我知道这个信息无处不在，但其如此巨大的难以选择合适的方法。所以即使指着我正确的地方也适用。储存大量的表格/模式
我开发的软件，他输入自己的股票交易客户端和它的各种数据输出到一个表。没有任何访问的股票数据，这是全部内部的，仅供个人使用。
我坚持的是什么，他希望能够通过周一洗牌至周五，或视图从一年前的输入数据。那么我将如何存储每日表格数据。
我应该表的模型保存到一个文件或数据库？也许有一种我不知道的方法。
的表是10列宽有大约900排很长，如果该事项对任何人。

要获得一个答案你需要提供你已经写的更多细节。征求意见将让他锁定。 –
是的，我之前有问题询问数据库问题。发布我的代码，尽管我真的是我的数据操作和表/模型/输入设置。我没有实现每日轮换，因为我不知道如何设置要保存的数据。 –
