在ADO.NET中处理不规则数据

Processing Irregular Data in ADO.NET

相对于关系数据库中的数据,还有一类不适合于行和列的不规则数据,如图片、声音、视频或其它特殊格式、需要经过特殊处理才能显示的数据。不规则数据长度可能会非常庞大,同时可能拥有特殊的格式。本文以图片和大型文本文件为例讨论在ADO.NET中处理不规则数据的方法。

Compared with the data in the relational database,the irregular data,such as image,audio,video,and other special format,which cannot fit with the column or row,can only be displayed after special manipulation.Moreover,the irregular data may be extremely enormous,and have special format as well.With the illustrations of processing images and mass text files,this article discusses the methods to process irregular data in ADO.NET.
