The NoSQL movement faults the SQL query language as the source of many of the scalability issues that we face today with traditional database approach.

I think that the main reason so many people have come to see SQL as the source of all evil is the fact that, traditionally, the query language was burned into the database implementation. So by saying NoSQL you basically say "No" to the traditional non-scalable RDBMS implementations.

This view has brought on a flood of alternative query languages, each aiming to solve a different aspect that is missing in the traditional SQL query approach, such as a document model, or that provides a simpler approach, such as Key/Value query.

Most of the people I speak with seem fairly confused on this subject, and tend to use query semantics and architecture interchangeably. In Part I of this post i tried to provide quick overview of what each query term stands for in the context of the NoSQL world . Part II illustrates those ideas using code examples from GigaSpaces and Datanucleus

/Hbase.
