结构化查询语言和非结构化查询语言之间的区别 [英] difference between structured query language and unstructured query language

问题描述

你可以帮我理解结构化查询语言和非结构化查询语言之间的区别......

解决方案

< blockquote class =FQ>

维基百科 告诉我们：

UnQL（非结构化查询语言）是 SQL 的功能超集，由 SQLite 和 CouchDB

另请参阅：

http://en.wikipedia.org/wiki/SQL#Criticism [ ^ ]，

http：//en.wikipedia .org / wiki / Relational_model [ ^ ]，

http：// en .wikipedia.org / wiki / Tuple_relational_calculus [ ^ ] 。



你还应该明白，关于差异的问题在大多数情况下在逻辑上是不正确的。如你所见，你的问题结果就像是汽车与丰田之间的区别。 :-)

Hi,
can u help me what is the difference between structured query language and unstructured query language...

解决方案

Wikipedia tells us:

UnQL (Unstructured Query Language) is a functional superset of SQL, developed by the authors of SQLite and CouchDB

See also:
http://en.wikipedia.org/wiki/SQL#Criticism[^],
http://en.wikipedia.org/wiki/Relational_model[^],
http://en.wikipedia.org/wiki/Tuple_relational_calculus[^].

You should also understand that questions about "differences" are in most cases logically incorrect. As you can see, your question turns out to be like "what's the difference between a car and Toyota". :-)

Summed up in these quite well
