How do constraint-based data validation techniques differ from rule-based techniques in ETL?

  • Constraints and rules are synonymous in ETL
  • Constraints are dynamic conditions, while rules are predefined limits
  • Constraints are predefined limits, while rules are dynamic conditions
  • Constraints focus on data transformation, while rules focus on extraction
Constraint-based data validation techniques rely on predefined limits, such as data type and length constraints. Rule-based techniques, on the other hand, involve dynamic conditions that adapt to specific situations during the ETL process.
