Performance degradation is a problem we face on a daily basis. We could put effort to make the application blazing fast, but we soon end up where we started. It’s happening because of new features being added and the fact that we sometimes don’t have a second thought on packages that we constantly add and update.
Models are classes that define the properties of a particular data to be stored in a database. For example, if we have a user model, we would define the properties of a user for our application such as name, email, and so on. So each time we want to create a new user, we use the user model we’ve defined.
