TikZ-PGF Graphics – How to Create a Frame for tikzpicture

graphicstikz-pgf

I have a figure structured as:

    \documentclass{article}
\usepackage[utf8]{inputenc}
\usepackage{tikz}
\usetikzlibrary{fit, backgrounds, matrix, arrows.meta}
\tikzset{
    startstop/.style={
        rectangle, rounded corners, minimum width=2cm,  
        minimum height=1.5cm,text centered, draw=black, fill=RYB2
    },
    process/.style={
        rectangle, minimum width=2.5cm, minimum height=1cm, text centered, draw=black, fill=RYB1
    },
    arrow/.style={
        blue,-{Stealth[length=6pt]}
    },  
    dasharrow/.style={
        blue, dashed,-{Stealth[length=6pt]}
    }
}

\definecolor{RYB1}{RGB}{218,232,252}
\definecolor{RYB2}{RGB}{245,245,245}

\begin{document}
\begin{figure}\centering
\begin{tikzpicture}[font=\tiny]
    % blocks
    \matrix[matrix of nodes,
        row sep=4ex,
        column sep=5.4em,
        nodes={anchor=center},
        column 2/.style={nodes={process}},
        ] (m) {
        & Text &&[-3em]\\
        |[inner sep=0pt]|\includegraphics[width=2cm]{example-image-a} & Text &&\\[-2ex]
        & Text & |[startstop]| Text & |[inner sep=0pt]|\includegraphics[height=.5cm]{example-image-b} \\[7ex]
        & Text &&\\
        & Text &&\\
    };
    % block background
    \begin{scope}[on background layer]
        \node [draw, fit=(m-1-2)(m-3-2), fill=cyan!5, inner sep=10pt] {};
        \node [draw, fit=(m-4-2)(m-5-2), fill=cyan!5, inner sep=10pt] {};
    \end{scope}    
    % vertical arrows
    \foreach[evaluate=\myblock as \mysucc using int(\myblock+1)] 
        \myblock in {1,2,...,4}
        {\draw[arrow] (m-\myblock-2) -- (m-\mysucc-2);}
    % horizontal arrows
    \coordinate (a) at ([yshift=2ex]m-2-2.west);
    \draw[dasharrow] (a) -- (m-2-1.east|-a) node[midway, above]{Text};
    \coordinate (b) at ([yshift=-2ex]m-2-2.west);
    \draw[dasharrow] (m-2-1.east|-b) -- (b) node[midway, above]{Text};
    \coordinate (c) at ([yshift=2ex]m-3-2.east);
    \draw[dasharrow] (c) -- (m-3-3.west|-c) node[midway, above]{Text};
    \coordinate (d) at ([yshift=-2ex]m-3-2.east);
    \draw[dasharrow] (m-3-3.west|-d) -- (d) node[midway, above]{Text};
    \draw[dasharrow] ([yshift=4ex]m-3-3.east) -| (m-3-4);   
    \draw[dasharrow] (m-3-4) |- ([yshift=-4ex]m-3-3.east);
\end{tikzpicture}
\end{figure}    
\end{document}

When using \fbox{\includegraphics{}} approach the result is as what shown in the figure:

How can I create a frame for such a figure?

Thank you

It seems that nobody mentioned show background rectangle option which I think it's the easier solution.

Background library is usually mentioned to draw on background layer, but it also provides show background rectangle which can be used to draw a frame around the tikzpicture. You can define a separation between borders and frame, and also the used style.

Following code shows the default solution:

\documentclass{article}
\usepackage[utf8]{inputenc}
\usepackage{tikz}
\usetikzlibrary{fit, backgrounds, matrix, arrows.meta}
\tikzset{
    startstop/.style={
        rectangle, rounded corners, minimum width=2cm,  
        minimum height=1.5cm,text centered, draw=black, fill=RYB2
    },
    process/.style={
        rectangle, minimum width=2.5cm, minimum height=1cm, text centered, draw=black, fill=RYB1
    },
    arrow/.style={
        blue,-{Stealth[length=6pt]}
    },  
    dasharrow/.style={
        blue, dashed,-{Stealth[length=6pt]}
    }
}

\definecolor{RYB1}{RGB}{218,232,252}
\definecolor{RYB2}{RGB}{245,245,245}

\begin{document}
\begin{figure}\centering
\begin{tikzpicture}[font=\tiny,show background rectangle]
    % blocks
    \matrix[matrix of nodes,
        row sep=4ex,
        column sep=5.4em,
        nodes={anchor=center},
        column 2/.style={nodes={process}},
        ] (m) {
        & Text &&[-3em]\\
        |[inner sep=0pt]|\includegraphics[width=2cm]{example-image-a} & Text &&\\[-2ex]
        & Text & |[startstop]| Text & |[inner sep=0pt]|\includegraphics[height=.5cm]{example-image-b} \\[7ex]
        & Text &&\\
        & Text &&\\
    };
    % block background
    \begin{scope}[on background layer]
        \node [draw, fit=(m-1-2)(m-3-2), fill=cyan!5, inner sep=10pt] {};
        \node [draw, fit=(m-4-2)(m-5-2), fill=cyan!5, inner sep=10pt] {};
    \end{scope}    
    % vertical arrows
    \foreach[evaluate=\myblock as \mysucc using int(\myblock+1)] 
        \myblock in {1,2,...,4}
        {\draw[arrow] (m-\myblock-2) -- (m-\mysucc-2);}
    % horizontal arrows
    \coordinate (a) at ([yshift=2ex]m-2-2.west);
    \draw[dasharrow] (a) -- (m-2-1.east|-a) node[midway, above]{Text};
    \coordinate (b) at ([yshift=-2ex]m-2-2.west);
    \draw[dasharrow] (m-2-1.east|-b) -- (b) node[midway, above]{Text};
    \coordinate (c) at ([yshift=2ex]m-3-2.east);
    \draw[dasharrow] (c) -- (m-3-3.west|-c) node[midway, above]{Text};
    \coordinate (d) at ([yshift=-2ex]m-3-2.east);
    \draw[dasharrow] (m-3-3.west|-d) -- (d) node[midway, above]{Text};
    \draw[dasharrow] ([yshift=4ex]m-3-3.east) -| (m-3-4);   
    \draw[dasharrow] (m-3-4) |- ([yshift=-4ex]m-3-3.east);
\end{tikzpicture}

[Tex/LaTex] How to define the default vertical distance between nodes

I don't really get the question so I hope this is what you wanted. If you include a full document (such that we copy paste and see the problem on our systems) things are much more easier.

Here, you can change the default setting within a scope but your block style had a node distance which was resetting every time it is issued. I've made it 2mm such that we can see the difference easier.

\documentclass[tikz]{standalone}
\usetikzlibrary{arrows,shapes.geometric,positioning}

\begin{document}
\begin{tikzpicture}[decision/.style={diamond, draw, text width=4.5em, text badly centered, node distance=3.5cm, inner sep=0pt},
                    block/.style   ={rectangle, draw, text width=6em, text centered, rounded corners, minimum height=4em, minimum height=2em},
                    cloud/.style   ={draw, ellipse, minimum height=2em},
                    line/.style    ={draw,-latex'},
                    node distance = 1cm, 
                    auto]
    \node [block] (1st) {1st};
    \node [block, right= of 1st]  (2nd1) {2nd1};
\begin{scope}[node distance=2mm and 10mm]%Here we change it for everything inside this scope
    \node [block, above= of 2nd1] (2nd2) {2nd2};
    \node [block, below= of 2nd1] (2nd3) {2nd3};
    \node [block, right= of 2nd1] (3rd1) {3rd1};
    \node [block, above= of 3rd1] (3rd2) {3rd2};
    \node [block, above= of 3rd2] (3rd3) {3rd3};
\end{scope}
    \node [block, below= of 3rd1] (3rd4) {3rd4};
    \node [block, below= of 3rd4] (3rd5) {3rd5};

    \path [line] (1st) -- (2nd1);
    \path [line] (2nd1) -- (2nd2);
    \path [line] (2nd1) -- (2nd3);
    \path [line] (2nd2) -- (3rd3);
    \path [line] (2nd1) -- (3rd1);
    \path [line] (1st) -- (2nd1);
\end{tikzpicture}
\end{document}

TikZ-PGF – Placing Node (Entity) Label on the Inside in TikZ/ERD

I guess this is one way of doing it:

\documentclass[tikz,border=5]{standalone}

\usetikzlibrary{matrix}
\begin{document}
\tikzset{
    entity/.code={
        \tikzset{
            rounded corners,             
            name=#1,
            inner sep=2pt,
            every entity/.try,
        }%
        \def\entityname{#1}%
    },
    entity anchor/.style={matrix anchor=#1},
    every entity/.style={
            draw,
    },
    every property/.style={
        inner xsep=0.20cm, inner ysep=0.075cm, anchor=west, text width=1.75in
    }
}
\def\property#1{\node[name=\entityname-#1, every property/.try]{\propertysplit#1;};}
\def\properties{\begingroup\catcode`\_=11\relax\processproperties}
\def\processproperties#1{\endgroup%
    \gdef\propertycode{}%
    \foreach \p in {#1}{%
        \expandafter\expandafter\expandafter\gdef\expandafter\expandafter\expandafter\propertycode%
            \expandafter\expandafter\expandafter{\expandafter\propertycode\expandafter\property\expandafter{\p}\\}%
    }%
    \propertycode%
}
\def\propertysplit#1:#2;{#1:\hfill#2}

\def\entitynamenode{%
\node[every entity name/.try] (\entityname-name) {\entityname};
\draw (\entityname-name.south west) -- (\entityname-name.south east);
\\[1ex]
}
\tikzset{
  every entity name/.style={every property/.try, align=center}
}

\begin{tikzpicture}[every node/.style={font=\ttfamily}, node distance=0.5in]
\matrix [entity=Employee] {
    \entitynamenode
    \properties{
        Username :  varchar(255),
        Password :  varchar(255),        
        Name :  varchar(255),
        LastName :  varchar(255)
    }
};
\end{tikzpicture}   

\end{document}
