Model: Model is responsible for managing and controlling all data linked with the database, So with the help of models, we can perform all CRUD operations on DB. It allows us to retrieve any kind of data from DB via query and also all functions related to the management of data are written in the model. so you can call the functions for a specific query multiple times without rewriting the same query. View: The view section of code is responsible for managing views in implanting layout and design. and also put the data in the view that is passed to it.
