CRUD programming - a Brief

CRUD is an acronym that stands for Create, Read, Update, and Delete. These are the four basic operations that can be performed on data in a persistent storage system, such as a database.

Here's a breakdown of each operation:

• Create: This operation adds new data to the system. For example, creating a new user account or adding a new product to an online store.
• Read: This operation retrieves data from the system. For example, viewing a list of users or displaying the details of a specific product.
• Update: This operation modifies existing data in the system. For example, changing a user's password or updating the price of a product.
• Delete: This operation removes data from the system. For example, deleting a user account or removing a product from an online store.

CRUD operations are fundamental to many computer applications. They are used in a wide variety of contexts, including:

• Relational databases: CRUD operations are the basis of SQL, the standard language for interacting with relational databases.
• Web applications: CRUD operations are used to manage data in web applications, such as creating, reading, updating, and deleting blog posts or user profiles.
• Mobile applications: CRUD operations are used to manage data in mobile applications, such as creating, reading, updating, and deleting contacts or tasks.

In addition to being used in software development, CRUD is also a useful concept for understanding how data is managed in general. For example, when you create a new document in a word processor, you are performing a create operation. When you open a document to view it, you are performing a read operation. When you edit a document, you are performing an update operation. And when you delete a document, you are performing a delete operation.

Overall, CRUD is a fundamental concept in computer programming and data management. It is a simple but powerful framework for understanding how data is created, read, updated, and deleted.
