Problems solved by technology

[0005] The report pointed out that despite the hype of MDA tool vendors, MDA products have little development support other than conversion or simple code generation, and because MDA is too general, the generated code is almost unusable.

Embodiment

[0093] Strictly speaking, the metadata system we developed should be MDD. The function it implements is the PSM part of MDA, and it integrates common business application patterns. From the perspective of software engineering, its function is as follows: Figure II ".

[0094] From the perspective of the role of software development, metadata mainly reduces the workload of coding, and the specific comparison can be seen Figure 5 Coding workload comparison chart:

[0095] From Figure 5 By comparison, we can find that after applying metadata in software development, software blue-collars can be eliminated (back-end business coding still requires senior programmers, which are not software blue-collars), and by using this model-driven development of metadata systems , the detailed design model we have made can maintain 100% consistency with the running system. In addition to greatly reducing the workload of coding, it can bring great benefits to testing and implementation.

Abstract

The invention provides a method for developing model-driven software capable of dynamically changing system behavior. The method is characterized in that the traditional development mode is changed; the direct operation of a model is realized; an operation system of a business object can be obtained by just using a metadata system to describe the model of the business object, without the need of the programmer encoding, so that the manner of programming codes by the programmer is changed, the substitute is that the business rules and relevant logics are edited by business experts of various industries in a graphic interface manner, and the new functions automatically become effective under the condition that the business is not interrupted.

Description

technical field [0001] The present invention is a new type of software development method, which condenses the development process of demand analysis, general design, detailed design, coding, and testing into visual modeling and partial background business coding, which simplifies the work of design, coding, and testing, and can realize streamlining Operation, quickly customize the application system, and use the import and export functions to enhance the reusability of the system, flexibly respond to changes in requirements, and improve the system's rapid response capability. Background technique [0002] The code machine technology automatically generates SQL (Structured Query Language), Java (object-oriented programming language), Jsp (JavaServer Pages), and configuration files according to the data model, and can basically generate 70% of the code. However, the code machine also has certain shortcomings. The program it generates still needs a process of release, deployme...
