The insert() method is useful when you need to insert multiple records at once. For instance, if you need to import a large dataset into your application, you can use the insert() method to add all the records at once, instead of making multiple calls to the database. On the other hand, the create() method is useful when you need to create a single record and persist it to the database in a single call. This is often the case when you are creating a new user account or adding a new item to a shopping cart.The insert() method is useful when you need to insert multiple records at once.
