Title: METHOD FOR HANDLING A DATABASE
Abstract:
The invention relates to a method for handling a database containing objects (A, B) that have an extension in a coordinate system representing a multidimensional reality, which coordinate system is divisible into a plurality of defined, multidimensional intervals (61-69). The method is characterised by the steps of, each time an object is entered into the database, determining which multidimensional intervals the object has an extension in, for each of these intervals determining the number of objects having an extension therein, comparing said number of objects with a predetermined threshold value and, if the threshold value is exceeded, dividing the interval into at least two smaller intervals, in order to limit the number of objects related to an extension in an optional, defined interval. Each interval (61-69) is linked to a set of objects (A, B) having an extension in the interval and each object (A, B) is linked to a set of intervals (61-69) within which the object has an extension. In accordance with the invention a dynamic space map is produced.
