Why in the illustration does the Model Point to the View,

… if the Model sends data back to Controller to send to the view, shouldn’t the Arrows be Model <–> Controller <–> View?

The arrows in the MVC architecture diagram indeed represent the flow of data and requests between the different components. However, the direction of the arrows can vary depending on the specific interaction being depicted.

In the typical flow of a user request in MVC:

  1. The View interacts with the Controller to handle user input and send requests.
  2. The Controller communicates with the Model to retrieve or manipulate data.
  3. The Model processes the data and sends it back to the Controller.
  4. The Controller then passes the data to the View for rendering.

So, in essence, the flow can be represented as:

View → Controller → Model → Controller → View

However, in some cases, such as updating data, the flow might be:

View → Controller → Model → View

It’s important to note that the direction of the arrows may vary based on the specific scenario being illustrated. The key concept is that the Controller acts as an intermediary between the View and the Model, facilitating communication and data flow between them. If you have any further questions or need clarification on any aspect of MVC architecture, feel free to ask!
