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
What else can I help you with?
What is master file in database environment?
The main file in the database which is the only copy of the important data in a database is MASTER FILE lalkesav@gmail.com
What is difference between database management system and file 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 r possible in DBMS 4. Data will be accessed through single or various files where as in DBMS, tables is used to access data 5. A "File manager" is used to store all relationships in directories in File System where as a data base manager (administrator) stores the relationship in form of structural tables 6.Data in DB are more secure compared to data in files!!
What are advantage of DBMS over FMs?
Database Management Systems (DBMS) offer several advantages over file management systems (FMs). Firstly, DBMS provide better data integrity and consistency through constraints and relationships, reducing redundancy. Secondly, they enable efficient data retrieval and manipulation using structured query languages, making it easier to handle complex queries. Lastly, DBMS support concurrent access and transaction management, allowing multiple users to interact with the database simultaneously without data conflicts, which is a significant limitation in traditional file management systems.

What is the difference between flat file and DBMS?
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.
DBMS has replaced the traditional file system?
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
Which two file are used during the operation of dbms?

What is the extension of memory file in DBMS?
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.
How DBMS overcome problem of file based system?
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.
Why would use DBMS to store data?
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.
What is the difference between database and file system?
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.
