试题解析

解析：在UML出来之前，没有一个主流建模语言。用户必须在很多类似的，在整个表达能力上区别不大的建模语言中进行选择。大多数建模语言共享了一组被大众接受的概念，这些概念在不同的语言中只有细微的区别。这种缺乏一致性的现象，阻止新的用户进入　OO领域和进行OO建模，从而无法发挥建模的威力。用户渴望采用一个(或不多的几个)受广大支持的建模语言，适合于通用用途。因为要支持很多类似的，但有细小区别的建模语言，所以一些开发商不愿意进入OO建模领域。特别是add-on工具的供应在萎缩，因为小开发商负担不起支持很多的来自不同的前端建模语言的不同格式。广泛鼓励底层工具和开发商，以及能满足特殊群体需要的小批量产品，对进入00工业是非常重要的。
