All of the 200 level codes are generally positive status codes:
• 200 (ok)
• 201 (created)
• 202 (accepted), etc.
By contrast, 400 level status codes generally indicate an issue with the request itself, and 500 level status codes generally indicate an error on the back-end.
If the initial request has been accepted by the web application server, and there is a need to retrieve data related to the request, the web application server then queries a database or databases to get the information needed to send back to the user.
The database sends the result of the query back to the web application server, and then the web application server usually formats the data into a format to be sent back to the front-end. JSON (JavaScript Object Notation) is a very common format currently used to send data to clients (the front-end).
