What is the purpose of data validation rules during import?

• A. To Delete All Imported Data
• B. To Export Data To External Systems
• C. To Change User Passwords
• D. To Ensure Data Quality By Detecting Duplicates And Invalid Mappings

Answer: (D)

Data validation rules during import focus on protecting data quality as records enter the system. They ensure each imported record fits the expected structure and business rules, including that required fields are present, values have the correct types and formats, and mappings from the import file align with the system’s fields. A crucial part is identifying duplicates so you don’t create multiple records for the same entity, and spotting invalid mappings where a column in the file is assigned to a non-existent or inappropriate field. When issues are found, records can be rejected or flagged for correction, preventing bad data from polluting the database and causing future problems. These checks aren’t about deleting data, exporting data, or changing passwords, which are outside the import validation scope.
