Nice of you to recognize that you (and nearly everybody else) is blowing hot steam.
There is no college in Germany. Until very recently, we didn't even have Bachelor degrees at all. There are full universities and "universities of applied science". (Fachhochschulen). The latter are, in theory, not staffed and equipped for research and cater to a lower qualified student tier, but these days everyone and his dog are offering masters programs under the new Bologna rules, and depending on their motivation and other factors they may or may not do research.
I do assume the OP has the necessary requirements for university attendance (Abitur for universities, "Fachhochschulreife" plus relevant experience for universities of applied science).
The MBA market in Germany has become especially intransparent. Here Bologna has really ruined the educational system. Crappy provincial Fachhochschulen compete with first rate universities offering the same title. Moreover, the MBA is NOT part of the "consecutive" system (where a Master require a Bachelor) but are basically given to everyone who completed the course, whatever its requirements were. There are MBAs that can be had after 2 years of distance learning.
If you want a regular masters degree in Business Administration, otoh, you'll get a M.A. in Business administration. Bologna at its finest.
