non-relational databases

A type of index called a local non prefixed index is very useful for historical databases.

有一种索引被称为本地非前缀分区索引(localnonprefixedindex)非常适合用于存取历史数据.

Tables from different, non-local, databases are linked into DB2 UDB.

不同的、非本地的数据库中的表都链接到DB2UDB中。

In general, for the most countries, original databases can be protected through copyright law, but non-original databases ( for particular large electronic databases) can not.

一般情况下，独创性的数据库可以受到各国版权法的保护，而非独创性的数据库（尤其是大型的电子数据库）并不能满足独创性要求，从而游离在版权法的保护之外。
