Database Management Systems, or DBMS, are software applications specially designed to interact with the user and other applications, as well as the database itself, to analyze data. All files in a software have file name extensions to identify their file types. For memory files .mem is the file name extension.
A flat file is a simple file containing data without any structured format, while a Database Management System (DBMS) is a software system that manages databases by organizing, storing, and retrieving data. A DBMS allows for more organized and efficient data management, supports relationships between data, and provides features like security and data integrity that are not available with flat files.
In File System, files are used to store data while, collections of databases are utilized for the storage of data in DBMS. Although File System and DBMS are two ways of managing data, DBMS clearly has many advantages over File Systems. Typically when using a File System, most tasks such as storage, retrieval and search are done manually and it is quite tedious whereas a DBMS will provide automated methods to complete these tasks. Because of this reason, using a File System will lead to problems like data integrity, data inconsistency and data security, but these problems could be avoided by using a DBMS. Unlike File System, DBMS are efficient because reading line by line is not required and certain control mechanisms are in place.
File System vs Data base Management System :- 1. Files act locally where as DBMS saves directly in a database 2. Saves in temporary locations where as DBMS in well arranged and permanent data base locations 3. In File System., transactions are not possible where as various transactions like insert, delete, view, updating etc are possible in DBMS 4. Data will be accessed through single or various files where as in DBMS, tables (schema) is used to access data. 5. A "File manager" is used to store all relationships in directories in File Systems where as a data base manager (administrator) stores the relationship in form of structural tables 6. Last.... but not the least.... Data in data bases are more secure compared to data in files!!
Hierarchical DBMSNetwork DBMSRelational DBMS
because DBMS consist of interrelated data field which can be identified through a unique keys in identifying a record to know the origination of data source that serve as an object in the table column in database.
file organization
if we need a modifying ,sreach,delete a file so we need a DBMS
What is the file extension What is the file extension
In DBMS Multiple user can access file at a time. but in flat file system only one user can access file at a time
file extension for video is 101

The file extension tells about the type of file, with the extension three letters. For Eg:- *.txt -- text file *.exe-- executable file
file extension
