嵌套矩形

我试图得到这个数字：

在此处输入图片描述

该图由以下代码生成：

这是我在这个网站上找到的一堆代码的组合。它生成了我想要的内容，但它抱怨命令\tikzstyle，表明它不知道它是什么并且会忽略它（但当我强制它完成编译时，它会生成我想要的内容）。代码看起来相当粗糙和不雅。为了更好地学习 tikz，我想问问这个论坛上的专家是否有更简洁的方法来实现我的愿望。

我设法找到了一种更优雅的解决方案，即使用分割矩形和对齐。这至少可以消除一些单个框放置时的麻烦。也许这很有用。

  \documentclass[10pt]{article}
  \usepackage{tikz}
  \usetikzlibrary{fit,shapes,backgrounds,arrows}

  \begin{document} 

  \begin{tikzpicture}
  \tikzstyle{bigbox} = [minimum width=3.5cm, minimum height=4.2cm,draw, thick, rounded corners, rectangle]
  \tikzstyle{bigbox2} = [minimum width=2cm, draw, thick, rounded corners, rectangle]
  \tikzstyle{box} = [minimum width=2.7cm, rounded corners,rectangle]
  \tikzstyle{vbox} = [minimum width=2.7cm,rectangle,inner sep = -0.8pt]
  \tikzset{txtstyle/.style={text=black}}

 \node[align=center,draw,shape=rectangle split,
      rectangle split horizontal,
      rectangle split parts=3, text width=2cm,text centered] (A)
       {Command \\ Line \\ Interface\nodepart{two}Web \\ Interface\nodepart{three}JDBC/ \\ ODBC \\ Server};

 \node [align=center,draw,shape=rectangle split,
   rectangle split parts=3, text width=6.5cm,text centered,anchor=north] (B) at (A.south) 
    {Query Compiler\nodepart{two}Query Optimizer\nodepart{three}Query Executor};

 \node[vbox][fit=(A) (B)] (virtual) {};
 \node[align=center,shape=rectangle,draw,text width=1.5cm,text height=0.68cm,anchor=west] (C) at (virtual.east) { ~\\ ~\\ Meta \\ Data \\~ \\~ \\};

  \begin{pgfonlayer}{background}
    \node[bigbox] [fit = (virtual) (C)] (box) {};
  \end{pgfonlayer}

  \node[box,above of=A,xshift=-1.5cm] (us) {Upper System Level};

  \begin{scope}[every node/.style={minimum width=2cm,minimum height=0.5cm,rounded corners,inner sep=0pt}]
    \node [txtstyle,below of=box,yshift=-2.5cm,draw] (h1) {Master};
    \node [txtstyle,below left of=h1,yshift=-0.5cm,xshift=-2.3cm,draw] (h2) {Slave};
    \node [txtstyle,below  of=h1,yshift=-0.3cm] (h3) {...};
    \node [txtstyle,below right of=h1,yshift=-0.5cm,xshift=2.3cm,draw] (h4) {Slave};
    \node [txtstyle,above of=h2,yshift=0.3cm] (hd) {Hadooop};
  \end{scope}

  \begin{pgfonlayer}{background}
    \node[bigbox2] [fit = (hd) (h4)] (box2) {};

   \draw[<->,>=latex', shorten >=2pt, shorten <=2pt,thick] (h1.200) to (h2.north);
   \draw[<->,>=latex', shorten >=2pt, shorten <=2pt,thick] (h1.340) to (h4.north);
   \draw[->,>=latex', shorten >=2pt, thick] (box.south) to (box2.north);
     \draw[
          -triangle 90,
          line width=1.5mm,
       postaction={draw, line width=0.4cm, shorten >=0.2cm, -}
   ] (box.south) -- (box2.north);
  \end{pgfonlayer}

  \end{tikzpicture}
  \end{document}

错误消息是关于txtstyle未定义，而不是关于\tikzstyle。这需要在某处定义，因此您可以这样说：

\tikzset{txtstyle/.style={text=black}}

txtstyle或者在使用时想要应用的每种风格。

您的代码使用\tikzstyle，应\tikzset按照应该使用 \tikzset 还是 \tikzstyle 来定义 TikZ 样式？。
