"The system that definitively specifies data values. In dealing with redundant data, you can have values that should be the same but disagree. The system of record is the system you go back to, in order to verify the true value of the data." (Microsoft Corporation, "Microsoft SQL Server 7.0 Data Warehouse Training Kit", 2000)
"The definitive and singular source of operational data. If data element ABC has a value of 25 in a database record but a value of 45 in the system of record, by definition, the first value is incorrect and must be reconciled. The system of record is useful for managing redundancy of data." (William H Inmon, "Building the Data Warehouse", 2005)
"The single authoritative, enterprise-designated source of operational data. It is the most current, accurate source of its data." (David Lyle & John G Schmidt, "Lean Integration", 2010)
"A system that stores the 'official' version of a data attribute." (DAMA International, "The DAMA Dictionary of Data Management", 2011)
"The system of record is a system that is charged with keeping the most complete or trustworthy representation of a set of entities. Within the practice of master data management, such representations are referred to as golden records and the system of record can also be called the system of truth." (Laura Sebastian-Coleman, "Measuring Data Quality for Ongoing Improvement ", 2012)
"Records from which information is retrieved by the name, identifying number, symbol, or other identifying particular assigned to the individual. Sometimes abbreviated as SOR." ( Manish Agrawal, "Information Security and IT Risk Management", 2014)
"An information storage system (commonly implemented on a computer system) that is the authoritative data source for a given data element or piece of information. The need to identify systems of record can become acute in organizations where management information systems have been built by taking output data from multiple-source systems, reprocessing this data, and then re-presenting the result for a new business use." (Janice M Roehl-Anderson, "IT Best Practices for Financial Managers", 2010)
