If the user has authority to do so, they can access via the DBMS software itself. However, typically their access is either via an application that controls it or thru forms in a user GUI.
A database management system (DBMS) is responsible for providing users with access to appropriate data in a database. The DBMS controls user access permissions, enforces security measures, and manages queries to ensure users can retrieve the data they are authorized to access.
The five components of a DBMS are hardware, software, data, procedures, and users. Hardware includes the physical devices where the database is stored and processed, while software refers to the actual DBMS program. Data represents the information stored in the database, while procedures define how tasks are carried out within the system. Users interact with the system to input, retrieve, and manipulate data. These components work together to manage and maintain the database effectively.
DBMS (Database Management Systems) are important in an information-based society because they provide a structured way to store, manage, and retrieve data efficiently. They help in organizing and maintaining large volumes of data, ensuring data consistency and integrity, and enabling quick access to pertinent information. DBMS also support data sharing and collaboration among users, leading to enhanced decision-making processes and overall business performance.
Remove all redundancy from database using Normalization to ensure almost purest form of data base is called abstraction. literally abstraction is a process of removing unnecessary information from database. it hide super flush information form database and gives emphasis on valuable information.
-data redundancy:which reduce the redundancy-repetition of data -security-it provides security for various levels -data sharing-it allows multiple users to access and share the data becomes easier in dbms -data concurrency:it allow multiple users to acess the same data simultaniously
DataBase Management System (DBMS)is a software package# it allows data to be effectively stored, retrieved and manipulatedand # the data stored in a DBMS packege can be accessed by multiple users and by multiple application programs like (SQL Server, Oracle, Ms-Access) .Types of DBMS# Hierarachical DBMS (HDBMS)# Network DBMS (NDBMS)# Relational DBMS (RDBMS)# Object Oriented DataBase(OODB)# Distributed DBMS (DDBMS)
DBMS is database management. Database is where the information is stored.
A database management system (DBMS) is responsible for providing users with access to appropriate data in a database. The DBMS controls user access permissions, enforces security measures, and manages queries to ensure users can retrieve the data they are authorized to access.
In DBMS you can have users who have only select access or with only select+update+insert access or with select+update+insert+delete access. These users may or may not be granted permissions to alter the table schema. Also you can have administrators who can create/modify/delete tables

Data represents the information stored in the database, while procedures define how tasks are carried out within the system. Users interact with the system to input, retrieve, and manipulate data. These components work together to manage and maintain the database effectively.
In DBMS the data is stored in the form of table . Each row in DBMS is known as tuple.
SQL (Structured Query Language) is the language used by most DBMS (Database Management Systems) to help users access data. It allows users to perform tasks such as querying databases, manipulating data, and managing database structures. SQL is a standardized language that is widely used in the industry.
Primarily it's based on rules about when changes to data are posted in a transaction and read by other users, which are part of the record-locking features of the DBMS. Some DBMS's manage this with undo and redo logs, which support snapshotting the data before the updates were started, so that other users can access the records before the update transaction was started.
What is the purpose of dbms?DBMS is a software that organises the creation, storage and maintenance of Databases for end users.
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.
