Business variable-oriented software development scheme generation method

Abstract

The invention provides an accurate demand design and demand analysis-based business variable-oriented software development scheme generation method. The method comprises an accurate system function demand design and demand analysis stage, an accurate software function demand design and demand analysis stage, and an accurate function demand design and demand analysis stage. In the accurate system function demand design and demand analysis stage, function demands are divided into multiple function units according to original system function demand information of a user; a corresponding businesslogic variable is matched for each function unit; a corresponding discrete event is established according to the business logic variable, wherein the discrete event is used for triggering change of the business logic variable; and according to the discrete event, a demand function of the business logic variable is defined. In the accurate software function demand design and demand analysis stage,a business physical variable for realizing the business logic variable is established; and a demand function of the business physical variable is defined. In the accurate function demand design and demand analysis stage, combinations of function input parameter control contents and business physical variable control contents are established, change laws for business physical variable contents in combination groups are established, and output is performed.

Description

technical field [0001] The invention relates to the technical field of software development engineering, in particular to a method for generating a business variable-oriented software development scheme. Background technique [0002] Software development is a system engineering including requirements capture, requirements analysis, design, implementation and testing. At present, the most widely used software development tool on the market is the UML tool that adopts the object-oriented design method, but this tool has the following shortcomings: 1. It complicates the problem, that is, users and designers at the system level do not need to see things such as "class "With such a concept, users and designers do not need to care whether the system is implemented using a structure-oriented method or an object-oriented method.

Problems solved by technology

At present, the most widely used software development tool on the market is the UML tool that adopts the object-oriented design method, but this tool has the following shortcomings: 1. It complicates the problem, that is, users and designers at the system level do not need to see things such as "class "With such a concept, users and designers do not need to care whether the system is implemented using a structure-oriented method or an object-oriented method. If these factors are considered, it will undoubtedly complicate the requirements analysis; 2. Although modeling is emphasized, both There are still static diagrams and dynamic diagrams, but there is no clear statement about the extent to which the design and analysis of these diagrams should be done. What content needs to be "detailed"? What content needs to be "coarse"? The key problem has not been solved. Many practical engineering examples spend a lot of time drawing UML graphics, and these graphics bring very little value. In the final analysis, there is no accurate demand design and demand analysis; 3. If software development does not use Object-oriented methods, such as C language, it is very inappropriate to use UML tools for software function requirements design and requirements analysis, that is, the application of this development tool has limitations

[0003] In addition, most of the current software development methods cannot provide accurate test cases for each development stage, and even if the test cases are given, because there is no precise requirement design and requirement analysis in each stage, these test cases are often It will be abandoned after the coding is completed, because due to the large changes in the requirements design and requirements analysis at each stage, the test cases given above are no longer applicable, which causes a lot of waste of resources

It is also precisely because most of the current software development methods do not have accurate requirement design and requirement analysis, so functions cannot be outsourced during the code development stage, which will bring about long software development cycles and high management costs.
