Hate it or love it, the term "NoSQL" is probably here to stay for a while. As Wikipedia says:
NoSQL is an umbrella term for a loosely defined class of non-relational data stores that break with a long history of relational databases and ACID guarantees.
InfoGrid can also use a number of other NoSQL technologies, notably to store information using the Store abstraction. However, InfoGrid does not require the use of non-relational storage; it is just as happy storing information in a relational database using other implementations of the Store abstraction also included in InfoGrid.
