This language implements the syntax definition , such as report data source sql operations between data and report conditions etc . the report data files can be gotten after the data parser parses the report data definition file with dom 本文重点描述了基于xml的自定义报表数据语言xrdl ,该语言实现了报表数据源sql 、数据间的运算、报表条件、合计等语法定义。
( 2 ) in order to validate the efficiency of algorithm , this paper design and implement a testing , platform rule processor based on sql server . the main function of the processor is to translate the first order logic rule into embedded - sql programs , which make sql server dbms possess the capability in expressing recursive query with logic language ( 2 )为验证算法的有效性,该文设计实现了一个测试平台? ?基于sqlserver的规则处理器,其主要功能为自动把一阶逻辑规则转换为含有sql语句的过程代码,这使得sqlserver数据库管理系统有了用逻辑数据语言表示递归查询的能力。
