Introducing ReQL
A database is only as good as its query language.

Thankfully, with ReQL, you get the best of both worlds as the query language is intuitive but very powerful at the same time.
An explicit query language
Instead of writing complex, SQL-like queries, ReQL lets you write practical, simple queries. One of its best features is that ReQL can be considered an explicit query language.
