태블로 자격증이란?
태블로 자격증은 데이터 시각화 도구인 태블로(Tableau)를 사용하는 능력을 검증하는 시험입니다.
태블로 자격증의 종류
태블로 자격증에는 Desktop Specialist, Desktop Certified Associate, Desktop Certified Professional, Server Certified Associate, Server Certified Professional 등 다양한 종류가 있습니다.
일반적으로 Desktop Specialist를 많이 취득하는 것으로 알고 있고 저도 이 자격증을 준비하고 있어요.
태블로 자격증을 보유하면 데이터 시각화에 대한 전문성을 인증받을 수 있으며, 취업에도 큰 도움이 됩니다.
