A single aspect of data quality is defined as a ¡°dimension¡± such as ¡°consistency¡±, ¡°accuracy¡±, ¡°completeness¡±, or ¡°timeliness¡±.

Data quality methodologies are sets of guidelines and techniques that are designed for measurement assessment, and perhaps, improving data quality in a given application or organization.
