基于元数据的通用表单动态生成技术

摘要

在信息系统领域中利用元数据自动生成通用表单的技术，不仅能提高软件的开发效率，降低软件运行的出错率，而且大大提高了软件的复用率。研究基于Delphi集成开发环境，通过不依赖数据库环境的DATASET控件，将数据库中的数据暂时存储在DATASET中，然后通过统一接口可将异构数据库的库表中内容按照一定规则显示在动态生成的表单上进行数据展示和维护。%In the field of information system , the technology using automatic metadata to generate general form , not only can im-prove the software development efficiency , reduce the error rate of running software , the software reuse ratio is increased also .By researching of Delphi integrated development environment , based on the database environment , does not rely on the DATASET control , the data in the database is temporarily stored in the DATASET , and then through a unified interface to heterogeneous da-tabase table of contents according to certain rules of display data display and maintenance in dynamically generated form .
