通用类型

The data mining languages can be divided into three types: Inquire language, modeling language and all-purpose language. The first stage of data mining language is inquire languages, PMML is a modeling language, OLE DB for DM is a all-purpose language.

数据挖掘语言可以分为三种类型：查询语言、建模语言和通用语言，第一阶段的数据挖掘语言一般属于查询语言，PMML属于建模语言，OLE DB for DM属于通用语言。

These set of types are called CTS or Common Type System.

这些类型的一套被称为华贸或通用类型系统。

When a description of an arithmetic operator below uses the phrase "the numeric arguments are converted to a common type," this means that the operator implementation for built-in types works that way

在下面的数值运算符描述中的"数值型参数被转换为通用类型"，是指这些操作符对内置类型按如下方式工作

In Section 2.2 (p. 40) we first used string literals and learned that the type of a string literal is array of constant characters. We can now be more explicit and note that the type of a string literal is an array of const char. A string literal is an instance of a more general construct that C++ inherits from C: C-style character strings .

在 第 2.2 节中我们第一次使用了字符串字面值，并了解字符串字面值的类型是字符常量的数组，现在可以更明确地认识到：字符串字面值的类型就是 const char 类型的数组。C++从 C 语言继承下来的一种通用结构是 C 风格字符串，而字符串字面值就是该类型的实例。
