我也许可以帮助你,因为2年前我已经完成了你现在正在做什么。
我要设计一个MySQL数据仓库,包括ETL系统,专门从Linux上运行的RM COBOL ERP应用文件为主。 该应用程序已超过600个文件,但仍不清楚有多少人最终会在数据库中结束。 最重要的文件进行索引,对COMP领域使其更难,和明显的要求之一是,文件和它们的索引键之间的所有关系可以在数据库上进行复制。 所以,我可能用到的每一个文件的各个领域。
给文件的数量,这是毫无疑问的对待所有的文件,手动和一个接一个。
所以我的想法是代码采取输入和COBOL习字一个VB.NET应用程序:
- 生成的数据转换成可利用的东西,通过读取原始索引的文件,并在连续的文本文件写入记录COBOL程序。
- 生成与从MS访问这些数据文件导入到MySQL所需的所有代码(包括CREATE TABLE和索引)VBA模块
在项目的开始,我现在遇到了正好比你同样的问题,特别是那些该死的REDEFINES。 我发现,上市和编码都字帖的可能性,如果不是不可能的,至少危险的任务。 所以,我看着另一种方式,并发现这一点:
CB2XML
COBOL字帖到XML转换器 : SourceForge上
这救了我的辛勤工作周的字帖解析和口译。 它可以解析COBOL习字将它们转变成完全描述了很多有用的属性,如长度或类型的所有画面中的XML文件。 它完全支持COBOL'86标准。
例如:

有了这个XML结构的帮助下我已经实现了所有的目标和超越。
该索引文件 (仅适用于RM COBOL运行时可读)转换成平面文件涉及各个领域,阵列和生成的COBOL程序重新定义包括在内。
- 对于REDEFINES:我创建了两个“主” PICTURE一个领域,它的REDEFINES改建和它们的类型及其COBOL PICTURE匹配
- 对于数组,我创建一个字段的每个元素,并且还包含整个阵列“线”一个巨大的场
- 为了计算领域,我只需将原来的COMP到完全相同的显示图片
并非所有的领域都有着目的时,他们在数据库中,但至少一切是所有可用的时间
通过上面的文件,顺序文本文件字帖变成这样:

我在生成的VBA模块得多,并且生成的XML的细节和准确性的水平帮助了很多为所有这些:
- 我创建了管理领域的方方面面类,并特别采取以下原始图片和VBA类型(日期,长,双打,货币等)的转换VBA / MySQL的照顾,有一个钩的情况下,你要强制另一种类型。
- 它与元数据创建完全交易(也MySQL中)
- 它导入数据时,记录在文件和字段级别的一切与处理错误
我可能已经显示出足够的给你一些想法,所以我会停在那里。
最重要的是:在几十万条记录,我还没有计算一个数字的损失。 当我SUM()对数据库使用SQL的所有行,我有相同的数字比返回由原始的COBOL应用程序
如果你想知道为什么我用接入/ VBA,而不是.NET的输入:这是一个不可争辩的前提-_-
在最后一个音符:我不是在与CB2XML附属不管怎样,这不是它的广告。 这是一个巨大的和有益的软件,值得爱和关注。
REDEFINES
将会使你的任务更加艰巨。 这不是“编译器”知道使用哪些特定领域,直观,它是在现有的COBOL系统的代码,知道使用哪些字段。 会有一些指示,在另一个字段中的一些的值,这将表明在该特定的时间使用哪个字段。
以你的第二个例子,作为第一个是没有上下文的:
05 ADDRESS-PO-BOX-FLAG PIC X.
在使用数据之前字段将被询问。 直接(你可以找到很多可怕的代码在那里),或用88级的条件名称:
88 ADDRESS-IS-A-PO-BOX VALUE "Y". (an example only)
IF ADDRESS-IS-A-PO-BOX
some code relating to PO Boxes
ELSE
some code relating to other types of addresses
END-IF
你的第一个例子将用类似的方式来处理。
这是一个“老式”的使用重新定义,使用上相互排斥的情况下,记录相同的存储位置。 节省了存储,这是昂贵的。 您正在使用的系统是不是“老”,或者它的设计是由虚假的“经验”感染。
你有两个选择广泛:复制数据的所有条件选择(让你有两套业务逻辑的步骤,以保持); 得到更改的文件,使每个领域占有自己的存储。
COMP-3的存在下(或填充DECIMAL)或COMP / COMP-4 / COMP-5 / BINARY数据类型也为你复杂的事情。 你需要做的,然后你EBCDIC到ASCII在外地一级,实际EBCDIC数据,做任何有必要转换或简单地获得“计算”的数据。
另外要注意,(开头以S,但没有一个明确的“计算”的使用与图片数字字段)显然将包含在最后一个字节“字符”数据的签署,显示数字领域,为标志保持为“ overpunch”最后一个字节的。
需要注意的是二进制数据类型将是大端。
如果您收到这没有REDEFINES,没有“计算”领域,并没有迹象嵌入(或隐含的小数位)文件它会为你大量简单。 所有的数据都将是字符,你可以在记录级EBCDIC到ASCII(或在文件级别,用你的文件传输机制)。
如果你看一下问题在这里标记COMP-3,你会发现这进一步讨论,如果你决定荒谬的路线(您的程序了解本地主机COBOL数据项,而不是简单的“文本”)是唯一可行的方法去的话,也有在讨论一些事情可能对你有用,并能使用或应用。
如果你的公司是“调控”外,然后确保您的合规性,审计和会计部门很高兴与你的设计,你一行代码前。 哎呦。 晚了。 让我们希望它是制造。
