Answer: I prioritize data quality by validating sources, performing data integrity checks, and creating validation rules to ensure accurate reporting. Additionally, I conduct regular audits and reviews of the reports to identify any discrepancies and address them promptly. I also involve stakeholders in the validation process to ensure that the reports meet their requirements.
5) How do you stay updated with the latest trends and advancements in business intelligence?
Answer: I regularly attend industry conferences, webinars, and training sessions to stay informed about the latest trends in business intelligence. I also participate in online communities and forums to exchange knowledge and insights with other BI professionals.
