I am recently working with Adabas. Also we have a database on oracle. We need to receive data from both databases and process them together. Please, suggest me how do it?

I know this is an old request, but if anybody is still interested, we do this by writing the Oracle data to a flat file with a predefined field-separated structure.
Then the file is copied to the mainfraime where it is read by a Natural program and broken up into the relevant Adabas tables/fields.
