This article shares with you the content of a sample analysis of UML requirements analysis. The editor thinks it is very practical, so share it with you as a reference and follow the editor to have a look.

Modeling tool UML requirement analysis

In the history of software engineering, requirement analysis has been regarded as the simplest step in the whole software engineering for a long time, but in the past decade, more and more people have realized that it is the most critical process in the whole process. If the analysts do not correctly recognize the customer's needs in the requirements analysis, then the software can not actually meet the customer's requirements, or lead to frequent changes in requirements, and the software can not be completed within the specified time.

In the UML requirements analysis stage, the system objectives and functions determined by the feasibility analysis should be further discussed in detail to determine the system "what to do?" Finally, the logical model of the target system is established.

The first is to obtain the physical model of the current system. The physical model is a true portrayal of the current system, which may be a process operated manually, or an existing computer system that needs to be improved. First of all, it is necessary to analyze and understand the current system, understand its organization, data flow, input and output, and resource utilization, and draw its physical model on the basis of analysis. Then abstract the logical model of the current system.

Based on the physical model, the logical model removes some secondary factors and establishes a logical model that reflects the essence of the system. Next, the logical model of the target system is established. By analyzing the logical difference between the target system and the current system, the logical model of the target system that meets the needs of users is established. * complements the logical model of the target system. Supplement and improve the target system, adding some secondary factors, such as error handling and so on.

UML (TheUnifiedModelingLanguage, Unified Modeling language) is a standardized language for compiling system blueprints, which can build visual system models for complex systems. It has been accepted by the industrial standardization organization OMG (ObjectManagementGroup), and has been supported by many famous computer manufacturers such as Microsoft, HP, IBM, Oracle, etc., and is gradually being applied to the process of requirement analysis.
