Which is better file system or database?
File processing system has more data redundancy, less data redundancy in dbms. File processing system provides less flexibility in accessing data, whereas dbms has more flexibility in accessing data. File processing system does not provide data consistency, whereas dbms provides data consistency through normalization.
Why database system is better than file system?
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. Concurrent access to data means more than one user is accessing the same data at the same time.
Where do you store logs?
Preferably, logs should be placed on wooden pallets as these keep them off the ground and provide a free flow of air underneath; the ideal height of the wood stack (including the pallet) should be no more than 3ft (1m) as the logs can become unstable if piled too high.
Which is better file system or database management system?
The file system offers lesser security. Database Management System offers high security. File System allows you to stores the data as isolated data files and entities. Database Management System stores data as well as defined constraints and interrelation. Not provide support for complicated transactions.
Can a service log to a file system?
On the OS layer you can do logging but you really only have the file system available. Services can log to file system, but they cannot trust other services to be running so they cannot log there. Applications can log to services and the file system.
How is redundancy controlled in a file system?
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. There may be a possibility that two users are maintaining same files data for different applications.
How is data stored in a file system?
A File Management system is a DBMS that allows acces to single files or tables at a time. In a File System, data is directly stored in set of files. It contains flat files that have no relation to other files (when only one table is stored in single file, then this file is known as flat file).
