什么是CouchDB

Question

So what is couchDB exactly? taking out all the fancy technical terms.

Is it an alternative to MySQL basically?

Thanks

Answer 1

Basically, in MySQL you store rows and tables. In CouchDB you store documents (which can be also describes as rows and tables, but lets get to the highest abstraction level). It isn't alternative to MySQL, as it it designed for different purposes.
