What Is a Data Management System?
Data management system refers to the administrative process of collecting, aggregating, curating, and accessing data.
Perhaps an analogy would give a clearer picture of data management and database management.
One way to differentiate data management and database management is to think of raw information as the car. As the data owner, you know how to drive the car, turn the knobs, and operate all the buttons to utilize the vehicle as it was designed. The database management, however, would be your mechanic. He knows all the nuts, bolts, and levers to make the car move smoothly. He also knows the technology and tools to improve the performance of the vehicle.
