I want to draw a DIKW Hierarchy diagram exactly as is in the picture below:

How can I do it with tikz?

Here are your labeled lines.

There are other ways to shift nodes but IMO the transform canvas is the most direct, so you are doing fine for that aspect.

To label a line, you can add a node command at the end of the line specification. The label may be placed above or below and you can specify where along the line with keywords such as midway or the more general pos=<fraction along line>. I also shifted the diagonal lines so that they may both be seen (since one was dashed).

I added a macro to simplify the shifting of the diagonal lines.

\documentclass[border=5pt]{standalone}

\usepackage{amsmath,amssymb}

\usepackage{tikz}
\usetikzlibrary{calc}


\begin{document}

\begin{tikzpicture}[node distance=2.8cm, auto]

\pgfmathsetmacro{\shift}{0.3ex}

\node (P) {$\mathfrak{P}=\bigoplus_{i\in I}\mathfrak{P_{i}}$};
\node(Q)[right of=P] {$\mathfrak{P_{j}}$};
\node (B) [below of=P] {$\mathfrak{B}$};
\node (C) [right of=B] {$\mathfrak{C}$};

\draw[transform canvas={yshift=0.5ex},->] (P) --(Q) node[above,midway] {\tiny top};
\draw[transform canvas={yshift=-0.5ex},->](Q) -- (P) node[below,midway] {\tiny bottom}; 
\draw[->](Q) to node {$a$}(C);
\draw[->] (P) to node[swap] {$\pi_{j}$} (B);
\draw[->,dashed] (B) to node {$\psi$} (C);

\draw[->,transform canvas={xshift=-\shift,yshift=\shift}](Q) to node {$a$}(B);
\draw[->, dashed,transform canvas={xshift=\shift,yshift=-\shift}] (Q) to node[swap] {$g$} (B);

\end{tikzpicture}

\end{document}

You can use draw,double=<color>,double distance = <dimen> in every node style.:

\documentclass{article}

\setlength{\parindent}{0mm}

\usepackage{paralist}
\usepackage{tikz}

\begin{document}
\begin{tikzpicture}[every node/.style = {shape          = rectangle,
                                         rounded corners,
                                         draw,                    %% here
                                         double=red,              %% here
                                         double distance =1pt,    %% here
                                         fill           = black!30!white,
                                         minimum width  = 3cm,
                                         minimum height = 1.5cm,
                                         align          = center,                                         
                                         text           = black},
                   black edge/.style  = { -,
                                         ultra thick,
                                         black,
                                         shorten >= 2pt}]

% the nodes : possible  \newcommand*\dx{5} \newcommand*\dy{2}
\node(0;0) at (5,0) {Patients};
  \node(1;1)  at (10, 2) {Treatment $A_1$};
  \node(1;-1) at (10,-2) {Treatment $A_2$};
\foreach \j in {-1,1}
  { \draw[black edge] (0;0.east) -- (1;\j.west); }
\end{tikzpicture}

\end{document}

If you don't want color, use simple double instead of double=<color>.
