A system of record is an authoritative system for specific data elements within an organization. For example, an HR system serves as the source of record for employee data, while your CRM system may be the equivalent for customer data.
Whatever its use case, an SOR ensures data accuracy, consistency, and integrity by serving as the primary repository for critical information. It helps support compliance, decision-making, and interoperability across systems.
Systems of record is a broad term, as it covers a range of functions. If you’re unsure whether your solution fits the definition of an SOR, consider the following:
- Does your solution store proprietary business data?
- Is your solution used by employees on a daily or weekly basis?
- Is your solution essential to business processes?
- Do you require your solution to make key business decisions?
There are several components of a system of record. These components include the golden record, master data management (MDM), and the source of truth.
The golden record.
Underpinning any business or organization’s data is the golden record. It consolidates all the data an organization holds on each data entity — employees, customers, and products — to provide a single source of truth. Created by the master data management (MDM) platform, this resource combines data stored across various systems, including SORs, into a single dataset. The golden record is understood to be an organization’s most accurate, consistent dataset for each entity.
Master Data Management (MDM).
The master data management (MDM) platform is what creates the golden record discussed above. To achieve this, the MDM consolidates data from multiple sources and cleanses it of duplicates and conflicts. This means it can establish a single source of truth across an organization’s key data entities.
Source of truth.
A source of truth refers to the authoritative source for a particular data element within an organization. While systems of record focus on storing and managing business-critical data — such as customer records or financial transactions — sources of truth are more concerned with data architecture and governance.
Sources of truth emphasize the technical infrastructure that ensures data consistency across systems. This includes how data flows through APIs, data lakes, and integration layers, as well as how it's synchronized between platforms.
A source of truth also involves data governance — the policies and practices that define how data is managed, accessed, and controlled across the organization. In short, while a system of record is concerned with where data resides, a source of truth is concerned with which version of the data should be trusted and how that trust is maintained.
