在 Tikz 上缩放图片

我正在尝试缩放我的 TikZ 图片，以便它能适合文档的第一页。我已经尝试在[scale=.8]写好的地方添加\begin{tikzpicture}，但显然不起作用。有人知道可以解决这个问题的命令吗？

谢谢

\section*{Modeling the database}
    
Use the provided SQL script ($movie_rentals.sql$) to create the movie rentals database, and then:\\[2ex]

1. Inspect the database and describe its tables using the following notation:
    \begin{align*}
&\begin{alignedat}{1}
table1(column1, column2, column3, ...)
\end{alignedat}
\\
&\begin{alignedat}{1}
column2 : FK(table2)
\end{alignedat}

\noindent

\indent \indent customer\_id: FK(customer)\\
\indent \indent movie\_id: FK(movie)\\
\end{mdframed}

2. Draw an E-R diagram for the database, by reverse engineering from the existing tables.
