Brian Proffitt of ReadWriteWeb recently wrote that while NoSQL databases may not be necessary for all companies, they are an ideal option for a large number of businesses. He writes, “The proliferation of non-relational databases in the tech sector these days could lead you to think that these data management tools (also known as NoSQL databases) are eventually going to make traditional relational databases extinct. Not so. Each of these database types is best suited for very different types of workloads, and that’s going to prevent either one from tromping the other into the dust. Which means that IT and other managers are going to have to figure out which approach is best suited for the task at hand.”

He continues, “Right off the bat, NoSQL databases are unique because they are usually independent from Structured Query Language (SQL) found in relational databases. Relational databases all use SQL as the domain-specific language for ad hoc queries, while non-relational databases have no such standard query language, so they can use whatever they want. That can, if need be, include SQL. NoSQL databases are designed to excel in speed and volume. To pull this off, NoSQL software will use techniques that can scare the crap out of relational database users — such as not promising that all data is consistent within a system all of the time. That’s a key result of using relational databases, because when you are conducting a financial transaction, such as buying something on Amazon, databases have to be very sure that one account is debited the same amount that another account is debited at the same time.”
