So if you were to trivialize the task ahead, it could be summarized as follows: Replace file access calls by an SQL interface that would access information in a DB2 database instead of a flat file.

因此，我们要完成的任务是：用SQL访问替代文件访问调用，从而访问DB2数据库(而不是平面文件)中的信息。

The flows include transformations of business objects used by the flat file interface FlatFileImport1 and the claim check service interface ClaimCheckIntf.

请求流包括平面文件接口flatfileimport1和凭证索取服务接口ClaimCheckIntf使用的业务对象的转换。
