# How to reproduce this image in LaTeX?

Can we reproduce this image in LaTeX? I have some idea using

\usepackage{tikz}
\usetikzlibrary{positioning,fit,shapes.geometric,backgrounds,matrix,calc,shapes}


but so far I can't achieve this, as I am new to LaTeX.

    \documentclass{standalone}
\usepackage{tikz}
\usetikzlibrary{matrix,calc,decorations.pathreplacing,shapes.misc}
\tikzset{
module/.style={draw, rectangle, fill=white, minimum size=1em,outer sep=0,inner sep=0},
mycross/.style={path picture={
\draw[#1] (path picture bounding box.south west) rectangle (path picture bounding box.north east);
\draw[#1] (path picture bounding box.south west) --  (path picture bounding box.north east);
\draw[#1] (path picture bounding box.south east) -- (path picture bounding box.north west);
}}
}
\begin{document}
\begin{tikzpicture}
\tikzset{column align/.style 2 args={column #1/.append style={nodes={execute at begin
node={\setbox\matrixcellbox=\hbox\bgroup},
execute at end
node={\egroup\eqmakebox[\tikzmatrixname\the\pgfmatrixcurrentcolumn][#2]{\copy\matrixcellbox}}}}}}
\matrix[fill=black!20, matrix of nodes, nodes={module,anchor=center},
row sep=-\pgflinewidth,column sep=-\pgflinewidth
]
{
Y & Y & Y \\
Y & Y & |[mycross]|  \\
Y & Y & Y \\
};
\end{tikzpicture}
\end{document}



Current result:

• Welcome. // Looks, like you're miles away. 2 suggestion: 1) Have a look into the short intro here and look up more details in the big manual: ctan.org/pkg/pgf . 3) Have a look into the tikz gallery, visit drawings and their code: texample.net/tikz/examples/feature/nodes-and-shapes (Don't be intimidated: it's easier in the end ...) . 3) Have a look to the right, at the links presented, centered around this question.

Don't need any of those library. Start from simple node path.

\documentclass{standalone}
\usepackage{tikz}
\tikzset{
mynode/.style args={#1/#2/#3/#4/#5}{
#1,
fill=#2,
rounded corners=#5,
minimum height=#3,
minimum width=#4,
font=\sffamily\Large,
},
}
\begin{document}
\begin{tikzpicture}
\node (a) [mynode=/gray!15/3cm/18cm/10pt] {};
\node (b) [mynode={white,right=1cm}/blue/2cm/5.5cm/0pt] at (a.west) {Data File};
\coordinate (tmp) at (b.east);
\foreach \word/\col in {Parameter\\file/green,Control\\ File/green!50!black,Password\\File/blue!30,Archive Log\\File/purple}
\node (tmp) [mynode={white,anchor=west,right=3pt,align=center}/\col/2cm/2.5cm/0pt] at (tmp.east) {\word};
\end{tikzpicture}
\end{document}


• i really wonder can we write a nested loop? how can I go for that memory part. Jun 20 at 11:30
• @CADENTIC Loop for different size and location nodes is kind of hard, you could draw them individually.
