What is CRUD?
Organizations that maintain customer records, payment information, health data, and more need persistent data storage platforms. This data is usually organized into a database, which is simply an organized collection that can be viewed electronically. The most common type of database is a relational database, which consists of rows and columns linked to other tables with additional information using a keyword system.
CRUD is an acronym that refers to the four main functions required to implement a persistent storage software: create, read, update, and delete.
CRUD is widely used in databases. This includes relational database management systems (RDBMS) such as Oracle, MySQL and PostgreSQL. It also includes NoSQL databases such as MongoDB, Apache Cassandra, and AWS DynamoDB.
Users can call four basic CRUD functions to perform different types of operations on selected data in the database. This can be done through code or through a graphical user interface.
Typically, CRUD consists of 3 parts: an API (or server), a database, and a user interface (UI). The API contains code and methods, the database stores and helps the user retrieve information, while the user interface helps users interact with the application.
