問題描述
我正在開發一個 GPS 計算器，它使用大量數據來計算不同的值，例如 RMSE(均方根誤差)和 NSSDA(空間數據的國家標準).數據來自各種不同型號的 GPS 單元，差異很大，即內部/外部天線；自動、WAAS、DGPS、PPS 信號；開放式、輕型、中型、重型機蓋；等等.基本上需要存儲大量數據來計算各種各樣的期望結果.
I am developing a GPS calculator that uses a lot of data to calculate different values, such as RMSE (root mean square error) and NSSDA (national standard for spatial data). The data is from a variety of different models of GPS units with a great degree in variation, i.e. internal/external antennae; auto, WAAS, DGPS, PPS signal; open, light, medium, heavy canopy; etc. Basically a whole lot of data needs to be stored to compute the huge variety of desired outcomes.
數據將始終被讀取，只有在極少數情況下才會添加新數據.如果確實需要添加，則很可能是其中一位開發人員，而不是該程序的用戶.因此，我們對使用 SQLite 非常感興趣.我們的服務器上有 Oracle，但任何表的創建都必須由上級完成，有時可能需要數周時間.出于這個原因，SQLite 似乎對我們有用.我從未使用過 SQLite，所以我想知道它是否是正確的選擇.但是，大多數關于 SQLite 和 Flex 的文檔似乎都與作為本地數據庫的 AIR 應用程序和 SQLite 有關.服務器上的 SQLite 文件與執行所需計算的 flex 應用程序甚至可以工作嗎?還是我在使用 SQLite 文件方面做得不夠好?
The data will always be read, and only in rare conditions will new data be added. If it does need to be added, it will most likely be by one of the developers, not users of the program. Because of this, we are very interested in using SQLite. We have Oracle on our server, but any creation of tables must be done by higher-ups, which can sometimes take weeks. For this reason SQLite seems like it might work for us. I have never used SQLite, so I am wondering if it is the right choice. However, most documentation about SQLite and Flex seems to be pertaining to AIR applications and SQLite as a local database. Would having an SQLite file on the server with a flex application performing the desired calculations even work? Or am I way off the mark on the use of SQLite files?
推薦答案
我喜歡 sqlLITE，但我只將它與 Perl 一起使用.
I love sqlLITE but I have only used it with Perl.
您可以使用 Amazon 的 SimpleDB 之類的東西，它是一個可以作為網絡服務訪問的數據庫.如果您的數據少于 1GB，并且每月使用時間少于 25 小時，它也是免費的.
You could use something like Amazon's SimpleDB which is a database that can be accessed as a webService. It's also free if you have less than 1GB of data and use it less than 25 hours a month.
鏈接到 simpleDBhttp://aws.amazon.com/simpledb/
Link to simpleDB http://aws.amazon.com/simpledb/
有一個用于 simpleDB 的 AS3 庫，但我沒有擁有多個鏈接的聲譽:-(.. 所以谷歌:亞馬遜圖解生活 simpleDB"
There is an AS3 library for simpleDB but I don't have the reputation to have more than one link :-(.. So google: "Amazon illustratedlife simpleDB"
祝你好運
