为了高效地管理XML数据，像传统的SQL数据类型一样，DB 2在内部使用XML数据模型作为逻辑数据模型，同时也作为物理存储的基本单元。

To efficiently manage XML data, like traditional SQL data types, DB2 USES the XML data model internally, as the logical data model and as the fundamental unit of physical storage.

这些基本运算都可通过空间编码与解码的光学逻辑实现，从而提供了一种有效的光学算术-逻辑单元（ALU）设计方案。

The arithmetic is realized by logic operations and implemented by the spatial encoding technique, which offers an efficient design of optical arithmetic logic unit(ALU).
