Question 1 of 25

Explain the difference between a database manager and a data manager?

"The difference between a database manager and data managers is fundamental. Data management is the process of using data to manage an operation, run a business, or solve an issue. Anybody can be a data manager if they use data to make decisions. Database management, on the other hand, is managing the underlying structure of the data, which is organized and stored in a database. Database managers don't use the data they manage for decision-making, except to define data tables, create queries, or when working with other database management tools."
