- 共有约70个业务.
- 这些业务中约有8个公共字段
- 每个业务除公共字段外还有5-20个与其他业务不同的字段
- 比如 业务 1 有字段如下 公共字段(渠道, 大小..) 自有字段 : 姓名, 身份证, 性别.. 业务 2 有字段如下 公共字段(渠道, 大小..) 自由字段 : 颜色, 长度, 宽度...
- 目前的解决方案是一个业务放到一张表中, 只统计了五个业务, 使用了五张表 但随着业务量增多表的数量也将增多到70个
- 使用mongodb这种nosql的数据库可否 ? 前辈说Nosql只适合简单数据模型的数据
- 或者hadoop等..?PS. 每天各种业务加起来的数据量约5万条.
