Data quality indicators and their use in data base systems

Robert L. Patrick

Expert InsightsPublished 1980

Describes a new concept in data annotation that enables a file to be maintained with descriptors which describe the quality of a file, the quality of a record, or describe the quality associated with a specific occurrence of a data element. Data quality indicators (DQIs) are descriptors used in computer file systems to record the quality attributes of the data. They are process time variables and their setting can determine which values participate in a computation and how that computation proceeds. The DQI concept has been implemented in two large database systems. The results indicate that DQI simplifies programming, storage allocation, and control over the data processing. The paper conjectures how this concept can lead to the solution of a major data processing problem, that of production control, that lies in the foreseeable future.
