| BaseTable The base type of tables. | 
| Column A Column represents the way to store a fully qualified column in a specific
 table. | 
| ColumnFamily Type safe column family. | 
| ColumnPrefix Used to represent a partially qualified column, where the actual column name
 will be composed of a prefix and the remainder of the column qualifier. | 
| RowKeyPrefix In queries where a single result is needed, an exact rowkey can be used
 through the corresponding rowkey#getRowKey() method. | 
| ValueConverter Converter used to encode/decode value associated with a column prefix or a
 column. |
