看了以上的需求,想起客户的话,这个很简单,哒哒哒哒哒.....最后给了句,你看看三天能完成吗? 我们看了三天,还没看出咋完成,哈哈... 你的需求如果是具体的特定的数据库,倒是好办,但是要通用的解决方案就麻烦了。 1、2、3基本都可以,不过1、2要修改为5

看了以上的需求,想起客户的话,这个很简单,哒哒哒哒哒.....最后给了句,你看看三天能完成吗?

我们看了三天,还没看出咋完成,哈哈...

你的需求如果是具体的特定的数据库,倒是好办,但是要通用的解决方案就麻烦了。

1、2、3基本都可以,不过1、2要修改为50条数据或是100条数据一保存,全部保存不现实,一条条保存太慢。

要考虑到参照完整性的话,数据导入一定要有特定的顺序。主表先导,再到子表。

不管你是保存为XML、EXCEL还是Sqlite还是Access或是MDF,这个都不重要,关键还是导入导出的代码。

感觉这种事情不会经常进行啊,哪家公司无聊了整天这么折腾数据啊,一年搞个一次差不多了。
