    +	  <para>HBase is a type of "NoSQL" database.  "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,
+	  <para>However, HBase has many features which supports both linear and modular scaling.
 HBase clusters expand
+	  by adding RegionServers that are hosted on commodity class servers. If a cluster expands
from 10 to 20
+	  RegionServers, for example, it doubles both in terms of storage and as well as processing
capacity.
+	  RDBMS can scale well, but only up to a point - specifically, the size of a single database
server - and for the best
+              <listitem><para>Strongly consistent reads/writes:  HBase is not
an "eventually consistent" DataStore.  This
+              makes it very suitable for tasks such as high-speed counter aggregation.</para>
