This article introduces the following: • Design Pattern) This article involves the following technologies: Object-oriented and Design Patterns Introduction The design pattern is a collection of object-oriented ideas. In its classic works, gof summarizes 23 design patterns, which can be divided into three categories

controller.Third, example: BackbonePractical projects tend to take a more flexible approach, taking backbone.js as an example.1. The user can send instructions (DOM events) to view, and the view directly requires Model to change state.2. The user can also send instructions directly to the controller (changing the URL to trigger the Hashchange event) and then sent by the controller to the View.3. The Controller is very thin and only acts as a route, and the view is very thick and the business lo

The Three-tier architecture is: Presentation layer (web layer), business Logic Layer (BLL layer), and data access layer (dal layer).(1) the presentation layer is responsible for: a, collect information from the client b, send the user information to the Business service layer to do processing c, receive processing results from the Business Service layer d, display the results to the user (2) the business logic layer is responsible for: a, receive inpu

web| Data | system 　　 IntroductionIn this article I'll introduce two data-binding patterns in three-tier web system development, and then, without exceeding the knowledge of the controls you already have, introduce alternatives to--xlib library files that can drastically reduce this data-binding pattern. Specifically, this article begins with a general approach to data binding in a three-tier architecture,

　 Most of the applications we develop require a graphical user interface (GUI ). there are already many patterns in the architectural design of GUI applications. For example, Martin Fowler's Blog contains "Gui ubuntures", which describes form control, MVC, MVP, passive view, presentation Model, supervising controller, event aggregator, observer synchronization, and other modes. mode helps us build an elegant arch
