database file formats info requested

I am posting this for a co-worker that does not have net access. You may respond to me or him.

	Hi,
	I am interested in finding information on the 
	file formats in Informix, Progress, and Oracle.
	Are there utilities out there that will read
	the database files for these databases.
	We are trying to tie the data together from several
	different sources and would like to create a central
	utility.
	We have had trouble using anyone of these sources.
	The Progress utilities require that you precompile
	and hard code the name of the files that you wish	
	to modify. It is ignorant of Informix data files
	as well. Informix and Oracle have their problems
	as well.
	I would like share ware or lists of vendor software
	either or both are fine.
	If the file formats are documented in good texts 
	that information would be most welcome.

	Thank You for any assistance.

	don fair.
