Defining CRUD

When you define a service to send and receive data, this object should usually perform a minimum level of behavior. You can identify this behavior through the acronym CRUD:

• Create (C): You need to send a message to the server with a new object to persist it in a database. The HTTP POST verb is used for such requests.
• Retrieve (R): The service should be able to send a request to get a collection of objects or just one specific object. The GET verb is used for such requests.
• Update (U): This is a request to update an object. By convention, the PUT verb is used for such requests.
• Delete (D): This is a request to delete an object. The DELETE verb is used for such requests.

More operations can be implemented, and sometimes you do not need to code all CRUD methods. You should adapt your code to the application requirements and define only operations that the application needs. Remember that writing more code than the application needs means creating the possibility of writing more errors...
