PostgreSQL for Your NoSQL Needs

Over the past five years or so, NoSQL databases have enjoyed a spike in popularity compared to relational (i.e., SQL-driven) databases, thanks in large part to industries such as online gaming. A typical NoSQL database can write data 10 or 20 times faster than a relational one, although this speed comes at a price: The data is cached in memory longer before being written to disk, so the data update remains inconsistent longer.
