Mell What are file system problems?
The file system’s structure makes it difficult to combine data from multiple sources, and its lack of security renders the file system vulnerable to security breaches. The organizational structure promotes the storage of the same basic data in different locations. The different problems with data redundancy are: i.
What is the main problem or limitation of a file based system?
Security can be a problem with a file-based approach because: There are constraints regarding accessing privileges. Application requirements are added to the system in an ad-hoc manner so it is difficult to enforce constraints.
What is integrity problem in file system?
Integrity problems It refers to the maintenance and assurance that the data in a database are correct and consistent. Data values must satisfy certain consistency constraints that are specified in the application programs.
Which is not advantage of DBMS?
one of the disadvantages of dbms is Database systems require sophisticated hardware and software and highly skilled personnel. The cost of maintaining the hardware, software, and personnel required to operate and manage a database system can be substantial.
Why size is disadvantage of DBMS?
Cost of Hardware and Software – This is the first disadvantage of the database management system. This is because, for DBMS, it is mandatory to have a high-speed processor and also a large memory size. After all, nowadays there is a large amount of data in every field which needs to be store safely and with security.
What is integrity problem?
Data integrity may be compromised through: Human error, whether malicious or unintentional. Transfer errors, including unintended alterations or data compromise during transfer from one device to another. Bugs, viruses/malware, hacking, and other cyber threats. Compromised hardware, such as a device or disk crash.
What is Disadvantages of DBMS?

What are the advantages of file based system?
Advantage of File-oriented system: 1. Backup: It is possible to take faster and automatic back-up of database stored in files of computer-based systems. computer systems provide functionalities to serve this purpose.it is also possible to develop specific application program for this purpose.
What is the major disadvantage of file processing system?
The file processing system has the following major disadvantages: Data redundancy and inconsistency. Integrity Problems. Difficulty in accessing data. Data isolation.
What are the advantages of DBMS over traditional file system?
The principal advantages of DBMS over file processing system: • Flexibility: Because programs and data are independent, programs do not have to be modified when types of unrelated data are added to or deleted from the database, or when physical storage changes.
What is the difference between a file system and a database?
A File System is a collection of raw data files stored in the hard-drive, whereas a database is intended for easily organizing, storing and retrieving large amounts of data. In other words, a database holds a bundle of organized data typically in a digital form for one or more users.
