Spring MVC Any application consists of three layers those are: 1\. Presentation layer : this layer of an application deals with user interaction with the application. 2\. Business logic : this layer of an application deals with data processing and database connectivity. 3\. Database layer : this layer of an application deals with data management and data storage.
