Redis transactions allow to group multiple commands and to execute them sequentially. The whole transactional state is isolated from other users and becomes visible once a transaction is committed.

Introductory NoSQL stuff

software-development-2-logo

While some of you might be NoSQL gurus, there is often a lack of solid knowledge about NoSQL in general and some common myths as well.
