They are enharmonice equivalents!. It depend upon which way you are going on the circle of fifths!. The names of the notes change depending upon what scale or key you are playing!. "Dog as Star" is right, you will more likely see a piece in Db that C#!. Db is a perfect fourth from Ab!. If you were to start Bb, Eb, Ab, Db!. C# is a perfect fifth from F#!. If you were to start F#, to C#!. This is the order in which the sharps or flats would appear in the key signature!. So in the key of D, there is an F# and a C# in the key signature!. In the key of Ab there is Bb, Eb, Ab, and Db!. Db and C# are enharmonic equivalents, but in this case are part of entirely different scales or key centers!. Www@QuestionHome@Com

yep, you got it right!. they're basically the same scale, but for your example, Db has 5 flats while C# has 7 sharps!. if you play Db and C# on the piano, you'll notice that they're actually the same note, which is called enharmonic notes!. however, you won't see a piece in the key of C# nearly as much as its enharmonic key, Db!.
