I'm not exactly sure what it is you're asking about, but it sounds to me like you have a class that contains a SqlDataAdapter to access your database and you want to use that component in another system ... is that correct?

Your class that contains this component should be part of a project and you would compile it to a .DLL, not an .EXE. It's a simple matter then to just reference your .DLL in the other system ... assuming of course that your other system is a .NET app as well. If not, then you'll have to use COM and all that ... which I haven't done yet and others here will be able to provide you with better answers if you need them.
