如果没有可用的导出选项，如何在旧版DOS应用程序中导出数据？ [英] How can I export data in a legacy DOS application when no export option is available?

问题描述

我们的客户的任务是使用RAIMA数据库 从旧版DOS系统导出数据，因此可以将其导入我们为其编写的新系统。它看起来像数据存储在平面文件格式，虽然当我们打开文件的大多数文本是乱码。

我们看到Raima数据库管理器位于我们打开的文件的顶部...我们尝试使用Googling这个术语，似乎它是一个旧的数据库格式。不用说，编写软件的供应商不再支持它。有没有其他方法，我们可以得到这些数据导出？

有自动从屏幕上删除数据的方法吗？

注意

这是一个简单的发票系统，所有信息都显示在应用程序的单个屏幕上。

解决方案

We've been given the task by my customer to export data from a legacy DOS system, using a RAIMA database, so it can be imported into a new system we are writing for them. It looks like the data is stored in a flat file format, though when we open the files most of the text is gibberish.

We do see Raima Database Manager along the top of the files we opened ... We tried Googling that term and seems it is an old database format. Needless to say the vendor who wrote the software no longer supports it. Is there any other way we can get this data to export?

Is there a way to automatically scrape the data from the screen?

Note

It's a simple invoicing system, all the information is on a single screen in the application.

for Raima Data Manager Version 3.21A This article indicates that the app was likely written in C and it used Raima Data Definition Language to structure the files - look in the files for something similar check the .dbd and .tbl - you may have to view them with something like VI that has a hex mode. It is very likely the data structures are embeded in one of the files.
