    +"NoSQL" is a general term meaning that the database isn't an RDBMS which supports SQL as its primary access language, but there are many types of NoSQL databases: BerkeleyDB is an example of a local NoSQL database, whereas HBase is very much a distributed database.
+Technically speaking, HBase is really more a "Data Store" than "Data Base" because it lacks many of the features you find in an RDBMS, such as typed columns, secondary indexes, triggers, and advanced query languages, etc.
+* Automatic sharding: HBase tables are distributed on the cluster via regions, and regions are automatically split and re-distributed as your data grows.
+* MapReduce: HBase supports massively parallelized processing via MapReduce for using HBase as both source and sink.
+* Block Cache and Bloom Filters: HBase supports a Block Cache and Bloom Filters for high volume query optimization.
+* Operational Management: HBase provides build-in web-pages for operational insight as well as JMX metrics.
+If you only have a few thousand/million rows, then using a traditional RDBMS might be a better choice due to the fact that all of your data might wind up on a single node (or two) and the rest of the cluster may be sitting idle.
+Even HDFS doesn't do well with anything less than 5 DataNodes (due to things such as HDFS block replication which has a default of 3), plus a NameNode.
+HBase can run quite well stand-alone on a laptop - but this should be considered a development configuration only.
+See the <<datamodel>> and the rest of this chapter for more information on how HBase achieves its goals.

  {color:green}+1 site{color}.  The mvn site goal succeeds with this patch.
