在分析了常规统计报表结构的基础上,将计算机BASIC语言与数据库dBASE结合起来,编写了针对数据库的随机统计程序。该程序实现了用BASIC语言对键盘输入的条件表达式和代数表达式的分解运算,并采用设置虚拟层的方法,解决了统计结果中需要保留原始记录的问题,使该程序具有功能强,使用灵活、方便的特点。该程序既适用于资源报表的统计,也适用于生产计划报表的统计。 Based on the analysis of the structure of the conventional statistical report, the computer BASIC language is combined with the database dBASE to compile a random statistical program for the database. This program realizes the decomposition operation of conditional expression and algebraic expression input by keyboard in BASIC language and adopts the method of setting virtual layer to solve the problem that the original record needs to be kept in the statistical result so that the program has the advantages of strong function, Flexible, convenient features. This procedure applies to both the statistics of resource reports and the statistics of production plan reports.
