Difference between file system and DBMS/what is file system in dbms/
File system
A file system is a way of organizing and storing data on a computer. It consists of a set of files and directories that are stored on a computer's hard drive or other storage media. A file is a collection of data that is stored on a computer and given a name. A directory is a collection of files that are grouped together and organized in a hierarchical structure.

DBMS
A database management system (DBMS) is a software application that is designed to manage and organize data stored in a database. A database is a structured collection of data that is stored electronically and can be accessed and manipulated by computers. It typically consists of data organized into tables, where each table consists of a series of rows and columns. The rows represent individual records, and the columns represent the fields of data that are contained within each record.
Difference / list four significant differences between a file-processing system and a dbms
There are several key differences between a file system and a DBMS:
1) Data organization:
In a file system, data is organized into files and directories in a hierarchical structure. In a DBMS, data is organized into tables, which consist of rows and columns. This allows for more efficient and flexible data organization in a DBMS.
2) Data access:
In a file system, data is accessed using the file system's API or command-line interface. In a DBMS, data is accessed using SQL (Structured Query Language) or other specialized tools and functions provided by the DBMS. This allows for more powerful and flexible data manipulation and querying in a DBMS.
3) Data integrity:
In a file system, there are no built-in mechanisms to ensure the accuracy and consistency of data. In a DBMS, there are various constraints and rules that can be implemented to ensure the integrity of data, such as primary keys, foreign keys, and data types.
4) Concurrency:
In a file system, there is no support for concurrent access to files by multiple users. In a DBMS, multiple users can access and manipulate the data in the database simultaneously, and the DBMS handles conflicts and locks as needed to ensure data integrity.
5) Security:
File systems typically have limited security measures in place to protect data. DBMSs, on the other hand, often have more advanced security features, such as user authentication, access control, and data encryption.
6) Performance:
DBMSs are generally more efficient and perform better when dealing with large amounts of data compared to file systems. This is because DBMSs are optimized for data storage and retrieval and use specialized data structures and algorithms to handle these tasks.
