Abstract:
1. A computer implemented method for determining relationships among objects represented in a database, the method comprising the steps of: receiving a query including at least a first geometry and a desired relationship between the first geometry and a second geometry; providing the query to a primary filter operable to: if the second geometry fulfills the primary filter condition, providing the first geometry and the second geometry to an intermediate filter operable to: if the second geometry is confirmed as fulfilling the intermediate filter condition, including the second geometry in a final result set of objects that satisfy the desired relationship; if the second geometry is confirmed as deviating from the intermediate filter condition, excluding the second geometry from the final result set that satisfy the desired relationship; otherwise, providing the first geometry and the second geometry to a secondary filter operable to: if the second geometry fulfills the secondary filter condition, including the second geometry in the final result set of objects that satisfy the desired relationship.
