EDM and IDM only deal with documents, not databases. If you have a database with information you want, you'll have to export it to an excel spreadsheet, csv, or tab/space delimited file to be scanned with EDM.
IDM is for matching unstructured data so you wouldn't have those in a database, but rather in text files like Microsoft Word and PowerPoint, PDF files, design plans, source code, CAD/CAM images, financial
reports, mergers and acquisition documents, and many others.
Hope that clarifies
