Note also that this radically increases the storage and computation overheads associated with aggregating all the data : every single statement turns into three statements , and every query on a predicate must go through a layer of indirection 另注：这主要增加了与聚集所有数据相关的存储量和计算开销：每条语句都变成三条语句，对谓语的每次查询都必须经过间接层。
As a result , he says the database will be checked to see if there is information on it that should not be there , policies and procedures related to the data will be reviewed and all staff members who deal with the information will undergo refresher training on how to handle it 最后,他表示,数据库将被彻查以确保无价值的信息不会被继续保留.与数据相关的政策和手续将会被重新检查,所有处理这些信息的工作人员将重新接受训练,以确保他们能处理好这些资料。
In first part , the main function and characteristics of chemstation are introduces in details . in the second part , the method of the object - oriented , the features of uml and rose served as the visual development environment of uml are summarized . in the last part , some standards and criteria of chromatography data are mentioned , such as unified chromatography data style technology and glp ( good laboratory practice for nonclinical laboratory studies ) 从总体结构上分为五大部分，这几个部分的主要内容有：在第一章中，简述了色谱数据处理软件和它的应用范围，然后简要的说明了选题背景和意义在第二章中，首先以色谱工作站n2000为例，介绍了色谱工作站的主要功能和特点；然后概括了面向对象的方法和uml统一建模语言以及可视化开发环境rose的特征；最后介绍了与色谱数据相关的标准和规范，如统一的分析数据和质量信息标准和glp (非临床优良实验研究规范) 。
In the three - dimensional modeling environment of mdt , the author makes the three - dimensional model which refer to the full - size data of all the part and assembling body , acquires the engineering drawing according with gb , manages the size data through database and outputs the data file which drives the model to produce all sort of parts and engineering drawing rapidly 基于mdt三维建模环境，建立起所有零部件及装配件的全尺寸数据相关的三维模型、及其符合国家标准的工程图。通过数据库管理尺寸数据，生成数据文件，从而驱动模型，快速生成各种需要的零部件及其工程图。
