A Metadata-Driven Application Rapid Development Engine Design and Implementation

The current mainstream metadata engines have weak support for the rapid development of universal applications, and their model abstraction capabilities mainly focus on one or several similar or similar business domains. The more universal domain model abstraction capabilities are insufficient. In addition, the current mainstream metadata engines are difficult to achieve effective separation between data models and data operations. The strong coupling between data models and data operations leads to the need to rewrite data operation code once the data model changes. A new system development method has been proposed, The purpose of this paper is to provide a metadata driven application rapid development engine that fully covers the entire software development lifecycle. The engine can solve the contradiction between rapid changes in application software requirements and slow system development response, and has stronger domain adaptability, capable of completing rapid development work for various types of applications; The development of abstraction and client applications can be achieved through the definition of domain meta models and domain model instances; In addition, the engine supplements and improves the shortcomings of the MVC model in decoupling data models from data operations by introducing a data mapping layer, greatly enhancing the flexibility of data operations and improving the reusability of code..
