What is database management?
Database Management is a field of study that deals with the structure and control of information, and the ability to search, sort, and retrieve data on a computer.
The term was coined in 1965 by Edgar F. Codd, who worked for IBM. It was first used in the context of databases.
A database is a collection of information that can store and organize data. A database consists of tables that have rows and columns. Each row represents a single record, and each column represents a single field. This is why we say that database is the backbone of the computer. When you store all the data in a single place, you can easily use it for multiple purposes.
Every system has its database to store the data and is used to keep the information in text, numbers, images, etc. If the database has been corrupted or you want to save the data in the new database, you will need to take the backup of the old database.
There are several reasons why you will require the backup of the old database. Some of the significant reasons are:
To check the integrity of the database
Sometimes you will lose your important data due to technical problems and if the database has been damaged then you need to restore the database using the backup.
To recover the deleted data
Deleting the data from the database is a common problem most users face. Sometimes it happens due to the wrong actions taken by the user, and if the user wants to recover the deleted data, then he/she will need to take the backup of the database.
To perform the data migration
Data migration is the process of moving data from one database to another database.
To perform the schema change
The schema change is the process of modifying the database structure, and the data is moved to the new database.
How does the database work?
The database stores and manages the data. The data is stored in an organized form, making it easy to access.
There are many types of databases available. They are classified as Relational Database, Hierarchical databases, and Object-Oriented Database.
