A database (DB) is an organised and structured set of data that is stored and managed in a computer system.
A database can be used to store and manage information of various types, such as telephone numbers, email addresses, financial records, medical records, among others.
In a database, data is organised into tables or relationships, which contain columns or fields that describe different characteristics of the data, and rows that represent each of the individual records in the database.
Databases can be managed and queried using database management software, such as MySQL, Oracle, Microsoft SQL Server, MongoDB, among others. These tools allow users to create, update, search and delete data efficiently and securely, and also provide mechanisms to ensure the integrity and security of the stored data.
