if we need a modifying ,sreach,delete a file so we need 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
Database Management Systems (DBMS) address the limitations of file-based systems by providing centralized data management, which reduces data redundancy and inconsistency. They offer structured data organization through tables and relationships, allowing for efficient querying and retrieval. Additionally, DBMS implement data integrity and security measures, ensuring that data is accurate and accessible only to authorized users. Overall, DBMS enhance data manipulation, scalability, and maintenance compared to traditional file systems.
Prior to the use of DBMS Traditional file processing system were in use . These were the system that are used as database that time. These system do not supports the query.
Traditional file processing system lacks from DBMS in many ways . Major Disadvantage of FPS are it do not maintains data security and integrity efficiently.
Traditional FPS and DBMS both are different from each other. In DBMS there is security of data as well as integrated data while this is not in FPS.
file organization
In DBMS Multiple user can access file at a time. but in flat file system only one user can access file at a time

using with files
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 File Management System (FMS) organizes and manages files in a hierarchical structure, focusing on file storage, retrieval, and basic operations like creation and deletion. In contrast, a Database Management System (DBMS) provides a more advanced structure for managing data, allowing for complex querying, data relationships, and multi-user access. DBMS ensures data integrity, security, and supports transaction management, while FMS lacks these capabilities. Essentially, a DBMS is designed for more sophisticated data handling compared to an FMS.

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

explain error handling during file operation?
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.
