摘要
数据库管理一般要符合范式的要求,但在数据范式下的数据一般不能直接打印输出,都需要进行必要的转换,而转换生成交叉表更是最常用与最实用的方法。在Java与Oracle的环境下,探讨了交叉表的生成过程与多表联合生成动态交叉表的方法。
The management of database should generally conform to the normal form, however, the data in this form can not be printed directly and need to be transformed into another form. The creation of crosstab through transformation is the practical method most frequently used. The creation process of the crosstab and the method of creating dynamic crosstab with poly form are discussed in this paper under the platform of Java or Oracle.
