Backend Database

January 31, 2023

A backend database is a structured system that stores and manages data for a backend application. It is responsible for storing and retrieving data and enforcing data integrity and security. Backend databases are typically used in conjunction with a backend application to provide a way to persist data and make it available to the application for various operations such as creating, reading, updating, and deleting (CRUD).

Types of backend databases, such as:

Relational databases: Such as MySQL, MariaDB, and PostgreSQL, store data in tables with rows and columns and use SQL (Structured Query Language) for querying and manipulating data.

Non-relational databases: MongoDB, Cassandra, and Redis, which store data in a more flexible format, such as JSON or key-value pairs, and use different querying languages.

Cloud databases: Such as Amazon RDS, Azure Database, and Google Cloud SQL, which are databases that run on cloud-based infrastructure and can be easily scaled up or down as needed.

The backend developer is responsible for designing the database schema and queries and ensuring that the database performs well and is secure. They also need to ensure that the database can handle the expected amount of data and traffic and can be scaled up or down as needed.
