In this paper we introduce a~new class of differential graded algebras named DG $\rho $-algebras and present Lie operations on this kind of algebras. We give two examples: the algebra of forms and the algebra of noncommutative differential forms of a~$\rho $-algebra. Then we introduce linear connections on a~$\rho $-bimodule $M$ over a~$\rho $-algebra~$A$ and extend these connections to the space of forms from $A$ to $M$. We apply these notions to the quantum hyperplane.
