The CTO is responsible for IT infrastructure management, software development, and other technology-related functions. A chief digital officer is limited to the digital domain and manages digital data-related tasks. The CDO also works on digital marketing campaigns under the guidance of a CMO.

CDOs focus on data management, data catalog, business glossaries, data quality, management compliance with data regulations, and analytics. At the same time, CIOs concentrate on technology and infrastructure, including information management, security, and architecture.

A Chief Data Officer, or CDO, is an executive-level position overseeing the strategy and processes of storing and managing data for a company or organization. Because this is a leadership role, to become a CDO, you'll need experience working with data and governance and leadership and management experience.
