Concepts Overview CK-DQS Relationship:

CK (Check System) ensures the accuracy, consistency, and completeness of data handled by the Data Quality System (DQS).

It introduces validation checkpoints at different stages of data handling (e.g., data entry, ETL processes) to enforce quality standards.

DQS-DQ Relationship:

The Data Quality System (DQS) is responsible for monitoring, profiling, and correcting data to align with desired Data Quality (DQ) standards (e.g., correctness, completeness, timeliness).

DQS feeds quality reports to stakeholders and triggers remediation workflows if data falls below set thresholds.
