data type mapping: mapping java type to hbase's bytes back and forth.
hbase operation wrapping: warpping hbase's put get scan operation to simple java interface.
hbase query language: using hbase filter, simplehbase can use sql-like style to operate on hbase.
dynamic query: like myibatis, simplehbase can use xml config file to define dynamic query to operate on hbase.
insert update support: provide insert, update on top of checkAndPut.
multiple version support: provide interface to operation on hbase's multiple version.
