What is a primary advantage of using a database management system (DBMS) instead of a flat file system in an environment with multiple simultaneous users?
A DBMS includes concurrency control mechanisms to manage simultaneous access.
Flat files can only be edited using specialized software.
A DBMS is less expensive to set up and maintain.
Flat files provide faster data processing for all types of queries.
A primary advantage of a database is its built-in support for concurrency, which allows multiple users to access and modify data at the same time without causing data corruption or inconsistencies. DBMSs use concurrency control mechanisms, such as locking, to manage these simultaneous operations safely. In contrast, flat file systems lack these mechanisms, and simultaneous access can lead to errors or data integrity issues. While a DBMS can be more complex and costly than a flat file system, and performance can vary by use case, its ability to handle concurrent users is a key differentiator.
