Create Cells Using Table Order & ADC<br />
For DBMS with good indexing, define Cells by concatenating (4)<br />
Adjoined Dimension Columns and sorting table by this order<br />
Each cell represents unique combination of ADC values (2,7,4,3)<br />
<br />
<br />
<br />
<br />
A Where clause with ANDed range predicates on four ADCs, each range<br />
over 3 ADC values, will select 81 cells on the table<br />
Cells Selected will not sit close to each other, except for cells differing<br />
only in the final ADC values, e.g.: (2,7,4,3) and (2,7,4,4)<br />
Obviously this approach doesn’t allow later inserts into given cells<br />
The Vertica DBMS uses this approach, but since new inserts go into<br />
WOS in memory, later merged out to disk ROS, new ad hoc inserts ARE<br />
possible<br />
