CRUD
CRUD is an acronym for Create, Read, Update, and Delete, representing the four basic operations of persistent storage in software applications. It is a foundational concept in database management, API design, and web development, describing the essential actions performed on data entities. CRUD operations are typically implemented in relational databases, NoSQL databases, and RESTful APIs to manage data lifecycle.
Developers should learn CRUD because it underpins nearly all data-driven applications, from simple web forms to complex enterprise systems. It is essential for building RESTful APIs, where CRUD maps to HTTP methods (POST, GET, PUT/PATCH, DELETE), and for database interactions using SQL or ORM tools. Understanding CRUD helps in designing efficient data models, ensuring data integrity, and implementing user interfaces for data management.
