简介:可扩展的标注语言(XML)为在基于万维网的应用代表并且互换数据成为了事实上的标准。并且XML看法,为指定用户的一扇虚拟窗户,广泛地被使用了。在实际系统,当他们需要通过看法更新来源数据时,用户们遇到所谓的看法更改问题。很长时间,看法更改问题是在数据库社区的一个待研究的问题。与各种各样的数据模型的开发,相应看法更改问题广泛地被研究了。在这篇论文,我们介绍看法更改问题的概念。我们调查并且比较以前的途径。特别,我们强调语义的角色。在XML上下文集中于这个问题,我们给讨论并且建议一个框架,它在看法定义时间收集语义信息。为实现这个框架的一些相关技术进一步被介绍。
简介:我们描述在模糊集合和代数学的亢奋的结构之间的关系。事实上,这篇论文是Davvaz介绍在的想法的继续(模糊集合Syst,117:477-484,2001)并且Bhakat和Das在(模糊集合Syst,80:359-368,1996)。有一个珍视间隔的模糊集合的模糊间隔价值的伪巧合的概念被介绍,这是在模糊集合的一个模糊的点的伪巧合的自然归纳。由使用这个新想法,这个概念珍视间隔(α,β)一个亢奋的模块的模糊sub-hypermodules被定义。这最新定义珍视间隔(α,模糊sub-hypermodule是的β)平常的模糊sub-hypermodule的归纳。我们将学习如此的模糊sub-hypermodules并且考虑一个亢奋的模块的基于含意的珍视间隔的模糊sub-hypermodules。
