What’s the difference between a DBMS and a file system?
Whereas DBMS controls redundancy by maintaining a single repository of data that is defined once and is accessed by many users. As there is no or less redundancy, data remains consistent. File system does not allow sharing of data or sharing is too complex. Whereas in DBMS, data can be shared easily due to centralized system.
Which is an example of a system call?
System Calls in Operating System Example of System Call. For example if we need to write a program code to read data from one file, copy that data into another file. The first information that the program requires is the name of the two files, the input and output files. Linux is a multi-user system, which allows many users to work on it
How is a query different from a file system?
A query causes some data to be retrieved from database. Redundancy is the concept of repetition of data i.e. each data may have more than a single copy. The file system cannot control redundancy of data as each user defines and maintains the needed files for a specific application to run.
What does a file management system call do?
