File System: File system is a method and structure that an operating system uses to keep track of files on the disk. This is the way files are organised on the disk.
Database System:
Database system is a high level definition of structure and relationship between stored data, a database or databases, users and the hardware or operating system used for the storage
Merits of file system:
Demerits of File system:
Data Isolation: Because data are scattered in various files, and files may be in different formats, writing new application programs to retrieve the appropriate data is difficult.
Duplication of data – Redundant data
Dependency on application programs – Changing files would lead to change in application programs.
Merits of database system:
· No redundant data – Redundancy removed by data normalization
· Data Consistency and Integrity – data normalization takes care of it too
· Secure – Each user has a different set of access
· Privacy – Limited access
· Easy access to data
· Easy recovery
· Flexible
Demerits of Database system:
· DBMS implementation cost is high compared to the file system
· Complexity: Database systems are complex to understand
· Performance: Database systems are generic, making them suitable for various applications. However this feature affect their performance for some applications
