“面向对象”的建模语言出现在20世纪 70年代中期至80年代后期之间,那时方法论的学者们面对面向对象编程语言的新风格和日趋复杂的应用,开始用分析与设计的新方法进行实践。在1989到1994年间,“面向对象”的方法从不足10种增加到50种以上。面对这么多的方法,很多用户很难找到一种完全满足他们要求的建模语言,于是就加剧了所谓的方法战争。通 “Object-oriented” modeling languages ​​emerged between the mid-1970s and the late 1980s when methodological scholars faced a new style of object-oriented programming language and increasingly sophisticated applications, beginning with a new approach to analysis and design Practice. Between 1989 and 1994, the number of “object-oriented” approaches increased from less than 10 to more than 50. Faced with so many methods, many users find it hard to find a modeling language that fully meets their requirements, thus aggravating the so-called method war. through
