我知道這個信息無處不在，但其如此巨大的難以選擇合適的方法。所以即使指着我正確的地方也適用。儲存大量的表格/模式
我開發的軟件，他輸入自己的股票交易客戶端和它的各種數據輸出到一個表。沒有任何訪問的股票數據，這是全部內部的，僅供個人使用。
我堅持的是什麼，他希望能夠通過週一洗牌至週五，或視圖從一年前的輸入數據。那麼我將如何存儲每日表格數據。
我應該表的模型保存到一個文件或數據庫？也許有一種我不知道的方法。
的表是10列寬有大約900排很長，如果該事項對任何人。

解答這裏更多的代碼的要求是什麼，我已經打破down.`

要獲得一個答案你需要提供你已經寫的更多細節。徵求意見將讓他鎖定。 –
是的，我之前有問題詢問數據庫問題。發佈我的代碼，儘管我真的是我的數據操作和表/模型/輸入設置。我沒有實現每日輪換，因爲我不知道如何設置要保存的數據。 –
