if we need a modifying ,sreach,delete a file so we need a DBMS
In DBMS Multiple user can access file at a time. but in flat file system only one user can access file at a time

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.
A Database Management System (DBMS) is a software that allows for efficient organization, storage, and retrieval of data in a structured manner. It provides features like data integrity, security, and concurrency control. In contrast, a conventional file system is a basic system for storing and retrieving files in a hierarchical structure, lacking the advanced functionalities of a DBMS.
Yes. Database Management Systems (DBMS) have replaced the traditional file based data storage systems. This is because they are:More powerfulEasier to manangeCan store large volumnes of dataManipulation & fetching of data from a DBMS is many times easier than doing so from a file based data storage systemFaster
Yes! The master file of a DBMS is a data file containing relatively permanent records that are generally updated periodically. The transaction file is a temporary file that holds all changes to be made to the master file, such as additions, deletions, and revisions. A transaction file has to be sorted before it is used to update the master file. By the way, I didn´t get your question, but I hope I helped =D

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.
to have a data file with multiple access path is known as multi key file organization
A DBMS is used to store data in an organized manner in a way that is later easy to retrieve. Compare 1,000,000 emails stored as plain text files, or the same 1,000,000 emails stored in a DBMS. In the former, each file would have to be opened by a person or a script to find specific content, which could take hours or even days, while a DBMS can find that information in seconds. Even better, DBMS can observe trends easily, such as how many emails per day were sent by Jane Doe, or how many emails contained a specific keyword or phrase, and when was the first and last occurrence of that keyword. DBMS is not without drawbacks, however. For example, it does not make sense to have a file system completely inside a DBMS, because that file system would run slower than a normal table-based system. However, a DBMS can be used alongside the table-based file system in order to boost search performance (Windows does something similar to this). Use a DBMS if you want to be able to determine data trends, relationships, and other database-driven concepts. Otherwise, a normal file will suffice.
