Usually it is basic table maintenance that doesn t have a major impact on the application , so it doesn t appear to add a lot of value to the actor and is not often considered a primary use case 通常,基本的表维护对应用程序并不具有主要的影响,所以它好象不能给操作者带来多大的价值,经常不被看作是主要的用例。
Combined with the properties and demand of data for biochemical analysis , such as patient sample data , quality control data and item method data , this dissertation discusses the designing of basic tables and query tables of the database , the establishment of the relations among tables , and the methods to store , query and update the database 文中结合生化分析的病人样品数据、质控样品数据、项目测试方法数据的特点和要求,详细分析了数据库基本表和查询表的设计,表之间关系的建立,数据库的写入、查询和更新的方法。
At last , this paper summarizes the method of component development . in order to make general components be generally used in mis field , the concept of basic table and alias are imported into the design process . the prototype of general components makes it possible that different mis could share some data 为了解决构件的通用性问题,本文在构件的设计中引入了“基本表”和“别名”的想法,从而使不同的管理信息系统能够共享某些数据;本文充分利用了active控件的包容特性,把繁复的数据库操作封装在一个部件中,从而减轻了开发人员的劳动强度;本文还在通用构件中实现了分布式工作的能力,扩展了传统的管理信息系统的工作模式。
