人们在使用SQL时往往会陷入一个误区，即太关注于所得的结果是否正确，而忽略了不同的实现方法之间可能存在的 性能差异，这种性能差异在大型的或是复杂的数据库环境中（如联机事务处理OLTP或决策支持系统DSS）中表现得尤为明 显。笔者在工作实践中发现，不良的SQL往往来自于不恰当的索引设计、不充份的连接条件和不可优化的where子句。在对 它们进行适当的优化后，其运行速度有了明显地提高！下面我将从这三个方面分别进行总结：-people in the use of SQL often fall into the trap, that is too focused on the findings is correct, and ignore a different method may exist between the performance differences, these differences in large or complex database environment (such as online transaction processing or decision support OLTP system DSS) has become even more obvious. In practice I found that the poor tend to SQL from inappropriate design of the index, not fully connected and non-optimal conditions where the phrase. On their proper optimization, and their operating speed has been improved! Now I will be three aspects of this summary :

在设计一个应用程序时候往往会遇到大量的数据，而处理这些数据又会经常使用到表格。在使用表格对数据进行操作时能够既快速又准确-application in the design of a procedure often encountered when large amounts of data, and the processing of these data will be used to form. The use of forms for data processing can be both fast and accurate

本代码用7.0开发。完全由我独自编写。还没有最终完成，但已经能演示一些重要的功能了。进入程序后，执行“打开”。然后在“帮助”菜单下，可以动态画一些控件。-7.0 of the code used to develop. Entirely my own preparation. Also not finalized, but will have demonstrated some important features. Entry procedures, the implementation of the "open." Then in the "Help" menu, we can draw some of Dynamic Controls.

国际流行的界面风格，很多商业软件均采用，不可思议的是初自一位国外14岁的少年之手。这个是经过改进的版本，加入了菜单功能。-international pop style of interface, many commercial software applications used, it is inconceivable since the beginning of a foreign 14-year-old boy"s hands. This is an improved version by adding a menu function.
