Which of the following has the GREATEST influence on data quality assurance?

Data stewardship involves managing data assets, which is critical for quality, but it relies on an understanding of data classification to apply appropriate and effective stewardship efforts.

Data encryption protects data confidentiality and integrity, which are aspects of data security, but not the primary driver for overall data quality assurance, which includes accuracy, completeness, and timeliness.

Data classification has the greatest influence on data quality assurance because it establishes the basis for how data should be handled, protected, and governed throughout its lifecycle. By classifying data based on sensitivity, criticality, and regulatory requirements, an organization can apply appropriate controls, validation rules, and stewardship efforts that directly impact its accuracy, completeness, and reliability.

Data modeling designs the structure of data, which contributes to quality by ensuring consistency, but classification informs *how* that structure needs to support quality based on its business value and sensitivity.
