UML的目标之一就是为开发团队提供标准通用的设计语言来开发和构建计算机应用。UML提出了一套IT专业人员期待多年的统一的标准建模符号。通过使用UML，这些人员能够阅读和交流系统架构和设计规划--就像建筑工人多年来所使用的建筑设计图一样。-One of the goals of the UML is the standard common language for the development team to develop and build computer applications.UML has proposed a set of IT professionals look forward to years of a unified standard modeling notation. Using UML, these personnel be able to read and communication system architecture and design and planning- like the building design has been used over the years by the construction workers.
