In this tutorial, we are going to learn about Database Management System.
Data is a collection of one-of-a-kind small bits of information. Text, numbers, media, bytes, and other types of data can all be useful to create it. We can, for example, save on paper or in an electronic memory. A database basically is a collection of data that has been organized in such a way that it can be accessed and controlled easily. A university database, for example, organizes information about students, faculty, and administrative staff, among other things, making data retrieval, insertion, and deletion simple.
Characteristics of Database Management System
It manages and stores information in a server-based digital repository.
It can depict the data transformation process in both logical and visible manner.
The DBMS includes automatic backup and recovery mechanisms.
This contains ACID properties, which ensure that data remains safe in the event of a failure.
It has the capacity to make complex data linkages easier to understand.
It is useful to aid in the manipulation and processing of data.
DBMS helps to keep data secure.
It can look at the database from a variety of angles, depending on the user’s requirements.
Advantages of DBMS:
It can regulate database redundancy since it keeps all of the data in a single database file and that recorded data is there in the database.
In a database management system, an organization’s authorized users can share data with many users.
Due to the centralized architecture of the database system, it is relatively simple to maintain.
It saves time by reducing the amount of time it takes to produce a product and the amount of time it takes to maintain it.
DBMS includes backup and recovery subsystems that produce automatic backups of data in the event of hardware or software problems, as well as restore the data if necessary.
It provides several forms of user interfaces, including as graphical user interfaces and application program interfaces.
Database Management System Drawbacks :
To operate DBMS software, you will need a fast data processor and a lot of memory.
To run them efficiently, it takes up a lot of disc space and RAM.
The database system generally adds to the complexity and demands.
Because most organizations store all of their data in a single database, failure has a significant impact on the database. If the database is damaged due to an electric outage or database corruption, the data may be lost permanently.
