We construct an associative algebra with a decomposition into the direct sum of the underlying vector spaces of another associative algebra and its dual space such that both of them are subalgebras and the natural symmetric bilinear form is invariant or the natural antisymmetric bilinear form is a Connes cocycle. The former is called a double construction of Frobenius algebra and the latter is called a double construction of Connes cocycle which is interpreted in terms of dendriform algebras. Both of them are equivalent to a kind of bialgebras, namely, antisymmetric infinitesimal bialgebras and dendriform D-bialgebras respectively. In the coboundary cases, our study leads to what we call associative Yang-Baxter equation in an associative algebra and $D$-equation in a dendriform algebra respectively, which are analogues of the classical Yang-Baxter equation in a Lie algebra. We show that an antisymmetric solution of associative Yang-Baxter equation corresponds to the antisymmetric part of a certain operator called ${\mathcal O}$-operator which gives a double construction of Frobenius algebra, whereas a symmetric solution of $D$-equation corresponds to the symmetric part of an ${\mathcal O}$-operator which gives a double construction of Connes cocycle. By comparing antisymmetric infinitesimal bialgebras and dendriform D-bialgebras, we observe that there is a clear analogy between them. Due to the correspondences between certain symmetries and antisymmetries appearing in the analogy, we regard it as a kind of duality.
