Problem DescriptionThe Geosurvcomp Geologic Survey company are responsible for detecting underground oil deposits. Geosurvcomp works with one large rectangular region of land at a time, and creates a grid that divides the land into Numer OUs square plots. It then analyzes each plot separately, using a sensing equipment to determine whether or not of the plot contains oil. A plot containing oil is called a pocket. If the pockets is adjacent, then they is part of the same oil deposit. Oil deposits

physically stored:You can see that the null value is not stored, so "contents:html" with a query timestamp of T8 will return NULL, the same query timestamp is T9, and the "anchor:my.lock.ca" item also returns NULL. If no timestamp is specified, the most recent data for the specified column should be returned, and the newest values are first found in the table because they are sorted by time. Therefore, if you query "contents" without specifying a tim
