A General Software Modeling Method for Constructing Software Model Based on Software Metamodel

Abstract

The invention discloses a general software modeling method for constructing a software model based on a software meta-model. 1. The software transmission model is a step element to construct a software model, which provides software modeling specifications with the advantages of operability, versatility, and ease of use for various fields: the software model constructed by the present invention has a clear structure, adjustable levels, and controllable modeling granularity , has sufficient consistency that can be calculated; the method is unified, not only convenient for top-down analysis and design, but also convenient for bottom-up integration, suitable for modeling of various software systems; the number of modeling elements is small, and the modeling method is simple. Even ordinary field personnel who do not understand modeling language and computer programming language can independently and easily construct software models, eliminating the need to rely on and communicate with professional modelers or program developers, and the modeling time is greatly shortened.

Description

technical field [0001] The invention relates to the technical field of software engineering, in particular to a general software modeling method and a computer program product for constructing a software model based on a software meta-model. Background technique [0002] In today's highly developed information technology, software plays an increasingly important role in human life and development. After the software method has gone through the development stages of function-oriented and process-oriented, the object-oriented software method has become quite mature and has become the current mainstream software method. As software systems become more and more complex, object-oriented methods expose more and more deficiencies, and model-driven methods become the ideal software design methods that people pursue. The core idea of ​​the model-driven software method is: developers focus on constructing software models, express knowledge as software models, and hand over the work o...

Problems solved by technology

Unfortunately, UML has the following defects: First, non-operational: UML claims to provide a lot of flexibility for creating models, but its essence is that due to the lack of rigorous theoretical support, it is impossible to guarantee that a sufficiently complete consistency can be obtained by using UML. sex model

The software model constructed using UML is not operable, that is, it lacks sufficient and consistent information that can be automatically converted into computer-operable software by using automatic code generation technology. To obtain computer-operable software, it must be edited manually in the form of code. ; This defect also makes UML only an auxiliary representation tool for software models, but not a real software metamodel; second, code-oriented: Although UML claims to be a model description language independent of specific languages ​​and platforms, but In essence, UML is basically an expression tool for programmers to use object-oriented programming language for program analysis and design

This code-oriented feature for programmers makes "emphasis on implementation and neglect of business" a chronic problem in the software development industry

Third, it is difficult to use: UML creates concepts, a large number of relationships and a large number of diagrams

From the point of view of software modeling, first, the ontology meta-model focuses on knowledge management and information sharing, not general software modeling; second, the ontology meta-model adopts a complicated formal language, which is not easily Mastery of field personnel

[0005] In general, although the model-driven method is generally recognized as an ideal software development method, there is still a lack of a software meta-model that is easily understood and mastered by ordinary people in the field, and provides a general software modeling specification. , to support software modeling activities in various fields to construct operable software models, so that the software models can be automatically converted into software that can be run by the computer through automatic code generation technology, so that the model-driven software method can be implemented
