"深入理解用UML进行面向对象的分析和设计：模块10描述分发活动"。

Mastering Object-Oriented Analysis and Design with UML, Module 10, focuses on the topic of Distribution in software systems. The objective of this module is to provide an understanding of how the functionality of a system can be distributed across physical nodes. This is a crucial aspect of system architecture that needs to be addressed during the design phase of software development. The Describe Distribution activity is performed to explain the purpose of distributing system functionality and to determine when in the software development lifecycle this activity should be conducted. By understanding how the system's functionality can be distributed across physical nodes, developers can effectively model the distribution decisions in the Deployment Model. In order to effectively describe distribution, developers must articulate the rationale and considerations that support the architectural decisions. This involves analyzing the system's requirements, identifying the components that need to be distributed, and determining how they will interact with each other across different nodes. By modeling the distribution decisions in the Deployment Model, developers can ensure that the system is designed to meet the performance, scalability, and reliability requirements of the end users. Overall, mastering the concepts of distribution in software systems is essential for creating well-designed and efficient systems. By applying the principles of Object-Oriented Analysis and Design with UML, developers can effectively model and implement the distribution of system functionality to ensure the success of their software projects.
