= NoSQL = Hate it or love it, the term "NoSQL" is probably here to stay for a while. As [http://en.wikipedia.org/wiki/NoSQL 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 implements one particular type of [wiki:NoSQL] technology, called a GraphDatabase. (See also Wikipedia entry on [http://en.wikipedia.org/wiki/Graph_Database Graph Databases]) !InfoGrid can also use a number of other NoSQL technologies, notably to store information using the [wiki: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 [wiki:Store] abstraction also included in !InfoGrid.
