A Visual Modeling Editor for Constructing System Models

Abstract

A visual modeling editor for constructing a system model on the basis of a system meta-model comprises a hierarchy editor, an interface editor, an algorithm editor, a flow editor and a transmission editor as components, and completes editing of the system model and system views by taking a hierarchy model, an interface model, an algorithm model, a flow model, a transmission model and corresponding views respectively as edited objects, thus a versatile and easy-to-use visual system modeling tool is provided for a wide variety of fields. The system model and system views are executable, clear in structure, adjustable in hierarchy and controllable in modeling granularity; the modeling method facilitates not only top-down analysis and design, but also bottom-up integration, and also is applicable to the modeling of various system software systems and information systems; the modeling method is simple and totally visual in modeling, and even a person skilled in the art can edit the system model and system views independently and easily.

Description

technical field [0001] The invention relates to the technical field of software engineering, in particular to a visual modeling editor for constructing system models. Background technique [0002] System modeling is an activity or process in which people construct system models according to the laws and characteristics of objective things. System modeling has been widely used in various social practice activities such as scientific research, engineering, military affairs, and production. Today, with the high development of information technology, especially software technology, software has become the basic tool for people to carry out system modeling. These software tools that assist in system modeling are called modeling editors. Compared with modeling editors in the form of words, formulas, and formal languages, modeling editors using graphics have become people's favorite because of their visibility. Such graphics-based modeling editors are called visual modeling edit...

AI Technical Summary

Problems solved by technology

Based on UML, these modeling tools naturally have defects brought by UML: first, lack of modeling method support: these tools do not provide modeling methods and rules, but only provide some symbolic representation tools; these tools are program-oriented The software development process modeling used by developers actually focuses on the description of the program implementation model based on the object-oriented method, and is not suitable for general system modeling editors beyond software development

Second, non-computational: the system model constructed by these tools is not complete and consistent enough to be converted into computer-runable software by automatic code technology

This type of assembly visual modeling editor based on prefabricated components has two basic defects: it must be assembled based on prefabricated components, and the construction of the system model is severely restricted by prefabricated components; the interface of prefabricated components is fixed, because it does not support any interface Component integration, this kind of visual modeling editor is usually applied to specific domain modeling based on domain component library, so it is not suitable for general system modeling; second, the principle of component assembly and operation is also very simple, Based on the fact that the data transfer relationship determines the work coordination of components, and at the same time, with the increase of components, the complexity of data transfer makes the view readability sharply deteriorates. Therefore, although this type of editor claims to perform system modeling, But it is actually used to model simple and clear algorithms, not suitable for large and complex system modeling;

[0005] In general, there is still a lack of a visual modeling editor for constructing system models that is easily understood and mastered by ordinary domain personnel. Based on general system modeling specifications, it supports various domain modeling activities to construct Computable System Model
