Prototype Program Development Mode

Prototype program development mode

---"Scenario Develop a prototype system in a
　　short time for business or technical personnel to demonstrate to Party A.
---"Development
　Mode There are three modes:
* Mode 1: The overall consideration drives
  the control from the overall demand, the division of modules, etc., and implements the overall research and development of the project.
* Mode 2 back-end (station) driver The development of the entire project is driven
　　by the database and model design as the main line.
* Mode 3 Front-end (UI) driver
   takes UI design as the main line, designs and implements modules, and data display content to promote the overall research and development of the project.
---"Pros and cons and selection
   mode One is the ideal state, which requires domain experts with rich knowledge, clear requirements, and overall control of the project. However, it is difficult to implement when time and personnel (resources) are limited;
   mode 2 considers the content (data) implemented by the front-end from the back-end. It can better reflect which modules can be implemented and those module data (resources) are not available. The disadvantage is that it may take too much time to realize the back-end interface, but many functions of the front-end are not realized.
   Mode 3 is front-end driven, and the required data and functional modules are planned and processed while designing the UI. For business or technical personnel to quickly see the function implementation, these modules may not be complete (the data may be simulated). Failure to fully consider the overall implementation may result in a situation where the backend cannot be implemented.
