An applet is a small application that resides on a server. When a client connects to that server over the Web, the applet is downloaded and starts running in the client computer. Java applets are specially designed so that they run in a sandbox. A sandbox is a well-defined area in the client computer’s memory where the downloaded applet can run. The applet is not allowed to affect anything outside the sandbox. This architecture is designed to protect the client machine from potentially hostile applets that may try to extract sensitive information or cause malicious damage.
You face a certain amount of danger when you download anything from a server that you do not know to be trustworthy. If you download a Java applet, that danger is greatly reduced, but not completely eliminated. Be wary about letting executable code enter your machine from a questionable server.
Like ODBC, JDBC passes SQL statements from the front-end application (applet) running on the client to the data so

Applet程序就是服务器上的一个小应用程序。当一个客户端通过网络连接到该服务器，插件就会被下载并在用户的计算机上运行。Java程序是特殊设计的程序，它们在沙盒中运行。沙盒是一个客户端内存中的自定义域，被下载的程序能在其中运行。Applet程序是不允许影响沙盒以外的任何程序的。这种设计结构是为了保护客户端计算机，防止从潜在的敌对应用程序尝试提取敏感信息或造成恶意的破坏.当你从服务器下载任何你不了解或者不信任的程序，你都会面临一定的危险。如果你下载了Java程序,其危险性大大降低,但并没有完全消除.应该注意小心不要让那些来自于可疑服务器的可执行代码进入你的计算机。像ODBC一样，JDBC把SQL语言陈述从运行在客户端上的前端应用程序（Applet程序）发送到后端的数据源。使用JDBC的作用在于Applet的编写者可以在不需要知道或者不用在乎位于后端的是什么数据库的情况下，向标准的JDBC接口进行写入。无论精确的双向通讯是否必须要转换，JDBC都可以执行。
