也许我可以帮助你，因为 2 年前我已经完成了你现在正在做的事情。
我必须设计一个 MySQL 数据仓库，包括 ETL 系统，完全基于在 Linux 上运行的 RM COBOL ERP 应用程序的文件。
该应用程序有 600 多个文件，目前尚不清楚其中有多少最终会进入数据库。大多数重要文件都在 COMP 字段上进行了索引，以使其更难，其中一个明显的要求是文件及其索引键之间的所有关系都可以在数据库上重现。所以我可能需要每个文件的每个字段。
考虑到文件的数量，手动一个一个地处理所有文件是没有问题的。
我只看到了一个实用的解决方案：应用automatic programming。即编写一个可以生成程序的程序，仅来自一个来源：cobol 抄写本。
我对允许使用的技术有一些限制（由客户设置）。我最终得到了一个 VB.NET 应用程序，该应用程序将 COBOL 字帖作为输入，并且：
- 生成 COBOL 程序，通过读取原始索引文件并将记录写入顺序文本文件，将数据转换为可利用的东西。
- 使用将这些数据文件从 MS Access 导入 MySQL 所需的所有代码生成 VBA 模块（包括 CREATE TABLE 和索引）
在项目开始时，我遇到了与现在完全相同的问题，尤其是那些该死的 REDEFINES。我发现列出和编码所有抄写本可能性的任务，如果不是不可能的话，至少是危险的。
所以我研究了另一种方式，发现了这个：
CB2XML
COBOL copybook 到 XML 转换器：SourceForge
这为我节省了数周的字帖解析和解释工作。
它可以解析 COBOL 字帖，将它们变成一个 XML 文件，完美地描述所有具有许多有用属性的 PICTURE，例如 length 或 type。它完全支持 COBOL'86 标准。

所有 XML 属性的列表
这里懒得复制粘贴我的VB.NET代码了，有注释清楚地解释了每个属性
For Each Attribute As Xml.XmlAttribute In itemNode.Attributes
Select Case Attribute.Name
Case "name" ' FIeld name
Case "level" ' PICTURE level
Case "numeric" ' True if numeric data type
Case "picture" ' COmplete PICTURE string
Case "storage-length" ' Variable storage lenght
Case "usage" ' If COMP field, give the original COMP type ("computational-x")
Case "signed" ' true if PIC S...
Case "scale" ' Give number of digits afeter decimal point
Case "redefined" ' true if the field is redifined afterwards
Case "redefines" ' If REDEFINES : give the name of the redefined field
Case "occurs" ' give the number of occurences if it's an ARRAY
Case "position" ' Give the line position in the original copybook
Case "display-length" ' Give the display size
Case "filename" ' Give the FD name
在这种 XML 结构的帮助下，我已经实现了所有目标，甚至更多。
生成的 COBOL 程序将 索引文件（只能使用 RM cobol 运行时读取）转换为 平面文件，处理每个字段，包括 ARRAYS 和 REDEFINES。
- 对于 REDEFINES：我为“主要”图片及其所有 REDEFINES 更改创建一个字段，并且它们的类型与其 COBOL PICTURE 匹配
- 对于 ARRAY，我为每个元素创建了一个字段，并且还创建了一个包含整个数组“行”的巨大字段
- 对于 COMPUTATIONAL 字段，我只是将原始 COMP 移动到完全相同的 DISPLAY PICTURE 中
并非所有字段在数据库中都有用途，但至少所有内容始终可用
有了上面的发票文件，SEQUENTIAL 文本文件字帖就变成了这样：

我在生成的 VBA 模块中有更多内容，生成的 xml 的详细程度和准确性对所有这些模块都有很大帮助：
- 我创建了一个类来管理字段的所有方面，特别是按照原始 PICTURE 和 VBA 类型（日期、长整数、双精度数、货币等）处理 VBA/MySQL 的转换，并且有一个钩子以防您想强制使用其他类型。
- 它完全处理元数据的创建（也在 MySQL 中）
- 它处理导入数据时的错误，在文件和字段级别记录所有内容
我可能已经展示了足够多的东西来给你一些想法，所以我会停在那里。
最重要的是：当我们将 COBOL ERP 中进行的复杂计算转换为针对新数据仓库运行的 SQL 语句时，DB 返回的数字与 ERP 中返回的数字完全相同。在数百万条记录中，计算上没有一位数的损失。这是证明它有效的最好方法:-)
如果您想知道为什么我使用 Access/VBA 而不是 .NET 进行导入：这是一个不可协商的要求。
最后一点：我与 CB2XML 没有任何关系，这不是它的广告。这只是一个很棒且有用的软件，值得关注。
