Is it possible to create the following flowchart in Latex?

Can you provide an code example?Thanks in advance.

A starting point using TikZ and its positioning library:

The code:
\documentclass{article}
\usepackage{tikz}
\usetikzlibrary{positioning}
\begin{document}
\begin{tikzpicture}[
mynode/.style={
draw,
rounded corners,
font=\sffamily,
text width=1.5cm,
align=center
},
ar/.style={
->,
>=latex,
}
]
\node[mynode] (c1) {data};
\node[mynode,below=of c1] (c2) {data};
\node[mynode,below=of c2] (c3) {data};
\node[mynode,below=of c3] (c4) {data};
\coordinate[below=20pt of c4] (aux);
\node[mynode,left=of c2] (l1) {data};
\node[mynode,below=of l1] (l2) {data};
\node[mynode,right=of c2] (r1) {data};
\node[mynode,right=of r1] (rr1) {data};
\foreach \Valor in {1,2,3}
{
\draw[ar] (c\Valor) -- (c\the\numexpr\Valor+1\relax);
}
\draw[ar] (c4.south) -- ++(0,-8pt) -| ([xshift=-6pt]r1.south);
\draw[ar] ([xshift=-6pt]c1.south) -- ++(0,-15pt) -| (l1);
\draw[ar] ([xshift=6pt]c1.south) -- ++(0,-15pt) -| (r1);
\draw[ar] ([xshift=6pt]l1.south) -- ([xshift=6pt]l1.south|-l2.north);
\draw[ar]
([xshift=-6pt]l1.south) --
++(0,-15pt) --
++(-25pt,0) |-
(aux) -|
([xshift=6pt]r1.south);
\draw[ar] (r1) -- (rr1);
\end{tikzpicture}
\end{document}
\documentclass{}...\begin{document}etc. You can improve your question by adding a minimal working example (MWE) that more users can copy/paste onto their systems to work on. – cfr Nov 11 '14 at 18:17
