Method and system for model-driven development

Abstract

The present disclosure relates to methods and systems for model-driven development. In one embodiment, there is provided a method for model-driven development, comprising: analyzing program code to determine an execution order of statements of the program code, the program code being generated by performing a first transformation on a model, the a model comprising an abstract description of a business implemented by said program code; grouping at least a portion of said statements of said program code into function blocks; creating a visual representation of said program code based on said order of execution and said function blocks and determining a code segment to be retained in the program code based on the user's annotation of the visual representation, the code segment to be retained in the new program code generated by performing the second transformation on the model, the The second transformation is performed after the first transformation. A corresponding system is also described.

Description

technical field

[0001] Embodiments of the invention relate generally to program development, and more particularly, to methods and systems for model-driven development. Background technique

[0002] Model Driven Development (Model Driven Development, MDD) is an efficient program development model. For example, various models such as a business rule model (Business Rule Model) may be used to provide abstract definitions for applications or services. For example, a model can define the rules or logic of a business. It is known that such models can be converted into executable program code. As an example, Java code can be generated by converting an EMF (Eclipse Modeling Framework) model. By using the model and its transformation, the logic and rules of the application to be developed can be decoupled from the underlying program code, which is conducive to improving the flexibility of program development and maintenance.
