代码（code）是程序员用开发工具所支持的语言写出来的源文件，是一组由字符、符号或信号码元以离散形式表示信息的明确的规则体系。
对于字符和Unicode数据的位模式的定义，此模式代表特定字母、数字或符号（例如 0x20代表一个空格，而 0x74代表字符“t”）。一些数据类型每个字符使用一个字节；每个字节可以具有 256个不同的位模式中的一个模式。
在计算机中，字符由不同的位模式（ON或 OFF）表示。每个字节有 8位，这 8位可以有 256种不同的 ON和 OFF组合模式。对于使用 1个字节存储每个字符的程序，通过给每个位模式指派字符可表示*多 256个不同的字符。2个字节有 16位，这 16位可以有 65,536种**的 ON和 OFF组合模式。使用 2个字节表示每个字符的程序可表示*多 65,536个字符。
单字节代码页是字符定义，这些字符映射到每个字节可能有的 256种位模式中的每一种。代码页定义大小写字符、数字、符号以及!、@、#、*等特殊字符的位模式。每种欧洲语言（如德语和西班牙语）都有各自的单字节代码页。
虽然用于表示 A到 Z拉丁字母表字符的位模式在所有的代码页中都相同，但用于表示重音字符（如"é"和"á"）的位模式在不同的代码页中却不同。如果在运行不同代码页的计算机间**数据，必须将所有字符数据由发送计算机的代码页转换为接收计算机的代码页。如果源数据中的扩展字符在接收计算机的代码页中未定义，那么数据将丢失。
如果某个数据库为来自许多不同**的客户端提供服务，则很难为该数据库选择这样一种代码页，使其包括所有客户端计算机所需的全部扩展字符。而且，在代码页间不停地转换需要花费大量的处理时间。
