You can use the same and create a simple GUI, that would look like the following one. When you understand that the problem is in the data access layer. For example, in the database you’ve allowed null entries, so now spam users would be able to leave the data inconsistent and cause a problem of redundancy. You can edit the data access layer, so that you can define the columns to not have null values. This sets up a condition of validation, because the stream of data is always validated on the controller. That is why it makes the data more consistent by removing any chance of invalid data entry or unauthorized data deletion from the application’s data source.
The model component contains the logic responsible for retrieving data from the database. For this, you can also use a JSON file in place of a database. Thus, you can consider MVC Framework as a major framework built on top of ASP.NET providing a large set of added functionality focusing on component-based development and testing. The View component is used for all the UI logic of the application. For example, the Customer view will include all the UI components such as text boxes, dropdowns, etc. that the final user interacts with.

Otherwise, just follow the concept of «first package in the application». The class file in this package would be located under the package, open it. This way you don’t need to scratch your head once your application reaches an enterprise level mvc programmer and your source code looks a bit messy and cannot be debugged. This way you can control, develop, debug, or add features to all of the layers separately. In this short section, I will try to provide a basic overview of the MVC framework.
In this article, I will dive deep into what MVC means alongside its 3 components, so you can understand it. Ideal for developing complex but lightweight applications.
