Explanation:
The job roles define differentiated tasks and responsibilities. In some organizations, the same person might perform multiple roles; so in their role as database administrator they might provision a transactional database, and then in their role as a data engineer they might create a pipeline to transfer data from the database to a data warehouse for analysis.
