You can try out MongoDB. Although it's a fully featured production ready NoSQL database, it's very easy to use. As it's a schema less DB you don't have to define schemas as you do in MySQL.
For example, you don't have to create a DB. The equivalent to create("database":"myDatabase"); in your snippet will be "use myDatabase". Similarly if you need to add a user you just do the following:
db.users.add({name : "Some Name Here"})
To remove you just need to do :
db.users.remove({name : "Some Name Here"})
It's simple. Try it out.
