data dictionary and transaction log
What else can I help you with?
Master file in DBMS?
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
Which two files used during the operation of Rdbms?
During the operation of a relational database management system (RDBMS), two key files used are the data file or database file, which stores the actual data in tables, and the transaction log file, which records all changes made to the database to ensure data integrity and provide recovery in case of failures.
What do you mean by system file?
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.
What do you mean by file oriented system?
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.
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.
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.
What is the difference between DBMS and conventional file system?
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!!
File management system in dbms?
it was the first method used to store data in a computerized database here each field or dataitem is stored in a disk sequencily in one large file. art by mvs

Is ms access is DBMS?
No. MS Access is an application which uses a (sort of) DBMS. The power of the DBMS it uses is limited which is why it is not used for larger applications.
How a DBMS can be used?
