===Views===__NOEDITSECTION__
A series of database views are pre-defined on the staging area, three for each object: <OBJECT>_POINT_VIEW, <OBJECT>_POLYGON_VIEW and <OBJECT>_POLYLINE_VIEW - where <OBJECT> is HAZARD, GAZETTEER, MRE, etc. - each object that potentially has associated geodata. Each view is defined as an '''INNER JOIN''' between the <OBJECT> table, e.g. HAZARD, and each of the three geodata tables. The inner join means that data from e.g. the HAZARD table that has '''no''' polygon associated will not be found in the HAZARD_POLYGON_VIEW. Depending on the use case, either the tables or the views can be accessed.
