of truth.
Data access “In the case of an enterprise application, such as a CRM or ERP tool, users can often access data directly through the app.” Users might also access data through a connected business application or tool, such as a data mart or data warehouse, which cleans and organizes data for business intelligence (BI) and other data analytics use cases.
A system of record (SOR) is an authoritative source of business data. SORs can contain authoritative data on customers, employees, products, suppliers or other assets and entities related to everyday business processes. Organizations use SORs to streamline core business functions and business decisions. “SORs help ensure that different systems within an organization can reference the most up-to-date, verified versions of important data elements.” SORs can also have cybersecurity applications. For example, organizations might use a secrets vault as a source of record for important credentials, or an identity and access management (IAM) system as a source of record for network users and their permissions.
